The work would not have been possible without mine access and research projects involving 40 Witwatersrand gold mines. Many people have debated and refined our ideas on Witwatersrand gold genesis; and Russell Myers, Jonathan Law and Andy Barnicoat are thanked especially for sharing their insights into the roles of the thrust faults, gold grains, quartzites and sedimentology. MartinHughes is thanked for his significant input to our understanding of Palaeozoic slate belt and gold placer systems; and Iain Pitcairn for his comments on the manuscript. Figures are taken from geology of gold courses with permission. Metamorphic and alteration studies were supported by the Richard Ward Endowment Fund from University of Witwatersrand, Key Centre for Economic Geology in Townsville, Gencor Mining Corporation, Great Central Mines Ltd, and CSIRO.
