The conditions of the occurrence, structure, material composition and controlling factors of Krasnokutsky rare-metal-titanium placer deposit localized in the Miocene sediments of the North-Eastern slope of the Dnieper-Donets basin are investigated. Distinguished lithofacies complexes (alluvial-deltaic, coastal and shallow marine, aeolian) correspond to the Lower (Aquitanian), Middle (Burdigalian) and Upper (Langhian) members of Novopetrovskaya Formation of Miocene. Placer bodies are localized in the littoral marine-coastal complexes of Middle Novopetrovskaya sub-formation. Placerforming process is related to phases of stabilization of the shoreline of the regressive phase of the Sub-Paratetic basin. Main search and forecasting criteria for the identification of promising sites within the Kharkiv-Sumy placer-bearing zone are stabilization of the shoreline in the Middle Novopetrovskaya time simultaneously with development of transverse thereto alluvial-deltaic structures that supply weak mineralized sediments. Also, the deltaic ledge breaking the monotony coastal migration and playing the role of structural-sedimentary traps. The developed digital structural-lithological model of the Krasnokutskoye mineral deposit allows us to offer a set of criteria for comparative evaluation of different placer-bearing areas in order to determine the order of their development. The mineral composition of productive deposits is typical for the placers of the region and for rare-metal-titanium placers as a whole; the increased content of rutile and zircon, which rise the industrial value of placers of this zone, are associated with the influence of crystalline rocks of the Voronezh massif.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
