| Session Description | The Asia-Oceanic region hosts some of the world’s most exciting and active volcanoes, situated around the ring of fire where eruptions often occur in zones of high population density. Volatile contents and composition play a fundamental role in the pressurization, ascent, and eruption of magma, as well as its quiescent degassing. We welcome contributions from studies of volatiles from pre-eruptive conditions to syn-eruptive degassing, and their application to understanding magmatic unrest, including but not limited to: (1) petrological-geochemical studies of melt and fluid inclusions, including volatiles recycling in subduction zones and primary mantle devolatilization, timing of separation and the mode of delivery of volatiles to the surface, and modeling of magmatic degassing and eruption processes; (2) volcanic and hydrothermal gas geochemistry, including volcanic gas geochemistry, gas-aquifer interactions, scrubbing and sequestration, volatile sublimation, atmospheric volcanic gas and aerosol chemistry and physics; (3) operational monitoring of volatile degassing (CO2, SO2, halogens, reduced species, noble gases, trace compounds) in plumes, fumaroles, hot springs, wells, and lakes; (4) novel instrumental and monitoring techniques, as well as multi-disciplinary approaches. Contributions to regional or local studies of Asia-Oceanic volcanic systems are particularly encouraged. |
