Revealing the volumes, mechanics, chemistry, and temporal evolution of magma bodies in the Earth’s lithosphere, and how they contribute to its architecture and dynamics requires integration of multiple types of observations, and cross-disciplinary collaboration among geologists, geochemists, petrologists, geochronologists, volcanologists, and geophysicists. We aim to bring together researchers from across these disciplines to probe questions such as how do we:

• detect magma bodies and determine their volume and geometry
• quantify time-integrated chemical, mechanical, and thermal processes
• determine the frequency of magma injections, dykes, and melt extraction events
• interrogate minerals, glasses/melts, and volatile emissions, to constrain the timescales and location of magmatic processes
• decipher signs of volcanic unrest with respect to magmatic processes.

We encourage researchers that study magmatic processes using field studies, geophysical observations, laboratory analysis, modelling, and/or experimental simulations on any scale to submit contributions to this session.
