V33E:
Quantifying Storage, Transport, and Volumes of Magmas in the Earth's Crust I


Session ID#: 9804

Session Description:
When, where and for how long magmas are stored within the Earth and how they contribute to the crustal chemical, physical and thermal architecture remain important challenges in geosciences. Magmatic bodies have been detected with a wide range of geophysical approaches; however, the volumes, mechanics, chemical signatures and evolution of these bodies remain poorly constrained. We seek contributions that utilise field, numerical and experimental methods to address the following key themes: (i) how do we detect magmas bodies and do we determine their states and volumes in the Earth's crust, (ii) how can we quantify chemical, mechanical and thermal processes that operate within those volumes, (iii) what can minerals, glass/melt and volatile emissions tell us about timescale of magmatic processes constructing the architecture of the continental crust, volcanoes and atmosphere. This session aims to foster cross-disciplinary interactions and collaborations between field geologists, geochemists, petrologists, volcanologists, geophysicists, and numerical modelers.
