  • The rhodochrosite ores in black shale basins are usually occupied by a large quantity of pyrites, cause the deposit processes of rhodochrosite and pyrite are hard to observe directly, the enrichment relationship of them is not clear currently. To study the correlation between them, this research selected typical profile of Xixibao manganese ore in northeast of Guizhou province as example. It is based on ordinary thin section, TOC analyses and elemental analyses, which analyzed lithological sequence, mineral assemblage and the geochemical characteristics of Mn and Fe in the manganese-bearing rock series and the roof and floor of them, and at the same time carried out comparison analyses with modern rhodochrosite deposit. Reaearch showed that the Xixibao manganese ore did share some similar characteristics with that of modern Baltics Sea on the enrichment relationship of pyrite and rhodochrosite. The Mn content is low in both roof and floor of the manganese-bearing rock series; inner the manganese-bearing rock series the Mn content fluctuated greatly and is negatively correlated with the Fe content. The precipitation of pyrite and rhodochrosite has a sequence, usually the pyrites are precipitated first from the solution and followed by rhodochrosite.

Abstract: The rhodochrosite ores in black shale basins are usually occupied by a large quantity of pyrites, cause the deposit processes of rhodochrosite and pyrite are hard to observe directly, the enrichment relationship of them is not clear currently. To study the correlation between them, this research selected typical profile of Xixibao manganese ore in northeast of Guizhou province as example. It is based on ordinary thin section, TOC analyses and elemental analyses, which analyzed lithological sequence, mineral assemblage and the geochemical characteristics of Mn and Fe in the manganese-bearing rock series and the roof and floor of them, and at the same time carried out comparison analyses with modern rhodochrosite deposit. Reaearch showed that the Xixibao manganese ore did share some similar characteristics with that of modern Baltics Sea on the enrichment relationship of pyrite and rhodochrosite. The Mn content is low in both roof and floor of the manganese-bearing rock series; inner the manganese-bearing rock series the Mn content fluctuated greatly and is negatively correlated with the Fe content. The precipitation of pyrite and rhodochrosite has a sequence, usually the pyrites are precipitated first from the solution and followed by rhodochrosite.
