oa Botswana Notes & Records - The Kgwakgwe Manganese Oxides in the Kanye Area, Southeastern Botswana - Evidence for a Shallow Aqueous Palaeo-Environment

Volume 30, Issue 1
  • ISSN : 0525-5090



The geology and mineralogy of manganese oxide nodules occurring in the manganiferous shale horizon of the Kgwakgwe Shales of the lower Transvaal Supergroup (about 2500 million years old), in the Kanye area, are studied to elucidate their genesis. Evidence of the rhythmic layering of white Kaolin clay and black manganese and iron oxides support a genetic association of the shales to a low energy lagoonal or lacustrine environment of deposition. Both the Kaolin and manganese oxide laminae are of syngenetic origin.
