Outline of Final Research Achievements

The 1707 pyroclasts of Mt. Fuji have gabbroic xenoliths. we studied fO2 conditions of the gabbroic xenoliths in order to understand a redox state within magma chamber of an island-arc volcano. Fe-Ti oxides thermobarometry-oxybarometry yield T-fO2 conditions of ca.760-940 degree C and near Ni-NiO buffer for ilmenite-magnetite coexisting samples.
