Studies on the Molybdenum Deposits of the Daito District, Shimane Prefecture, Japan

The molybdenum deposits of the Daito district are located about 20Km southwest of Matsue city, Shimane prefecture, Chugoku province. The deposits under consideration are veins of mesothermal type, and now the most productive deposits of molybdenum in Japan. They are believed to have been formed in close relation to the granites distributed widely in this mining district.
