The Nsuta Manganese Deposit — Ghana | SpringerLink

This relatively simple deposit illustrates the way manganese oxide Minerals can accumulate in a laterite profile. The manganese originated as a metamorphosed manganiferous sediment; quite unworkable in itself, but which has been concentrated on an old erosion surface, and which also carries ferruginous and aluminous laterites.

The manganese deposit of Nsuta, in the Ashanti Belt of Southern Ghana, is sandwiched between Birimian metasedimentary rocks. The metasedimentary rocks contain interbedded carbonate-rich layers, which exhibit a characteristic banded appearance near the contact with the orebody. The orebody is a carbonate-type manganese-formation and in terms of origin is considered here as a Mn-analogue of

Oxygenation of the atmosphere and oceans has influenced the evolution of ocean chemistry and diversification of early life. A number of large manganese (Mn) deposits are distributed in the Paleoproterozoic sedimentary successions that were formed during the great oxidation event (GOE) around 2.4-2.2 Ga (Meynard, 2010). Due to the high redox potential of Mn, occurrences of Mn deposits

Spessartine Garnets in a Manganiferous Carbonate

The Nsuta manganese deposit occurs within the Birimi-an of Ghana. Major aspects of both the regional geology and the geology of the deposit are reported in Service (1943), who also noted a major anticlinal structure, with subsidiary synclines and anticlines, at the Nsuta deposit. Recent fieldwork by one of the authors (F. K. N.) seems

The manganese deposits of the Guiana shield | Semantic

Microscopic and x-ray studies of manganese minerals from 15 deposits provide the basis for classification into spessartite, rhodochrosite, and braunite protores, together with their residual and lateritic derivatives. The most important minerals are pyrolusite-polianite, cryptomelane, and lithiophorite. Chalcophanite, manganite, and braunite are less common.
