[S-CG58] New Developments in fluid-rock Interactions: From Surface to Deep Subduction Zone

Sun. May 21, 2023 3:30 PM - 4:45 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Atsushi Okamoto(Graduate School of Environmental Studies), Jun Muto(Department of Earth Sciences, Tohoku University), Ikuo Katayama(Department of Earth and Planetary Systems Science, Hiroshima University), Junichi Nakajima(Department of Earth and Planetary Sciences, Tokyo Institute of Technology), Chairperson:Junichi Nakajima(Department of Earth and Planetary Sciences, Tokyo Institute of Technology), Atsushi Okamoto(Graduate School of Environmental Studies)

Fluid circulation and fluid-mediated reactions and mass transport in the Earth's interior govern active phenomena within crust and mantle, such as earthquakes, volcanism, metamorphism, and formation of ore deposits. In this session, we will discuss the micro- to field-scale fluid-rock interactions related to chemical reactions, mass transport, deformation from near-surface to deep subduction zone, and their impact on global elemental cycles, surface environments and seismicity. Recent progress of various studies on fluid-rock interactions in geothermal systems, mineralization, serpentinization, carbonation, metamorphism and metasomatism in deep subduction zones are welcome. We would like to comprehensively discuss the impact of these processes on global element cycles, surface environments and seismic activities. We welcome research from various approaches such as field studies, laboratory experiments, geophysical observations, numerical simulations.

4:30 PM - 4:45 PM
