| 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.
