New Data on the Platinum Potential of Plutonogenic Gold Deposits in the Upper Amur Region

摘要

In the Russian Federation, economic-grade concentrations of platinum group elements (PGE) have been detected in many gold deposits, such as Natalka ,Zun-Kholba, Irokinda , and Sukhoi Log. However, the platinum potential of gold deposits in the upper Amur region has been investigated insufficiently so far. Although economic-grade PGE concentrations have not been discovered here, the abundance of signs of Pt concentration suggests that gold deposits of this region can also incorporate PGE mineralization.
