Scope 
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 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.
