On the basis of long-term investigations and literature analysis it is concluded that voluminous cataclasites are spatially and genetically associated with the alkaline sodium metasomatism process. The cataclasites were formed in the zones of long-living Meso-proterozoic breaks as a result of fluid-explosive phenomena occurring in the upward fluxes of plutonic alkaline uranium-bearing solutions. Peculiarities of deformations and spatial disposition of ore-bearing cataclasites is determined by multiple character of fluid-explosive phenomena exposed in tectonic zones upon alkaline metasomatism and ore deposition processes.
