Session ID#: 18201

Session Description:
When, where, and for how long magmas are transported and stored within Earth’s crust domain in different tectonic settings are key questions in geosciences. Unravelling the internal structure and dynamics of Earth’s crust means investigating the different geochemical, mechanical, and thermal combinations that control the dynamics (i.e. magma transport, emplacement, storage, and fluxes) and internal geometries (i.e. pluton/chamber/reservoir volumes and distributions) within Earth’s crust. We welcome field geologists, geochemists, petrologists, volcanologists, geophysicists, and numerical modellers who utilise field, numerical, and experimental methods to address the following key questions:

(i)         How do we detect magmatic bodies? How do we determine their status and volume in Earth's crust?

(ii)       How can we quantify the chemical, mechanical, and thermal processes that operate within those volumes?

(iii)      How can we determine the frequency of magma injections/pulses in Earth’s crust? What is the architecture of dyke and plumbing systems feeding volcanoes?
