Prospects for discovery of industrial concentrations of rare and rare-earth elements in the Alekseevsko-Lysogorskiy uranium-ore area of Ingulskiy megablock of the Ukrainian shield
Abstract
The article presents the results of the assessment of the prospects for discovery of industrial concentrations of rare and rare-earth elements in the Alekseevsko-Lysogorskiy uranium-ore area of Ingulskiy megablock of the Ukrainian Shield. General pattern in the distribution of industrial objects of rare-metal and uranium mineralization in the Ingulskiy megablock of the Ukrainian Shield, caused by similar deep-seated factors of ore formation, are revealed. The complex of regional and criteria of uranium mineralization of a rare-earth-thorium-uranium formation in silicon-potassium metasomatites of the Alekseevsko-Lysogorskiy ore region is substantiated: geological-structural, mineralogical-geochemical, hydrogeological. There were presented characteristic local features of manifestations of rare-metal mineralization in this region. Based on the results of the analysis of geological and geophysical materials, it was possible to identify new uranium and complex uranium rare-metal deposits with higher mineralization parameters in optimal geological and structural conditions in the Alekseevsko-Lysogorskiy uranium ore region. There has been established the possibility of identifying within the limits of known uranium ore fields, manifestations of uranium mineralization of the rank such as deposit, ore occurrence of this uranium ore region of industrial concentrations of rare and rare-earth elements. The possibility of increasing the value of known deposits and ore occurrences of uranium of the Alekseevsko-Lysogorskiy uranium ore region due to the complexity of ore use is substantiated. According to the degree of manifestation of the complex of criteria, prospective ore and potentially ore zones are discovered for possible detection of industrial concentrations of rare metals and rare-earth elements within the Alekseevsko-Lysogorskiy ore region. There were developed recommendations for further research in the Alekseevsko-Lysogorskiy uranium ore region with the aim of improving the quality of the raw material base of rare and rare-earth elements.
