  • Witwatersrand Wikipedia

    The Witwatersrand Basin is a largely underground geological formation which surfaces in the Witwatersrand It holds the world's largest known gold reserves and has produced over 15 billion ounces (over 40,000 metric tons), which represents about 22% of all the gold accounted for above the surface The basin straddles the old provinces of Transvaal and the Orange Free State, and consistsSouth Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore and gold could not be extracted from this compound with any of the then available technologies John Stewart MacArthur and the Dingus brothers overcame this by suspending the crushed ore in a cyanide solution Separation of up to 96% pure gold was achieved which led to an investment boom asBrief history of gold mining in South Africa Mining forSouth Africa South Africa Gold mining: Prospectors established in 1886 the existence of a belt of goldbearing reefs 40 miles (60 km) wide centred on presentday Johannesburg The rapid growth of the goldmining industry intensified processes started by the diamond boom: immigration, urbanization, capital investment, and labour migrancy By 1899 the gold industry attracted investment worthSouth Africa Gold mining | Britannica

  • On the source of orogenic gold | Geology | GeoScienceWorld

    The vast majority of orogenic gold (excluding Witwatersrand, South Africa) is from three periods in geologic time: the Neoarchean (ca 27002400 Ma), a second period in the Paleoproterozoic (ca 21001800 Ma), and a third period from ca 650 Ma continuing throughout the Phanerozoic (Goldfarb et al, 2001)Two explanations have been offered for this timing: (1) because orogenic gold deposit· The Transvaal Supergroup is located in the Transvaal Basin in South Africa, and rests on the northern and western parts of the Kaapvaal Craton ()The Black Reef Formation is the basal lithostratigraphic unit of the late Archean to early Proterozoic Transvaal Supergroup (Els et al, 1995)It lies unconformably on the volcanosedimentary rocks of the Ventersdorp Supergroup and theThe origin of the gold and uranium ores of the Black ReefGeologic map of the Banqi gold deposit, showing the domal shortaxial anticline structure that controls ore called the Naban fold 1,2the Permian rocks (P1, P2); 3the Triassic Ziyun group rocks (T1Z); 4, 5, 6the Triassic Xinyun group rocks (T2X2, T2X3 and T2X4); 7t he gold orebody; 8Axis of shortaxial anticline; 9fault Modified from Pu, Hanke (1987); and Liu, DS (1994) ApproximateGEOLOGY OF SEDIMENTARY ROCKHOSTED GOLD DEPOSITS
