At a time when it has been suggested that a large part of the resources of uranium available in readily accessible areas near the surface of the Earth may already have been found, and faced as we are by a demand which is likely to increase several-fold by the end of the century, it seems sensible to place any discussion of the geology of uranium on a very broad basis. No student of the Precambrian, and it is in this capacity that I speak, can fail to be fascinated by some of the remarkable discoveries made during the search for uranium deposits over the last four decades. The close connection, as Bowie has pointed out on more than one occasion (Bowie 1970, 1977), that exists between many deposits and the presence of Precambrian rocks in their vicinity, the general lack of deposits in the very oldest Precambrian and the irregular distribution both in space and in time of workable accumulations of uranium, are all findings which bear on the evolution of the crust. Almost certainly an understanding of such questions as these, thrown up by the work of the mining geologist and geochemist, will in turn make our comprehension of crustal evolution that much clearer. In the other direction, the very fact that uranium deposits are not distributed regularly through time and space suggests that there are some fundamental rules to be found, clues to which lie in our general knowledge of the geological history of the crust, particularly through the Precambrian.
