Metallogeny of the uranium-bearing sedimentary basins

Abstract

The leading role of geochemical conditions in the formation of hydrogenous mineralization within the covers of young platforms has been shown. Tectonic regionalization of Central Asia for the recent time on the mobilistic basis has been accomplished, which has made it possible to characteriza the interrelations of individual large geological structures. The ore-bearing regions, which served as standard sites for modeling ore forming processes, have been distinguished. The whole spectrum of interrelations between ore-forming systems has been reduced to five typical models representing various geological and structural settings. The important achievement is a new method of prediction for the locations of uranium deposits of the sandstone group based on the compilation of series of paleohydrogeological maps on the paleotectonic base. It gives the possibility to predict deposit locations in different temporal shears under the complicated structural conditions in Neogene-Quarternary time.
