A strategy for uranium exploration in the Permo-Triassic Beaufort Group of the main Karoo basin, South Africa

Le Roux J.P. ; Brynard H.J. (1994)


An abundance of data accumulated over the last decade provides new insights into the genesis of uranium deposits in the Beaufort Group. An exploration strategy is proposed which is based on the known regional and stratigraphic distribution of uranium, geochemical data, the possible influence of syn-and post-sedimentary tectonics, as well as sedimentological and diagenetic controls. Regional target areas most likely to host uranium ore-bodies can be identified using the above information along with the regional and stratigraphic distribution of host sandstones and source materialsas well as the regional fluid migration patterns. This is followed by the delineation of local targets where areas of sandstonescoalescence and palaeocurrent directions are particularly useful. © 1994.
