Extensive beds of carbonaceous shale occur within a thick sequence of Lower Proterozoic dolostone, the lower Transvaal Supergroup of South Africa. The shale contains such high concentrations of A12O3 (21.9%) and K2O (6.5%) that it is compositionally

Present models of the derivation of the gold in the Witwatersrand conglomerates of South Africa as detrital grains directly from primary deposits in a source area consisting mainly of Archaean schist belts meets with a volume problem. Witwatersrand d
