Research Abstract

In order to understand the chemical characteristics of aqueous fluids generated in subduction zones, and to know the role of such fluids in subduction zone phenomena, we have conducted in-situ chemical analyses of experimentally produced aqueous fluids and petrological investigations of natural metamorphic rocks. Through these researches, we have revealed that high-salinity fluids are being generated in subduction zones by metamorphic processes, and that those high-salinity fluids play critical roles in causing magmatism in volcanic arcs as well as seismic activities in subducting plate.
