In this crossover session, we invite studies on the latest advancements in analytical and experimental techniques from all relevant fields dealing with geochemical processes or applying chemical/isotope data to assess the dynamics in geological systems. Relevant are all-new achievements of techniques more or less established in Earth sciences. Moreover, new techniques or experiments brand-new to Earth sciences are of particular interest. Techniques are welcome from mass spectrometry, photon/electron-based spectroscopy, including microscopy and measurements under various conditions (ambient to non-ambient) and spatial resolutions. The overarching breadth of this session will foster the exchange between the communities.
Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.
The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.
This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.
Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
This session is open to all contributions in biogeochemistry and ecology where stable isotope techniques are used as analytical tools, with foci both on stable isotopes of light elements (CHONS …) and new systems (clumped and metal isotopes). We welcome studies from both terrestrial and aquatic (including marine) environments as well as methodological, experimental and theoretical studies that introduce new approaches or techniques (including natural abundance work, labelling studies, multi-isotope approaches).
Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
The nature of Earth’s lithospheric mantle is largely constrained from the petrological and geochemical studies of xenoliths. They are complemented by studies of orogenic peridotites and ophiolites, which show the space relationships among various mantle rock types, missing in xenoliths. Mantle xenoliths from cratonic regions are distinctly different from those occurring in younger non-cratonic areas. Percolation of melts and fluids through the lithospheric mantle significantly modifies its petrological and geochemical features, which is recorded in mantle xenoliths brought to the surface by oceanic and continental volcanism. Basalts and other mantle-derived magmas provide us another opportunity to study the chemical and physical properties the mantle. These various kinds of information, when assembled together and coupled with experiments and geophysical data, enable the understanding of upper mantle dynamics.
This session’s research focus lies on mineralogical, petrological and geochemical studies of mantle xenoliths, orogenic and ophiolitic peridotites and other mantle derived rocks. We strongly encourage the contributions on petrology and geochemistry of mantle xenoliths and other mantle rocks, experimental studies, the examples and models of mantle processes and its evolution in space and time.
Subduction is one of the primary mechanisms of fluid and element cycling between
the surface and mantle in the Earth. During subduction, metamorphism in the
downgoing plate and the consequent expulsion of fluids and generation of melts
drives mineralogical, geochemical, and rheological changes affecting the mechanical
behaviour of the subducting zone system. These fluids and melts play a key role in
the long-term geochemical evolution of the Earth by preferentially fractionating
elements from the slab and introducing them to the mantle wedge, volcanic arc, and
forearc. This process is particularly relevant for volatiles, such as carbon, which can have a profound influence on the habitability of the Earth's surface. This session aims to bring together the petrology, geochemistry, geodynamics, tectonics, and geochronology community by linking subduction zone inputs, outputs and mechanisms over a range of length and timescales. We especially encourage studies that constrain the conditions, durations, and geochemical evolution of metamorphic, metasomatic, and magmatic processes leading to the transfer of material from the slab into the mantle wedge, forearc, arc, and deep mantle. We encourage participation from scientists from all backgrounds and levels of experience.
Subduction drives plate tectonics, generating the major proportion of subaerial volcanism, releasing >90% seismic moment magnitude, forming continents, and recycling lithosphere. Numerical and laboratory modeling studies have successfully built our understanding of many aspects of the geodynamics of subduction zones. Detailed geochemical studies, investigating compositional variation within and between volcanic arcs, provide further insights into systematic chemical processes at the slab surface and within the mantle wedge, providing constraints on thermal structures and material transport within subduction zones. However, with different technical and methodological approaches, model set-ups, inputs, and material properties, and in some cases conflicting conclusions between chemical and physical models, a consistent picture of the controlling parameters of subduction-zone processes has so far not emerged.
This session aims to follow subducting lithosphere on its journey from the surface down into the Earth's mantle and to understand the driving processes for deformation and magmatism in the over-riding plate. We aim to address topics such as: subduction initiation and dynamics; changes in mineral breakdown processes at the slab surface; the formation and migration of fluids and melts at the slab surface; primary melt generation in the wedge; subduction-related magmatism; controls on the position and width of the volcanic arc; subduction-induced seismicity; mantle wedge processes; the fate of subducted crust, sediments and volatiles; the importance of subducting seamounts, LIPs, and ridges; links between near-surface processes and slab dynamics and with regional tectonic evolution; slab delamination and break-off; the effect of subduction on mantle flow; and imaging subduction zone processes.
With this session, we aim to form an integrated picture of the subduction process, and invite contributions from a wide range of disciplines, such as geodynamics, modeling, geochemistry, petrology, volcanology, and seismology, to discuss subduction zone dynamics at all scales from the surface to the lower mantle, or in applications to natural laboratories.
The origin and evolution of the continental lithosphere is closely linked to changes in mantle dynamics through time, from its formation through melt depletion to multistage reworking and reorganisation related to interaction with melts formed both beneath and within it. Understanding this history is critical to constraining terrestrial dynamics, element cycles and metallogeny. We welcome contributions dealing with: (1) Reconstructions of the structure and composition of the lithospheric mantle, and the influence of plumes and subduction zones on root construction; (2) Interactions of plume- and subduction-derived melts and fluids with the continental lithosphere, and the nature and development of metasomatic agents; (3) Source rocks, formation conditions (P-T-fO2) and evolution of mantle melts originating below or in the mantle lithosphere; (4) Deep source regions, melting processes and phase transformation in mantle plumes and their fluids; (5) Modes of melt migration and ascent, as constrained from numerical modelling and microstructures of natural mantle samples; (6) Role of mantle melts and fluids in the generation of hybrid and acid magmas.These topics can be illuminated using the geochemistry and fabric of mantle xenoliths and orogenic peridotites, mantle-derived melts and experimental simulations.
Dear collegues Dear all.
Thank you very much for all presentations! The quality of most was very high.
Aspecially we shou be grateful to Sonja Aulbach who was a a wonderful presenter of the session. Hope next year the situation will be better and more participants will be participated personally in Vienna. There is one opened spacial issue in Minerals https://www.mdpi.com/journal/minerals/special_issues/Deep_Seated_Melts. I'll try to find the possibility for another one not so expensive.
Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.
Cratons form the ancient, stable cores of most of the Earth’s continents. Knowledge about the present-day architecture of cratons is the key to understand the evolution of continental plates. In addition to that, cratons concentrate many economically relevant mineral deposits, which are indispensable for a modern society. For many cratonic regions however, little is still known about the present-day lithospheric structure and how it evolved since the Archean, mainly due to their remoteness and harsh local environmental conditions. Ongoing data acquisition, as well as the usage and optimization of
remote and passive techniques have shed new light on the lithospheric architecture of cratonic regions. Recent advancements across several disciplines show that cratons are more varied and fragmented than previously assumed, which has strong implications for geodynamic interactions with the convective mantle and long-term stability.
In this session, we welcome contributions across different scales that describe the cratonic lithosphere and its evolution with time, up to the dawn of plate tectonics. We aim to address topics like: characterization and evolution of cratonic crust and lithosphere; coupling between cratonic crust and mantle; mechanisms to form, maintain and destroy cratonic roots; craton-plume interaction; the role of cratons in supercontinent configurations; connection of cratons to mineral deposits.
We would like to raise discussions within a multidisciplinary session and therefore welcome contributions across a wide range of disciplines, including, but not limited to geodynamics, geology, tectonics, seismology, gravity, geochemistry, petrology, as well as joint approaches.
The present state of Earth and other rocky planets are an expression of dynamical and chemical processes occurring throughout their history. In particular, giant impacts, core formation and magma-ocean crystallisation and other processes occurring in the early solar system set the stage for the long-term evolution of terrestrial planets. These early processes can happen simultaneously or in recurring stages, and are ultimately followed by progressive crustal growth, long-term mantle mixing/differentiation, core-mantle interaction, as well as inner-core crystallization. The rock-record, through geochemistry and magnetism, is used to interrogate changes in the tectono-thermal regime of Earth’s interior through time, while seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the contemporary mantle, crust and core. These classes of observations may be linked through geodynamic models, whose accuracy is underpinned by the physical properties (e.g., viscosity and density) of its constituent phases (minerals, melts and fluids). Information on the fundamental thermodynamic and physical behaviour of phases is subject to constant advance via experimental and ab-initio techniques.
This session aims to provide a holistic view of the formation, dynamics, structure and composition of Earth and the evolution of terrestrial bodies by bringing together studies from geophysics, geodynamics, mineral physics, geochemistry, and petrology. This session welcomes contributions focused on data analysis, modeling and experimental work that address the formation and evolution of terrestrial planets and moons in the Solar System, and around other stars.
Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
Mineralogy is the cornerstone of many disciplines and is used to solve a wide range of questions in geoscience. This broad session offers the opportunity to explore the diversity of methods and approaches used to study minerals and how minerals behave and evolve in their many contexts. We welcome contributions on all aspects of mineralogy, including environmental, soil science, metamorphic, plutonic, deep Earth, planetary, applied mineralogy, and so on. All approaches are welcome: analytical, experimental and theoretical.
Mineral deposits represent principal sources of metallic and non-metallic raw materials for our society. The implementation of new climate policies and the rise of green energy production and use will trigger an unprecedented demand increase for such resources. Formation of economic commodities requires component sequestration from source region, transport and focusing to structural or chemical barriers. These enrichment processes typically involve magmatic, hydrothermal, weathering or metamorphic events, which operate in diverse geodynamic settings and over various time scales. The scope of this session is to collect insights from diverse areas of mineral exploration, field, analytical or experimental studies of mineral deposits as well as resource characterization and extraction. We invite contributions from fields of economic geology, mineralogy and geochemistry in order to advance our understanding of ore-forming systems.
Lithosphere evolution, reflected in the lithosphere structure, controls the deposition of mineral resources, many of which occur in specific geodynamic settings. We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes modify the lithosphere structure, control ore deposits, and how these processes changed during the Earth's evolution. We particularly invite contributions with focus on regional geophysical studies of the crust and upper mantle.
This session is a part of the International Lithosphere Program Task Force 1. We invite contributions from everyone interested in the topic and invite them to join the ILP TF1.
Minerals are formed in great diversity under Earth surface conditions, as skeletons, microbialites, speleothems, or authigenic cements, and they preserve a wealth of geochemical, biological, mineralogical, and isotopic information, providing valuable archives of past environmental conditions. Interpreting these archives requires fundamental understanding of mineral formation processes, but also insights from the geological record.
In this session we welcome oral and poster presentations from a wide range of research of topics, including process-oriented studies in modern systems, the ancient rock record, experiments, computer simulations, and high-resolution microscopy and spectroscopy techniques. We intend to reach a wide community of researchers sharing the common goal of improving our understanding of the fundamental processes underlying mineral formation, which is essential to read our Earth’s geological archive.
The demand for raw materials and critical raw materials, to supply the needs of both society and industry, is continuously growing, imposing environmental, societal, and technological challenges.
These activities are inevitably accompanied by the production of large volumes of residues, through both exploitation and processing.
In the past, mining activity and extractive waste management were approached, mainly considering the environmental hazards and landscape degradation, but, nowadays, the development of innovative and technological processes, that allow us to reduce, reuse and recycle such industrial residues, as well as more sustainable exploitation practices, give us the opportunities to exploit the huge volumes of past mineral waste as an important source of raw materials.
Residues, such as waste rock, tailings, slags and fly ashes, often hold impressive residual mineral values, and have the potential to be converted to secondary raw materials and mineral resources, for these reasons further challenges are the geochemical, petrographic and mineralogical characterization and the modelization of waste deposits to realistically assess the prospects for sustainable exploitation. It must become the norm to maximize resource use, reduce the volume for final disposal, and also mitigate the risk of environmental damage, associated with the increasing global demand for raw materials and minerals resources.
The main topics to be discussed in this session address, but are not limited to:
- Characterization of geomaterials, their environmental interactions, and decay
- Characterization of industrial residue resources and their environmental assessment
- Secondary raw materials exploitation and valorisation
Reactions between fluids and rocks have a fundamental impact on many of the natural and geo-engineering processes in crustal settings. Examples of such natural processes are localization of deformation, earthquake nucleation caused by high pressure fluid pulses, as well as metamorphic reactions and rheological weakening triggered by fluid flow, metasomatism and fluid-mediated mass transport. Moreover, the efficiency of many geo-engineering processes is partly dependent on fluid-rock interactions, such as hydraulic fracturing, geothermal energy recovery, CO2 storage and wastewater injection. All our observations in the rock record are the end-product of all metamorphic, metasomatic and deformation changes that occurred during the interaction with fluid. Therefore, to investigate and understand these complex and interconnected processes, it is required to merge knowledge and techniques deriving from several disciplines of the geosciences.
We invite multidisciplinary contributions that investigate fluid-rock interactions throughout the entire breadth of the topic, using fieldwork, microstructural and petrographic analyses, geochemistry, experimental rock mechanics, thermodynamic modeling and numerical modeling.
Hydrothermal systems exert crucial influence on volcanic hazards. For example, hydrothermal alteration can reduce the strength of edifice- and dome-forming rocks, increasing the likelihood of volcano spreading and flank collapse, and high pore pressures that develop within hydrothermal systems can promote phreatic/phreatomagmatic explosions and further increase volcano instability. On the other hand, hydrothermal systems also offer the opportunity to exploit minerals of economic interest, and their heat can be harnessed to produce energy. A detailed understanding of hydrothermal systems and their resulting alteration, using multidisciplinary studies, is required to better anticipate the hazards posed, to exploit the economic opportunities they provide, and to execute engineering design. We invite diverse contributions dedicated to the characterisation, imaging, monitoring, and hazard/economic assessment of volcanic hydrothermal systems. Contributions can be based on fieldwork, laboratory work, modelling, or a combination of these approaches. Because understanding hydrothermal systems requires multidisciplinary, collaborative teamwork, we welcome contributions based on any subdiscipline (e.g., geology, geophysics, geochemistry, engineering) and using any technique or method (e.g., geological mapping, magnetic, gravity, and spectroscopic methods, laboratory experiments, gas monitoring, numerical modelling). It goes without saying that we hope to have a diverse session in terms of both speakers and audience.
Fluid flow in the Earth’s crust is driven by pressure gradients and temperature changes induced by internal heat. The expression of crustal fluid flow is associated with a range of structural and geochemical processes taking place in the basement but also in sedimentary covers forming the upper crust. Groundwater, hydrothermal brines and gases circulating in the subsurface interact with local structures across different tectonic and geological settings. Under near-lithostatic conditions fluids and rocks are expelled vertically to the near-surface featuring a variety of surficial geological phenomena ranging from hydrothermal systems to sedimentary and hybrid volcanism and cold seeps both on land and along continental margins. These vertical fluid flow expressions and piercement structures are characterized by complex sedimentary deformation and geochemical reactions where life can adapt to thrive in extremely harsh environments making them ideal windows to the deep biosphere. Several studies have shown that CO2- and CH4-dominaterd (or hybrid) vents played a key role in the evolution of our planet and the cycles of life during several geological eras. Furthermore, the elevated pore pressures often encountered in reservoirs at depth make piercements ideal natural laboratories to capture precursors of seismic events and dynamically triggered geological processes. Yet, the geochemical and geophysical processes associated with the evolution of these vertical fluid flow features and piercements remain poorly understood.
This session welcomes contributions from the community working at the interface between magmatic and sedimentary environments using geophysical, geochemical, microbial, geological, numerical and laboratory studies to promote a better understanding of modern and paleo fluid-driven systems in the upper crust. In particular we call for contributions from: 1) investigations of tectonic discontinuities pre-existing geological structures; 2) the geochemical reactions occurring at depth and at the surface including microbiological studies; 3) geophysical imaging and monitoring of fluid flow systems associated with vertical fluid expulsion at the upper crust; 4) experimental and numerical studies about fluid flow evolution; 5) studies of piercement dynamics related to climatic and environmental implications.
Fluid-mediated rock transformation, also called mineralogical replacement, are ubiquitous instances of fluid-rock interaction in the crust. With recent developments in measurement techniques, the characterization and understanding of replacement has potential to unravel fluid dynamics and migration pathways, the volume of reactive fluids involved, the deformation associated to the reaction, along with the thermodynamical properties of the reaction. The ambition of the proposed session is to draw a picture of the current state of knowledge about the driving processes of fluid-mediated transformation in the diagenetic domain and in the low metamorphic conditions, with or without associated deformation. We welcome any contribution focusing on methodological, experimental, analytical or nature-related studies of mineralogical replacements and associated phenomenon.
Dissolution, precipitation, and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).
Garnet is probably the most useful mineral to understand the evolution of basement areas on Earth particularly those characterized by high-temperature metamorphism. This mineral allows us to decipher the metamorphic evolution of different rock types by the thermobarometric information stored in the variable chemical composition of zoned garnet. In addition, garnet (1) preserves mineral assemblages formed during prograde metamorphism, (2) can be used to date specific metamorphic events, and (3) forms by partial melting of a rock leading to dense restites. According to recent progress in a better understanding of the characteristics of garnet and their application and modelling to natural rocks, we invite a broad spectrum of geoscientists, including petrologists, geochemists, and structural geologists to present their studies involving garnet to this interdisciplinary symposium. These studies should include experimental aspects as well as case-studies of rocks with emphasis on garnet.
Metamorphic minerals provide unique records of the tectonic processes that have shaped Earth through the ages. Innovative new approaches in metamorphic petrology, chemical and isotope micro-analysis, and geochronology provide exciting new avenues to let these minerals tell their story of deformation, reaction and fluid flow. The insights from such research provide key means of testing long-standing concepts in petrology and tectonics, and shifting paradigms in these fields.
This session will highlight integrated metamorphic petrology, with application to tectonics and development of collisional orogens, cratons and subduction zones. We welcome contributions, from petrology, (petro-)chronology, to trace-element and isotope geochemistry. Through these diverse insights, the session will provide an exciting overview of current research on metamorphic and metasomatic processes, as well as the avenues for future innovation.
The goal of this session is to reconcile short-time/small-scale and long-time/large-scale observations, including geodynamic processes such as subduction, collision, rifting, or mantle lithosphere interactions. Despite the remarkable advances in experimental rock mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local lithological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions, and deformation rates.
Mineral reactions have mechanical effects that may result in the development of pressure variations and thus are critical for interpreting microstructural and mineral composition observations. Such effects may fundamentally influence element transport properties and rheological behavior.
Here, we encourage presentations focused on the interplay between metamorphic processes and deformation on all scales, on the rheological behavior of crustal and mantle rocks, and time scales of metamorphic reactions in order to discuss
(1) how and when up to GPa-level differential stress and pressure variations can be built and maintained at geological timescales and modeling of such systems,
(2) deviations from lithostatic pressure during metamorphism: fact or fiction?
(3) the impact of deviations from lithostatic pressure on geodynamic reconstructions.
(4) the effect of porous fluid and partial melting on the long-term strength.
We, therefore, invite the researchers from different domains (rock mechanics, petrographic observations, geodynamic and thermo-mechanical modeling) to share their views on the way forward for improving our knowledge of the long-term rheology and chemo-thermo-mechanical behavior of the lithosphere and mantle.
The timescale of magma formation, storage and ascent beneath active volcanoes is crucial to constrain the magma chamber dynamics and provide the basis for volcanic hazard assessment. The interpretation of rock textures is the key step of the back-analysis studies targeted at the reconstruction of the magma chamber dynamics and depends on our understandings of the crystallization kinetic processes in silicate melts. Beside crystal formation, dissolution and reaction of pre-existing crystals, are processes that commonly affect the kinetics of magma crystallization and that, however, are broadly constrained from the theoretical and the experimental point of view.
Experimental studies can shed a light on subterranean processes generating eruptions, constraining pre- and syn-eruptive physical and chemical key magmatic variables such as pressure, temperature, volatile and crystal content, melt composition and viscosity. A major goal of modern experimental studies is to constrain the physical and chemical parameters of deep magmatic reservoirs, such as those located at Moho-lower crust boundary.
This session invites contributions dealing with the nucleation and growth of minerals, the “fate of pre-existing crystals”, the effects of crystallization kinetics on mineral chemistry as well as the partitioning of trace elements between crystals and melts during high-pressure differentiation and storage of magmas. We particularly encourage submissions on experimental petrology, thermodynamic and geochemical modelling, as well as on field studies.
Volcanic settings host a variety of complex and interconnected processes that can significantly control their eruptive behaviour. Magmas can reside at a certain depth in the crust for a relatively long time and erupt almost instantaneously. During the time spent at depth, magmas can evolve via fractional crystallization, mingle and mix with new magmas of deeper origin and interact with the wall rocks, whereas during ascent, decompression typically triggers degassing and crystallization. Both magma chamber and conduit processes play a pivotal role in controlling the geochemical and physical properties of magmas that strongly affect the frequency and style of eruption. As investigation of such processes cannot be performed via direct observations, we analyse the texture and composition of the erupted products to acquire information about magma evolutionary processes and conduit dynamics using a variety of techniques. In addition, we can design experimental setups and numerical simulations aimed at reproducing the natural conditions of magma storage and ascent. In this session we welcome contributions that provide insights into volcanic and igneous plumbing systems (VIPS) dynamics using petrology, volcanology, thermodynamics and modelling tools. We particularly welcome studies that integrate different approaches to unravel magmatic processes and timescales that lead to eruption.

The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.
This session is devoted to the most recent eruption of the Cumbre Vieja volcano, which started on Sept. 19, 2021, on the island of La Palma after 50 years of repose. Volcanic unrest was recorded in Oct. 2017, when a seismic swarm was located at more than 20 km depths. Nine additional swarms followed, the last one was recorded in June 2021. Geochemical anomalies followed this increased seismicity indicating a magmatic recharge at depth. On Sept. 11, 2021, a new seismic swarm was observed at shallower depths (10-12 km), indicating a possible magmatic intrusion. This was confirmed when geodetic monitoring networks on the island started showing clear signs of inflation. The seismicity increased in frequency and intensity with many felt earthquakes. Seismic activity accelerated in the morning of Sept. 19 when a strong shallow earthquake was widely felt on the western part of the island. This was the precursor of the eruption, which started at about 14:10 UTC on the same day. A series of vents opened along a fissure close to Los Llanos on the western flank of Cumbre Vieja volcano. The eruption displayed vigorous lava fountaining and powerful Strombolian explosions while lava effusion produced a compound Aa flow field. The eruption has destroyed hundreds of buildings, plantations as well as cutting vital transport routes.
This session is open to contributions aimed at geological, geophysical, geochemical and volcanological studies of the eruption and its precursors and, more in general, to studies that can help better understanding the eruptive dynamics. We also welcome contributions focused on the management of scientific communication during this crisis and the management of the volcanic emergency.
Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.
The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks.
Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome.
We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources.
The session includes, but is not restricted to, the following topics:
volcanism and regional tectonics;
formation of magma chambers, laccoliths, and other intrusions;
dyke and sill propagation, emplacement, and arrest;
earthquakes and eruptions;
caldera collapse, resurgence, and unrest;
volcano deformation monitoring;
volcano deformation and hazard mitigation;
mechanical properties of rocks in volcanic areas.
Over the past few years, major technological advances significantly increased both the spatial coverage and frequency bandwidth of multi-disciplinary observations at active volcanoes. Networks of instruments, both ground- and satellite-based, now allow for the quantitative measurement of geophysical responses, geological features and geochemical emissions, permitting an unprecedented, multi-parameter vision of the surface manifestations of mass transport beneath volcanoes. Furthermore, new models and processing techniques have led to innovative paradigms for inverting observational data to image the structures and interpret the dynamics of volcanoes. In particular, machine learning, a type of AI in which computers learn from data, is gaining importance in volcanology, not only for monitoring purposes (i.e., in real-time) but also for later hazards analysis (e.g. modelling tools).
Within this context, this session aims to bring together a multidisciplinary audience to discuss the most recent innovations in volcano imaging and monitoring, and to present observations, methods and models that increase our understanding of volcanic processes.
We welcome contributions (1) related to methodological and instrumental advances in geophysical, geological and geochemical imaging of volcanoes, (2) to explore new knowledge provided by these studies on the internal structure and physical processes of volcanic systems, and (3) to investigate the potential of machine learning techniques to process multispectral satellite data for developing a better understanding of volcanic hazards.
We invite contributors from all geophysical, geological and geochemical disciplines: seismology, electromagnetics, geoelectrics, gravimetry, magnetics, muon tomography, volatile measurements and analysis. The session will include in-situ monitoring and high- resolution remote sensing studies that resolve volcanic systems ranging from near-surface hydrothermal activity to deep magma migration.
The impact of magma-sediment interactions in the top wet sediments of active sedimentary basins is poorly quantified. Yet this accelerator of diagenetic processes, impacts important fields of geology ranging from potential ocean-climate disorder due to petroleum mobilization and emission, to catabolic power supply for deep microbial activity. With one end-member killing life and the other fueling it, can we derive the implications at the scale of the plate cycle? This session calls for contributions that help to understand the magma-sediment interaction processes in the first 500 m of active sedimentary basins and how it may play a major role the Earth CPL-Cycles (Carbon-, Plate-, Life-Cycles).
Volcanoes are inherently complex and dynamic geological system, acting as the source of diverse sediment types and as a control on varied sediment transport processes within surrounding environments, both during and after their life. This can manifest as an accumulation of thick primary volcaniclastic sequences from pyroclastic (e.g. pyroclastic density currents, tephra falls), laharic and flank instability processes, secondary volcaniclastic sequences from the reworking/redeposition (or both) of primary deposits and their interaction with non-volcanic sedimentary processes, or deposits from the weathering of lava flows. The diversity of processes that may be involved in the generation of volcaniclastic sequences makes often difficult to describe and interpret them. As the comprehension of the generation, transportation and accumulation mechanisms of volcaniclastic sequences is of extreme importance for natural hazard and economic perspectives, to reduce uncertainties and move forward in the identification of volcano-sedimentary processes and potential effects, modern and ancient volcaniclastic sequences must be studied and interpreted hand in hand. Thus, the proposed session aims to bring together studies that explore the volcaniclastic record of modern and ancient environments. Contributions are welcomed in areas including, but not limited to, the identification of volcanic features in ancient sedimentary records, multidisciplinary (e.g., stratigraphic, petrographic, geophysical) approaches to the study of modern subaerial and submarine volcaniclastic sequences as analogue sites, and examples of the modification of sedimentary systems across syn- and inter-eruptive periods.
Volcanoes play an essential role in society through their impacts on human
life, infrastructure, and the environment. Those in marine settings pose
hazards, such as the awakening of submarine volcanoes, underwater
explosions, and sudden release of harmful gases from the volcano or
overlying water column, and tsunami inundation of neighboring coastlines
due to caldera collapse, submarine landslides, or entry of pyroclastic
flows into the sea. Specifically, volcanic degassing plays a dominant role
in forcing the timing and nature of volcanic unrest and eruptions in such
settings. On the other hand, quiescent passive degassing and
smaller-magnitude eruptions can impact the regional climate system. For
those reasons understanding the exsolution processes of gas species
dissolved in magma and measuring their emissions is crucial to
characterize the eruptive mechanism and evaluate the subsequent impacts on
the atmospheric composition, the environment, and the biosphere.
The session will be focused on multidisciplinary monitoring volcanic
environments, including in the vicinity of cities and highly touristic areas. Since
gas emissions are measured and monitored via in-situ and remote sensing
techniques, we invite contributions to studies that gain insights into the
subterranean-surface processes and quantify their impacts. In addition, we
encourage studies that focus on modelling the subsurface and
atmospheric/climatic processes and laboratory experiments that are
fundamental to the interpretation of field-based and satellite
observations. Finally, we will undoubtedly discuss the ability to
recognize the hazards and their impact on people, emergency management by
civil protection authorities, community education, case studies and risk
mitigation to reduce the effects of volcanism and its societal impact.
Developing physical-mathematical models able to describe the evolution of eruptive phenomena is a key point in volcanology. In the case of high-risk phenomena, such as lava flows or ash dispersal, predicting their spatial and temporal evolution and determining the potentially affected areas is fundamental in supporting every action directed at mitigating the risk as well as for environmental planning.
This session aims to address unresolved challenging questions related to complex geophysical flow modeling and simulation, gathering physical-mathematical models, numerical methods and field and satellite data analysis in order to: (i) expand knowledge of complex volcanic processes and their space-time dynamics; (ii) monitor and model volcanic phenomena; (iii) evaluate model robustness through validation against real case studies, analytical solutions and laboratory experiments; (iv) quantify the uncertainty propagation through both forward (sensitivity analyses) and inverse (optimization/calibration) modelling in all components of volcanic hazard modelling in response to eruptive crises.
Volcanic islands are simultaneously some of the tallest and fastest-forming geological features on Earth and constitute the site of significant geohazards ranging from volcanic eruptions, earthquakes, landslides, and tsunamis. Ocean island volcanoes are also some of the most enigmatic features in our planet, as their genesis is still not satisfactorily explained by conventional plate tectonics. The scientific community faces several challenges in studying volcanic islands, particularly in what regards processes taking place at depth. There is still a need to densify seismic networks in volcanic islands, using both land- and seafloor-based stations, to record the signals associated with volcanic and tectonic processes and automatically or manually detect and classify those signals. 3D images from the shallow crust to the deep mantle are crucial to unravel the geodynamic processes behind the generation of volcanism. More accurate quantification of temporal changes in the volcanic systems will help in the forecasting of potential eruptions and the monitoring of existing ones. On top of that, the presence of geothermal systems and induced seismicity from industrial exploration are also critical challenges in volcanic islands due to the system's complexity.
Considering the enormous diversity of interactions in volcanic islands, we welcome contributions from a wide range of studies including: seismo-volcanic monitoring and tracking of magma movements; characterization and location of volcanic tremor; 3D and 4D seismic imaging, including attenuation tomography; seismic ambient noise monitoring; machine learning to detect and classify volcanic earthquakes; active source studies to characterize volcanic flanks and landslides; induced and triggered seismicity in geothermal systems; and seismic sources.
The Phanerozoic has been punctuated by five mass extinctions and several major environmental perturbations, which were contemporaneous with massive volcanism and meteorite impacts. The session aims to gather researchers from geological, geophysical, and biological disciplines to highlight the recent advances of the causes and consequences of these environmental events. Therefore, contributions dealing with all aspects of the end-Ordovician, end-Devonian, end-Permian, end-Triassic, end-Cretaceous) and other related paleoenvironmental crises (e.g. the Paleocene-Eocene Thermal Maximum (PETM) and Oceanic Anoxic Events (OEAs) in the Mesozoic are welcome.
The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
The North-Atlantic-Arctic realm hosts vast extended continental shelves bordering old land masses, two Large Igneous Provinces (LIPs), one of which is the largest known sub-marine LIP (Alpha-Mendeleev Ridge) and a complex ocean spreading systems, including the slowest mid-ocean spreading ridge (Gakkel Ridge) and several extinct ocean basins.
Over recent decades, increasing scientific interest has led to the acquisition of vast quantities of geological and geophysical data across the North Atlantic-Arctic realm, yet our understanding of the region has become, if anything, even more controversial than it was before. The geodynamic and geomorphological processes acting here (and globally) are key to the understanding of the structure, geodynamic and paleolandscape evolution, hazards and resources in the region.
This session provides a forum for discussions and reviews of a variety of problems linked to the North Atlanitc-Arctic geodynamics such as plate tectonic, geodynamic, compositional, thermal, structural and landscape models, configuration of sedimentary basin and to propose additional experiments that can test these models. We welcome contributions from all relevant disciplines, including, but not limited to, plate tectonics, geophysics, geodynamic modelling, igneous, metamorphic and structural geology, palaeomagnetism, sedimentology, geomorphology, geochronology, thermochronology, geochemistry and petrology.
The Tethyan orogenic belt is one of the largest and most prominent collisional zones on Earth. The belt ranges from the Mediterranean in the west to Papua New Guinea in the east. It results from the subduction and closure of multiple basins of the Tethys Ocean and the subsequent collision of the African, Arabian and Indian continental plates with Eurasia. Its long-lasting geological record of the opening and closure of oceanic basins, the accretion of arcs and microcontinents, the complex interactions of major and smaller plates, and the presence of subduction zones at different evolutionary stages, has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and geodynamic processes with multiple disciplines. Advances in a variety of fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure and their physical and chemical characteristics, as well as the tectonics and geodynamic evolution of the Tethyan orogenic belt.
We welcome contributions presenting new insights and observations derived from different perspectives, including geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). In particular, we encourage the submission of trans-disciplinary studies, which integrate observations across a range of spatial and temporal scales to further our understanding of plate tectonics as a planetary process of fundamental importance.
The Arabian Plate recorded several plate reorganizations from the Neoproterozoic to present, including the Cadomian and Angudan orogenies, Late Paleozoic rifting and Alpine Orogeny. Active tectonics are framing the Arabian Plate and produce a variety of structures, including extensional structures related to rifting of the Red Sea and Gulf and Aden, strike-slip structures at the Dead Sea and Owen transform faults and compressive structures related to the Zagros-Makran convergence zone. The Arabian Peninsula contains the planet’s largest hydrocarbon reservoirs, owing to its geological history as Gondwana’s passive margin during the Permo-Mesozoic. Moreover, the Semail Ophiolite as the largest exposed ophiolite on Earth offers a unique example of large-scale obduction and overridden sedimentary basins. This and the spectacular outcrop conditions make the Arabian Peninsula an important and versatile study area. Ongoing research and new methods shed new light on, e.g., mountain building processes and its geomorphological expression as well as hydrocarbon development/migration.
We invite contributions that utilize structural, geophysical, tectonic, geochronological, geomorphological, sedimentary, geochemical/mineralogical, and field geological studies from the Arabian Peninsula and surrounding mountain belts and basins. These studies may include topics dealing with structures/basin analyses of any scale and from all tectonic settings ranging from the Neoproterozoic until today.
We invite contributions that address the present and past structure and dynamics of the Alpine orogens of the Mediterranean area. Since 2015, the international AlpArray mission and related projects have generated a plethora of new data to test the hypothesis that mantle circulation driving plates’ re-organization during collision has both immediate and long-lasting effects on the structure, motion, earthquake distribution and landscape evolution in mountain belts. Links between Earth’s surface and mantle have been forged by integrating 3D geophysical imaging of the entire crust-mantle system, with geologic observations and modelling to provide a look both backwards and forwards in time, the 4th dimension. This integrated 4D approach, initially focused on the Alps, has been expanded to the Pannonian-Carpathian and Adriatic areas, and now includes the Apennines and Dinarides. A new initiative, AdriaArray, is underway to shed light on plate-scale deformation and orogenic processes in this dynamic part of the Alpine-Mediterranean chain. The forthcoming Drilling the Ivrea-Verbano zonE (DIVE) project bridges new observations across scales and investigates the evolution of the continental lower crust. This session provides an interdisciplinary platform for highlighting the newest results and open questions of the aforementioned projects, regions and themes.
Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.
Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex (geo)chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy.
The aim of this short course is to is to give an overview on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags and resource recovery of valuable metals from slags. This short course is a follow up of a book entitled “Metallurgical Slags: Environmental geochemistry and Resource Potential” published in 2021 by the Royal Society of Chemistry and gives an overview useful for the environmental geochemists, geologists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.

After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.
