This session aims to probe questions such as how do we: 1) investigate transitions in volcanic eruption styles from melt and fluid inclusions, minerals, vesicles and glass in erupted products, 2) constrain magmatic processes that contribute to eruption explosivity such as volatile degassing and outgassing rates, kinetics of magma crystallization and bubble formation, rheology and fragmentation of magma, 3) detect magma bodies and determine their volume and geometry, 4) quantify time-integrated chemical, mechanical, and thermal processes in magmatic systems, 5) determine the frequency of magma injections, dykes, and melt extraction events, 6) interrogate minerals, glasses/melts, and volatile emissions, to constrain timescales and location of magmatic processes, and 7) decipher signs of volcanic unrest (e.g., degassing, tremors, edifice deformation). We invite contributions investigating the plumbing architecture and physicochemical evolution of magmatic systems, and measures to understand and forecast eruptions using field observations, laboratory analyses, experiments, numerical modeling, geophysical and geochemical techniques.
