mining breccia in postmasburg manganese ore field

Jun 01, 1995· Abstract. ThePostmasburg Mn/Fe-oresoccur exclusively in dolomitic Precambrian sinkhole structures with siliceousbrecciasand shales as hostrocks. The mainmanganese mineralsare braunite and bixbyite, apart from secondary alteration products of the psilomelane-manganomelane family. Various generations ofore mineralscould be identified.
