V34B:
Origin and Timescales of Magmatic Systems: Discussing Ages, Rates, Transport, and Storage Processes of Magmas from the Source to Emplacement or Eruption II


Submit an Abstract to this Session


Session ID#: 59372

Session Description:
Magmatic systems involve a range of dynamic processes governing magma generation, ascent, emplacement, and eruption. The timescales of these processes are of paramount importance to understand the evolution of magmatic reservoirs and mush zones during crystallization, assimilation, mixing, and volatile exsolution. Depending on the ascent timescales, these processes may operate far from compositional and textural equilibrium, induced by rapidly changing environmental parameters (e.g. P,T,fO2). Rates and mechanisms of crustal emplacement or eruption, together with physical, petrological and rheological investigations of magmas, are also crucial in characterizing volcanic hazard. We welcome analytical, numerical, experimental, geophysical, and field-based studies addressing rates and timescales of magmatic processes, within the Earth and other planetary bodies. These may include radiogenic isotope dating, mineral geospeedometry, crystal size distribution, and fluid dynamics. Also, we welcome interdisciplinary studies probing the mechanisms and timescales of volcanic phenomena like pre-eruptive dynamics, magma and lava rheology, phase equilibria, and volcanic flows.
