V43C:
Transport of Volatiles from Mantle to Surface: Insights on Diffusion, Exsolution, and Migration of Fluids in Magmatic Environments from Natural Samples and Experiments I Posters


Session ID#: 11048

Session Description:
The transfer of volatiles (H2O, CO2, Cl, S, F) between reservoirs within the mantle, subducted oceanic crust and continental crust 1) influences magmatic processes, 2) modifies trace element and isotope signatures and 3) may change redox conditions. The physical and chemical properties of magmas are significantly influenced by diffusion and exsolution of volatiles during their ascent from the upper mantle through the crust to the surface. For instance, magma degassing may initiate volcanic eruptions, modulates magma viscosity (especially along the conduit) and, thus, affects the eruptive style. This session seeks insights from natural and laboratory observations involving volatile transfer and degassing. Cross-disciplinary studies (e.g. petrology with geophysics and/or geochemistry) providing temporal constraints, and/or involving volatile solubility, fluid and melt composition, isotope signatures and redox conditions are especially welcome.
