Mineralogical Indicators of Diamond Potential of the Urals Placers

Abstract

The problem of placer diamond potential on the territory of the western slope of the Urals is considered. The mineral composition of the heavy fraction of the Takata intermediate diamond collector in the Vishera diamondiferous region, which feeds the diamondiferous deposits of the spatially associated Cenozoic depressions, has been studied. Based on known deposits, a brief history of mineralogical studies in the Vishera and Chikman diamond-bearing regions is given. The geological structure, material composition of the detrital material, diamond content, and the proposed sources rocks for the discovered in 2022 currently largest Syuzevskaya placer in the Urals in the Chikman diamondiferous region, are described. Criteria for searching of similar placers in the diamond-bearing regions of the Urals and in the regions with a similar geological structure are proposed. The prospects and problems of the mineralogical method in the Urals region are outlined.
