Peculiarities of gold deposits of northern Urals and Yan-Kolyma belt

The peculiarities of gold deposits of northern wing of Ural (southern part of Polar and Subpolar Urals) and Yan-Kolyma orogenic belts have been compared. It is shown that despite certain similarities of mineral associations of gold-quartz deposits from these belts, there are considerable distinctions observed in the development of palladium-platinum profile of gold ores in the Northern Urals, resulted from general femic-salic metallogenic specialization and mediate mantle genesis of platinoides in these ores. The latest findings of platinoid phases in a number of gold deposits of Yan-Kolyma belt of both «black shales» type, and granitoid-related, put a question about mantle influence to the process of formation of orogenic gold deposits and in typically crustal Yan-Kolyma metallogenic province.
