Uranium mineralization of Vitim paleovalleys deposits
The results of material composition study of ores of seven paleovalley deposits of Khiagdinsky ore field (Vitim uranium ore district) are summarized. High dispersion of ore substance, that is characteristic for ores, led to the choice of EM as the main method of mineralogical research. The predominant ore component is Ca-phosphate of the tetravalent uranium, ningyoite, which is represented by crystalline and mineraloid forms. The ores are a little-known earlier and are new type of industrial uranium ore for Russia - phosphate black’s.
