| Abstract: | Recently contact metasomatic zone and massive ore bodies were found in the manganese epithermal deposits of the Jokoku mine. Various kinds of contact minerals occur in the contact metasomatic zone which is formed by replacement of the Palaeozoic limestone. The massive ore bodies also formed by replacement of the limestone. These ore bodies are made up of carbonate ore consisting predominantly of rhodochrosite, associated with dolomite, calcite, kutnahorite and small amount of sulphide minerals. The parts of the Jokoku mine studied here belong to the metasomatic deposit type, which has been influenced by early hydrothermal solution. |
