Genetic Types, Classifications, and Models of

2017-1-1  The possibility of catagenetic manganese ore-formation in connection with the Mangyshlak and Laba deposits has been expressed by V.N. Kholodov, V.I. Dvorov, and E.A. Sokolova. In this case, petroleum waters contain large quantities of carbon dioxide, methane, hydrogen sulfide, and other aggressive components.

Geology and ore genesis of the manganese ore

The Postmasburg Mn/Fe-ores occur exclusively in dolomitic Precambrian sinkhole structures with siliceous breccias and shales as hostrocks. The main manganese minerals are braunite and bixbyite, apart from secondary alteration products of the psilomelane-manganomelane family. Various generations of ore minerals could be identified. The ore mineralization is subdivided into three different ...
