A bedded sedimentary manganese deposit, consisting originally of rhodochrosite, quartz, chlorite and pyrite, was intensely metamorphosed by a granite pluton, resulting in a metachert-hosted pyroxmangite-garnet-amphibole manganese ore, cut by molybdenite-bearing quartz veins.
Fe, Co, Ni, Cu, Zn, As, Te, Pb, Bi, traces of which had originally been scavenged from seawater by manganese oxides, are now present as native elements, sulphides, arsenides or tellurides.
