Investigating the magmatic processes that control the physical and chemical evolution of magmas within volcanic reservoirs is essential for quantifying pre- and syn-eruptive conditions. Magmatic processes, such as magma crystallization, magma mixing and degassing control magma differentiation and rheology, which in turn influence the remobilization of crystal mushes and cold magmas stored within the crust, the formation of eruptible magmas, magma ascent dynamics, magma fragmentation and eruptive behaviour. Understanding these processes and their timescales is, therefore, crucial for managing the environmental and societal impact of volcanic eruptions.
The textural, chemical, and isotopic characteristics of eruptive products can be used to elucidate the inner workings of magmatic plumbing systems, as well as constrain pre- and syn-eruptive processes. Similarly, analytical/field observations, laboratory experiments and numerical modelling are useful tools for the investigation of magmatic systems. This information is of paramount importance for policymakers in charge of mitigating the risks associated with volcanic activity.
In this session we welcome a wide range of petrological, geochemical, geophysical and volcanological studies, based on natural, experimental, and numerical-based approaches, with the scope of providing insight into the magmatic processes which occur both at depth and during ascent towards the surface. We also encourage contributions that investigate the mitigation of hazards associated with volcanic activity. Interdisciplinary works that consider the close and complex interplay between magmatic processes, conduit dynamics, eruptive behaviour, and emplacement mechanisms are of particular interest.
