Magmatic volatiles play a key role in the generation, transport, differentiation and eruption of magmas in various tectonic settings. Fluids from the subducting slabs and rising plumes drive magma generation in the mantle and control magma differentiation pathways and the formation of silicic plutons and magma chambers, and the consequent construction of the Earth's crust. Volatiles contribute to the formation of ore deposits and feed with mass and enthalpy hydrothermal systems that can potentially be exploited as geothermal energy resources. Volatiles are essential ingredients stimulating and maintaining magmatic and hydrothermal processes in the Earth's interior. This session fosters our understanding on: (1) the global volatile cycle in the Earth's lithosphere, atmosphere and hydrosphere and its contribution to plate tectonics; and (2) the control of volatiles on the chemical and physical aspects of magmatic processes shaping the Earth's interior. 

This session invites scientific contributions that investigate the role of volatiles on magma evolution using diverse techniques. We seek contributions from physical volcanological, and experimental studies; numerical and thermodynamic modeling; as well as work on the geochemistry of both volcanic and plutonic systems that address the generation and evolution of magmas and their tie to ore-deposit formation and geothermal reservoirs.
