Scope Fluids from the subducting plates play vital roles in subduction zone magma genesis, earthquake mechanism, etc. In this special session, we aim to discuss the role of fluid in subduction zone phenomena integrating various research fields, e.g., geophysics, geochemistry, petrology, high-pressure experiments, numerical simulation, environmental geology, hydrology, resources geology,etc.
