Geological structure of Ustuk ore field features of mining
Abstract
The article provides information on mineralization of the Ustuk mineral field with uranium and other rare metals.The distribution of radioactive elements in rocks was 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 enriched with uranium and rare earth elements in the metamorphic quartzization front. A favorable environment (geochemical barrier) for quartzization of skarnoids was created and mineral deposition took place.Carriers of uranium and rare earth elements in primary minerals, consisting of 91.25% cerium, lanthanum, praseodymium and neodymium oxides, were identified as: yttrotitanite, apatite, rutile, leucoxen, orthite, uraninite, monazite, xenotime. Quartz ore deposits with iron sulfides and hydroxides have been exposed in the area.
