V33D:
Chemistry, Mechanics, Geophysics, and Timescales of Magmatic Processes Posters


Submit an Abstract to this Session


Session ID#: 54000

Session Description:
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 ques

- 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/or melt extraction events

- interrogate minerals, glasses and melts, or volatile emissions, to constrain the timescales and location of magmatic processes

- decipher signs of volcanic unrest with respect to magmatic processes

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