Outline of Final Research Achievements

Kaizuki-yama granite, which intruded into the Jurassic Mino terrane, were estimated using conventional geothermobarometers, and a possible cooling process of the body was proposed. Calcic plagioclase (up to An90) was commonly occurs in the granite, and is consider to show evidence for assimilation of limestone and/or skarn in country rocks during intrusion of acidic magma.
(2) Exhumation rate of low-pressure/high-temperature type Ryoke belt was discussed based on petrological and mineralogical studies of granitoids and their surrounding metapelites. The “Kamihara tonalite”, one of the oldest intrusive bodies, is separated into two groups considering their forming conditions.
