Scope 
Fluids are key drivers of dynamic Earth processes, controlling the transfer of mass, energy, and elements across the crust and mantle. They strongly influence earthquakes, volcanism, metamorphism, and ore formation. This session aims to bring together cutting-edge studies that reveal how fluid circulation, fluid-mediated reactions, and mass transport operate from the shallow crust to the deepest subduction zones. We will highlight fluid-rock interactions across various scales from microstructural processes to plate-scale dynamics and discuss their role in shaping global geochemical cycles, surface environments, and tectonic activity. We especially encourage contributions that explore recent advances in studies on roles of fluid on earthquakes, element transfer in subduction environments, mineralization, serpentinization, carbonation, and geothermal systems. Studies that emphasize interdisciplinary approaches, integrating field observations, laboratory experiments, high-resolution geophysical monitoring, and state-of-the-art numerical modeling, are particularly welcome. By fostering dialogue across these approaches, this session seeks to advance our understanding of how fluids govern evolution and dynamics of the Earth.
