| Research Abstract |
(1) Mineral sciences on galena, Joseite-A,bismuthinite, watanabeite, heyrovskyite, Iillianite, potosiite, incaite etc. have been studied.
(2) k-Ar ages of various types of deposits in the kofu granitic rocks have been reported.
(3) characteristics of metal species in vein-type deposits have been discussed based on the HSAB principle.
(4) Genetical considerations on ore deposits have been taken into, mainly based on mineral parageneses, sulfur isotopicratios and filling temperatures of fluid inclusions
(5) Genetic classification on skarn deposits has been made by chemical compositions of clinopyroxenes and sphalerites.
(6) Mineral deposits and geology of the Hida and Hida Marginal Belts have been summarized.
