Abstract
The principal mineral deposits of Proterozoic age in Australia, not only of uranium but also of base and precious metals, are found within a north-trending belt central to the continent which stretches from Adelaide to Darwin. This belt represents the margin to the West Australian Archaean craton, and comprises orogenic and shelf domains that evolved throughout the Proterozoic; and it is suggested that the formation of the uranium deposits was an integral part of the evolution of the various geosynclines in the belt. The uranium ore bodies occupy structurally prepared features such as shears, faults and breccias, and are clearly introduced, but the source of the mineralizing fluids, and the precise mechanism of deposition, is, in some cases at least, in dispute. Mineralization per ascensum by connate water carrying metals desorbed from the sedimentary pile, or in association with acid magma which may itself be the product of anatexis, is favoured by the author.
