Patterns of ore localization and the mineral composition of ores and ore-bearing rocks of the Koretkonde uranium deposit (Vitim ore-bearing region)

This work presents the geological structure of the Neogen uranium-bearing ore sedimentary strata that filled the paleovalleys of the Koretkonde deposit. As a result of work we carried out, productive deposits were stratigraphically divided, the patterns of the localization of uranium mineralization were studied, and lithological and mineralogical ore-controlling factors were revealed. The main mineral phases of uranium were identified with scanning-electron microscopy and microprobe studies. In the future, a more detailed study of the deposits is planned in order to reveal methods for improving the efficiency of their exploration and organize the search for uranium deposits of such a type within the Vitim uranium-bearing ore region to expand the mineral resource base of Russia.
