Abstract
The basic features of mineralogy and geochemistry of the gold-ilmenite placers, which are spatially and genetically associated with the Ariadnoye intrusion of ultrabasites (the right bank of the Ussuri River), are provided. The composition of platinum and gold was studied, and a complex of associated high-tech metals was revealed. It has been established that ultrabasites acted as the main supplier of useful components into the placers. Insightful mineralogical and geochemical studies of ore-bearing intrusions of ultrabasites of the Sikhote-Alin orogenic belt will expand the prospects for the raw material base of strategic metals in the southern part of the Far East.
