South Africa is one of the countries with the richest gold ore resources in the world.The gold deposits mainly occur in the northeast of the South Africa.Three types of gold ores have been recognized,which are: ① Witwatersrand conglomerate type gold deposits; ② granite greenstone belt type gold deposits; and ③ dolomite type gold deposits,with the former two types being the major ones in the region. Witwatersrand conglomerate type gold deposits are high grade,maximum deposits yield, large scale and very depth and are the most important types in South Africa.The genesis of the deposits is controversial.Two different models occur which include placer mode and thermal fluid model.According to the current data the writers think they represent two different mineralization stages. Granite greenstone belt type gold deposits mainly occur in the Barberton area which are large scale, easy mining and other characteristics, therefore which occupies an important position in the South African. The deposits are mainly hosted in quartz veins or shear zones. Three different models occur which include volcanogenic mineralisation models, inverted decollements modes and structure intersection model.
