ANCIENT DIAMOND PLACERS OF THE RUSSIAN FEDERATION

The article overviews ancient diamond placer deposits in Russia, established in coastal marine and continental sediments of different ages. The authors specify the structure, composition, diamond potential of commercial placers and the stages of their formation. The balance reserves of ancient diamond placers are to be located in the territory of the Republic of Sakha (Yakutia) and on a small scale in Perm Region. The Jurassic placers of short transfer from the Nakyn field kimberlite pipes are uniquely productive; the Carnian and Rhaetian sediments of the Upper Triassic on the northeastern Siberian platform have the greatest predictive potential.
