GEOLOGICAL STRUCTURE OF THE USTUK ORE DEPOSIT, ORE FORMATION OF URANIUM AND RARE METALS

The article provides information about the mineralization of the Ustuk deposit with uranium and other rare metals. The
distribution of radioactive elements in rocks has been studied in field studies. As a result of the research, it was found that
uranium-rich vanadium mineralization and secondary minerals of carnotite-tyuyamunite series were formed. Also, the primary
minerals of uranium and rare earth elements were carried out on the metamorphogenic quartzing front, enriching Mountaineers
with uranium and rare earth elements. A favorable environment for quartzing to scarnoids (geochemical barrier) was created and
ore deposition was carried out. In primary ores, carriers of uranium and rare earth elements 91.25% consisting of cerium,
lanthanum, prazeodymium and neodymium oxides were identified as follows: ittrotitanite, apatite, rutile, leukoxene, ortite,
uraninite, monasite, xenotim. The areas of occurrence of quartz ores with sulfides and iron hydroxides are highlighted.
