[S-CG16] Deep Carbon Cycle

Thu. May 28, 2015 2:15 PM - 4:00 PM 201A (2F)

Convener:*Yuji Sano(Division of Ocean and Earth Systems, Atmosphere and Ocean Research Institute, University of Tokyo), Hiroyuki Kagi(Geochemical Laboratory, Graduate School of Science, University of Tokyo), Eiji Ohtani(Department of Earth and Planetary Materials Science, Graduate School of Science, Tohoku University), Chair:Yuji Sano(Division of Ocean and Earth Systems, Atmosphere and Ocean Research Institute, University of Tokyo), Hiroyuki Kagi(Geochemical Laboratory, Graduate School of Science, University of Tokyo), Eiji Ohtani(Department of Earth and Planetary Materials Science, Graduate School of Science, Tohoku University)

Volatiles including carbon and hydrogen have strong impacts on various phenomena, such as material and geochemical circulations in global earth, and mantle convection and dynamics of the earth's interior and deep life. We welcome contributions on volatiles in the earth from wide range of disciplines such as geodynamics, volcanology and petrology, mineral physics, isotope geochemistry, and bio-geoscience.
