(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.

(1)研究了方铅矿、苏铁A、辉铋矿、水硼矿、黑罗夫斯基矿、伊利石、钾长石、伊利石等矿物科学。(2)本文报道了甲府花岗质岩石中各种类型矿床的K-Ar年龄。(3)根据HSAB原理，讨论了脉状矿床中金属的形态特征。(4)主要从矿物共生组合、硫同位素比值和流体包裹体充填温度等方面对矿床成因进行了探讨。（5）根据单斜辉石和闪锌矿的化学成分对矽卡岩型矿床进行了成因分类。(6)概述了希达和希达边缘带的矿床和地质。
