Prospects of the Tymoshivsko-Znamianskyi potential rare-metal ore area of Inhulskyi 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 Tymoshivsko-Znamianskyi potential rare-metal ore area of Inhulskyi megablock of the Ukrainian Shield. The results of studies of regularities of raremetal mineralization’s placement in Tymoshivsko-Znamianskyi potential ore region of the Inhulskyi megablock of the Ukrainian Shield are presented. The structural control of the great part of the detected geochemical anomalies, geochemical halos, manifestations and ore manifestations by certain systems of rupture faults and their intersection nodes is determined. The typical local features of manifestations of rare metal mineralization in small uranium deposits and large ore manifestations of this region and uranium mineralization of different genetic types, in particular hydrothermal mineralization of vein-stockwork type in mineralized fault zones are presented. According to the degree of manifestation of the complex of criteria, prospective ore and potentially ore nodes are discovered for possible detection of industrial concentrations of rare metals and rare-earth elements within the Tymoshivsko- Znamianskyi potential ore region, as well as uranium ores of various genetic types, in particular superimposed rich hydrothermal mineralization of vein-stockwork type. There were developed recommendations for further research in the Tymoshivsko-Znamianskyi potential ore region with the aim of farther development of rare and rare-earth elements raw material base.
