The bedded manganese ore deposits of Shiraiwa Mine occur in andesitic breccia tuff of miocene age. The hypogene manganese minerals in the deposits mainly consist of pyrolusite and manganite with a small quantity of rhodochrosite. In the upper zones of the deposits, γ-type ramsdellite and part of pyrolusite are formed by the weathering of manganite. The alteration process of the mineral may be summarized as follows : [figure] The existence of two alteration processes of manganite is due to the difference in oxidation environments.
