摘要
The Moeng manganese ore deposit in Botswana, formed in Proterozoic Era, is closely associated with iron-bearing formation. Based on the regional geological background and geological features, this paper analyses the lithofacies palaeogeography of this area, and suggests that this manganese ore deposit was formed in a continental shelf deposit environment. Accordingly, a genetic model is established for this ore deposit, and a view of point is proposed that it is a neritic sedimentary metamorphic manganese deposit. The comparison between the Moeng manganese ore deposit and the Kalahari manganese ore field, the largest in the world, shows that these two manganese ore deposits have similarities in metallogenic background, metallogenic age, ore deposit features, lithofacies palaeogeography, and epigenetic modification. It is thus concluded that the Moeng manganese deposit has a potential of search for manganese ore to become a large-scale mine.
