Session S-GC52: Volatile cycles in the Earth - from surface to deep interior
Volatiles play an important role in the dynamical and chemical evolution in the solid Earth. Rheological behavior of mantle rocks and mineral stabilities drastically change by the presence of volatiles. Chemical differentiation caused by partial melting and fluid transport is enhanced by volatiles. The hydrosphere has been maintained from the early Earth by balancing degassing from and regassing to the solid Earth. However, fundamental questions still remain, such as, amount and origin of volatiles in the mantle and crust, transport mechanisms of volatiles from Earth's surface to the solid interior, condition under which volatiles are stabilized in minerals from low to high pressure, influence of volatiles on physical properties of rocks and minerals, and volatile fluxes from the solid Earth to the surface through magmatism. Because these problems are tightly related with each other, we aim to have a discussion by integrating contributions from various fields such as geochemical measurements, geophysical observations, high pressure and temperature experiments, theoretical and modeling studies, all of which shed light on the cycles of volatiles, such as hydrogen, carbon, nitrogen, noble gases, halogens, and sulfur.
