1 INTRODUCTION. Manganese mineralization is widespread in the Birimian greenstone belts of Ghana, part of the province of the West African craton (Kesse, 1976).According to Leube, Hirdes, Mauer, and Kesse and Melcher (), manganese-rich chemical sediments tend to occur in transition zones between belt volcanics and basin sediments.In the …

Petrological significance of manganese carbonate inclusions in spessartine garnet and relation to the stability of spessartine in metamorphosed manganeserich rocks. Contrib.
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 …

At least 15 manganese deposits crop out in the West African craton in Mali, Burkina Faso, Ghana and Cote d'Ivoire. There average grade estimates range from 17 to 52% total Mn oxide and average volume of 5–19 Mt of ore; they consequently provide an attractive target for exploration and eventual exploitation.The Tambão and Béliata Mn oxide deposits in the …
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.
Simplified stratigraphic section of the lower Proterozoic Nsuta manganese deposit, Ghana, showing the position of Mn carbonate-bearing micronodules. The intraclastic rocks (which also contain micronodules) may actually grade into laminae containing only Ca–Mn micronodules. Inset is map of Africa showing the position of Ghana.
Carbon and oxygen isotope analyses of manganese-bearing carbonates from the Palaeo-Proterozoic Nsuta manganese deposit, Ghana, suggest important relationships between isotopic composition of the Mn-bearing carbonates and lithology, locality and carbonate microfacies.
