Session 4a – Magma transport, storage, and mineralisation in volcanic systems across tectonic settings
Large-scale volcanic eruptions pose significant global hazards, which can have far-reaching societal and economic consequences. The ongoing unrest at the Campi Flegrei caldera in Italy highlights the critical need for a thorough understanding of magmatic processes within volcanic plumbing systems and the dynamics governing magma ascent and eruption at calderas.
Processes involved in the formation, growth, and eruption of expansive transcrustal magmatic systems operate over a spectrum of spatial and temporal scales, involving complex geologic and petrologic dynamics. These processes play a fundamental role in influencing the timing and style of volcanic activity. Evidence for understanding such caldera-forming systems and their eruptive processes comes from geological, petrological, geophysical, experimental, and modelling studies.
Establishing links between magma dynamic processes across different scales within large transcrustal plumbing systems and during eruption is crucial to forecast their evolution over time and towards potential caldera-forming events, and consequently to providing more accurate hazard and risk assessment. Therefore, this session cordially invites cross-disciplinary contributions focusing on the physical, chemical, and temporal evolution of magmatic plumbing systems that lead to caldera-forming eruptions using diverse techniques such as field, geophysical or geodetic observations, theoretical or analytical models, petrological and geochemical constraints, and experimental or numerical methods. We also welcome scientific findings that contribute to a better characterization of eruptive processes and the hazards and risks of potential caldera-forming systems.
This session is co-sponsored by the IAVCEI commissions of Collapse Calderas and Volcanic and Igneous Plumbing Systems.
