Research Abstract

We conducted geological survey in Kamchatka, Russia, Kagoshima, Japan, and other regions in Southeastern Asia, mainly for hydrothermal deposits. We studied on hydrothermal alteration, mineralization stages, fluid inclusions, stable isotopes and mineral chemistry for descriptions of ore-deposits and revealing ore-forming conditions and process. Also we analyzed water-rock equilibrium temperature in underground and metal concentrations in hot-spring precipitates related to the geothermal activity in Kamchatka.
