Hyogo Prefecture has been known as one of prominent prefectures for metallic and nonmetallic mineral resources in Japan. There are variety of types of (1) metallic deposits and (2) non-metallic deposits in Hyogo Prefecture as shown below: (1) metallic deposits: polymetallic (Cu ・ Zn ・ Pb) vein deposits, Zn ・ Pb skarn deposits, bedded cupriferous pyrite deposits (Kieslager deposits), Au-Ag vein deposits, Ni deposits, podiform Cr deposits, bedded Mn deposits, Mo deposits and Fe skarn deposits, and (2) non-metallic deposits: strata-bound brick-silic astone (Keiseki) deposits, talc deposits, feldspar deposits, pottery stone (Toseki) deposits, and Roseki (pyrophyllite-, kaolin-, or sericite-clay )deposits. Especially, the Ikuno and Akenobe mining region has been famous as one of the largest and significant metallogenic regions in Japan and the large-scale Sn-W-bearing polymetallic vein deposits has been mined for copper, zinc, lead and tin. In this paper, location and type of ore deposit, geological setting, host rock of ore deposit, grade and constituent minerals of ore, metallogenic period and history of mining are briefly reviewed and summarized for each metallic and non-metallic mine in Hyogo Prefecture.
