The characteristic features of the ores and electrum were obtained from results of field observations and laboratory studies of samples examined by ore microscope, electrical microscope photometer, microhardness tester, scanning electron microscope and electron probe microanalyzer.   The ores from the Matsuki ore deposits show much variation in modes of occurrence,textures,mineral and chemical compositions, and other properties, reflecting that they occurred in the marginal area of the basin away from the central area of acidic volcanic activity.   Electrum from the ore deposits crystallized at the late stage of the minerallization, and has many in common with mineralogical features of electrum from other stratabound ore deposits.   It is suggested that these data provide clues for a solution of the problems in the genesis and in ore-dressing and relining of the ores.}, pages = {425--439}, title = {最近開発された黒鉱鉱床の鉱石とエレクトラム : 松木鉱床}, volume = {7}, year = {1976} }
