TS11.1

Understanding the structure, architecture and tectonic evolution of a given region is of great importance to assess hydrocarbon prospectivity, since it provides significant informations on: heat-flow, the geometry and timing of accommodation space, the trap type and its activity.
The session aims at showing how different geophysical prospecting methods can be applied in structural geology and tectonics in order to obtain the best possible models that
allow to:
- better define and assess the exploration potential of specific regions, based on their tectonic history.
- understand and construct tectonic and structural models for a given area.

TS11.2

Geological models are key to our understanding of the subsurface by providing both visual and quantitative context. But accurately modeling the significant heterogeneities, discontinuities and the uncertainties of geological systems from often sparse data remains challenging. Substantial developments in geomodeling over the past years has helped bridge the gap between input data and resulting geomodel, allowing for the (semi-)automated construction of geomodels, a quicker model validation and rebuilding when new data arrives, as well as an efficient testing of multiple hypotheses. Increasing computing power now also allows for effective stochastic simulation of uncertainties in geomodeling, as well as the integration of probabilistic inference frameworks and geophysical inversions. Machine learning approaches can be used in every step of the geomodeling pipeline to enhance the process: from automated input data extraction and classification to probabilistic model selection.

We seek here contributions from all geoscientists using 3-D geological modeling methods, as well as novel developments to construct these models, to quantify and communicate uncertainties, highlighting existing challenges and future developments, including integrating geological modeling into geophysical inversions. Of special interest are also approaches to combine and enhance geomodeling with machine learning methods. Applications can be in any field of solid earth sciences to address scientific questions throughout the lithosphere or anthroposphere.

TS11.3

Seismic data analysis and interpretation is the key tool enabling the unravelling of the geometry and evolution of subsurface geology.
In the last decades, significant improvements in the acquisition and processing techniques have been combined with a growing coverage of high-resolution and broadband frequency seismic data, including the public release of large volumes of 2D-3D hydrocarbon industry-sourced data. This led to shedding genuine new light on the subsurface geology of large portions of the Earth’s continental margins, and enabled improved quantitative rock property parametrization.
In addition, seismic reflection data have recently appealed to an ever-growing scientific audience, including exploration geoscientists, marine geologists, seismic geomorphologists, stratigraphers and structural geologists. This growing community has been collectively working towards the integrated application of seismic interpretation techniques, including seismic attribute analysis, for industrial purposes as well as for environmental and academic research studies.
In this fast-developing context, it is fundamental to share the knowledge between different research and application approaches. Therefore, the aim of this session is to provide the state-of-the-art and new prospective in seismic data analysis and quantitative subsurface characterization for structural geology and tectonics, but also for exploration seismology, marine geology, seismic geomorphology, stratigraphy, etc.
We thus invite submissions that aim to present new insights in the seismic interpretation of: i) shallow high-resolution seismic data; ii) deep industrial subsurface data (e.g., for hydrocarbon exploration); and iii) ultra-deep lithospheric seismic data. Studies integrating different approaches and disciplines are particularly welcomed.

GD4.2

International Lithosphere Program (ILP) has since 1980 been initiating major international, multidisciplinary research programmes to elucidate the nature, dynamics, origin and evolution of the lithosphere. ILP has taken initiative to more than 70 programmes within its four research themes: (1) Geoscience of Global Change, (2) Contemporary Dynamics and Deep Processes, (3) Continental Lithosphere and (4) Oceanic Lithosphere. Example programmes initiated by ILP include World Stress Map, Global Strain Rate Map, Global Seismic Hazard Assessment Map, Seismic Hazards and Megacities, Global Impact project, International Continental Drilling Program (ICDP), and a series of Global Geoscience Transects and programmes. Present programmes focus on integrated mapping of lithosphere physical parameters, lithosphere dynamics including the fate of subducted lithosphere and deformation of continental lithosphere, response of the lithosphere to surface processes including changes in climate and erosion/deposition dynamics, mineral resources, and seismic risk. ILP promotes high class science in combination with community services through the Evgueni Burov medal for mid-career scientists and the Flinn-Hart Award for outstanding early-career scientists, which are awarded during the UGU annual meeting. The activities of ILP seeks to achieve a balance between: "addressing societal needs" in regard to e.g. natural catastrophes, resource exploration and environmental protection; and "satisfying scientific curiosity" in regard to global and regional processes affecting the lithosphere. This symposium presents some of the ILP activities.
In particular, we invite, in particular multidisciplinary, contributions which focus on the structure and evolution of the continental crust and upper mantle and on the nature of mantle discontinuities. The latter include, but are not limited to, the mid-lithosphere discontinuity (MLD), the lithosphere-asthenosphere boundary (LAB), and the mantle transition zone, as imaged by various seismological techniques and interpreted within interdisciplinary approaches. Papers with focus on the structure of the crust and the nature of the Moho are also welcome. Methodologically, the contributions will include studies based on seismic, thermal, gravity, petrological, and/or electro-magnetic data interpretations.

Confirmed invited speakers: Sierd Cloetingh, Harsh Gupta, Sergei Lebedev and Taras Gerya.
