Paleo-geomorphological environment of diamond placers formation at south-western slope of the Tungusian syneclise during the Late Paleozoic

Abstract

Paleo-topography of the east slope of the Tungusian syneclise having been reconstructed permits to trace placers-forming processes. Most favourable conditions for diamond placers formation existed at uplands' slopes dated from Middle Carboniferous, as well as at islands, Placers remote from the source areas could be formed in the zones of contact between uplands and lowlands and also in the coastal zones of seas and large lakes. These pale-landforms are recommended for search of diamond placers.
