THE MODE OF OCCURRENCE AND THEORY OF ORIGIN OF THE URANIUM MINERALS AND GOLD IN THE WITWATERSRAND ORES
Technical Report
·
OSTI ID:4262154
The gold--uranium ores of the Witwatersrand goldfields consist mainly of compact metumorphosed conglomerates occurring as bands in a thick body of sediments spread laterally over a vast area. These sediments consist predominantly of quartzites. The conglomerate consists mainly of pebbles of vein- quartz cemented by a fine-grained matrix composed principally of quartz and phyllosilicates. The valuable constituents are almost entirely confined to the matlix of the conglomerate, the pebbles of quartz being virtually barren. Some uranium and gold are present in banded pyritic quartzites occupying erosion channels cutting the bands of conglomerate. (auth)
