GMPV7.2: Architecture and Dynamics of Volcanic and Igneous Plumbing Systems
23 Apr 2023 – 28 Apr 2023
Location: Vienna, Austria
Main Event: GMPV7.2: Architecture and Dynamics of Volcanic and Igneous Plumbing Systems
In the last few decades, the ideas on the architecture and evolution of volcanic and igneous plumbing systems (VIPS) were profoundly modified. The classical paradigm of the magma reservoir as a large and long-lived liquid-rich region slowly fractionating has been challenged by the view of liquid-poor crystal mush that is repeatedly rejuvenated over the lifespan of the magmatic system.
Recent research applying various methods to study plumbing systems have shed light on this complexity. The existence of trans-crustal magmatic systems in which multiple and ephemeral magma chambers develop within a volumetrically dominant mush system has been postulated.
Developing a comprehensive model of magma storage and ascent in these complex systems is of paramount importance as these processes exert essential control on both the evolution of precursory phenomena recorded during volcanic crises as well as the style and intensity of the impending eruption.
Many questions remain as areas of active research and debate:
- How do plumbing systems develop? How do they evolve over time and in different tectonic settings?
- What are the triggering mechanisms for volcanic eruptions in these systems (e.g., magma reservoir vs mush system)?
- How do magma ascent and dyke propagation occur? Do they occur differently in mush systems?
- What do current monitoring techniques tell us about plumbing systems and precursory phenomena of magma ascent and eruption?
This session aims to bring together scientists working in different fields of igneous petrology and geochemistry, structural geology, geodesy, and geophysics. Studies using different methods such as field studies, compositional and textural analyses, laboratory experiments, numerical/analogue modelling, and seismic and ground deformation surveys to understand the architecture and dynamics of VIPS are the core of this session. We, therefore, invite contributions highlighting insights from one of these fields and highly encourage contributions using multi-disciplinary approaches.
This session is sponsored by the IAVCEI Commission on Volcanic and Igneous Plumbing Systems and will be convened by Gianmarco Buono, Joana Martins, Fabien Albino, Catherine Annen and Lucia Pappalardo.
The abstract submission deadline is 10th January 2023, 13:00 CET. Please click here for more information.
