Reconstruction of the age of provenances of terrigenous material of the Upper Neogene Ergeninskaya suite, which contains rare metal-titanium placers within the Ergeninskaya Upland of the same name, was carried out using a combination of lithological and mineralogical methods, including geochronological U–Pb dating of detrital zircon. Generalization of the obtained data indicates that the source of terrigenous material was the crusts of chemical weathering developed along the Neoproterozoic end the Mezoproterozoic (Riphean) volcano-plutonic complexes of the Voronezh anteclise (VA) and the Ukrainian Shield (USh), almost completely eroded by now, Paleoproterozoic and Archean crystalline rocks of the basement of these tectonic structures. Most likely, the destruction products of the above-mentioned rocks participated in the structure of the main intermediate collector, the role of which should have been played by sedimentary formations of the Carboniferous age, which have an areal distribution in the south of the East European platform. The southeastern edge of the territory of the Donetsk folded structure acted as a proximal source of terrigenous material during the accumulation of the Ergeninsky placers, as indirectly evidenced by single dZr crystals with Triassic and Carboniferous U-Pb datings.
