Noble metal ore formations in the activation zones in the eastern Yana-Kolyma Fold System (Magadan Region, Russia)

The article deals with ore formations in the eastern part of the Yana-Kolyma Fold Region, which host gold and silver as the main components. For gold and silver-bearing formations of volcanogenic and plutogenic genesis, structural and tectonic conditions typical of their formation, characteristic producing magmatic and metasomatic ore-bearing formations, mineral types of ores, and metallogenic trend are determined. Examples include the most typical ore clusters (including potential ones), ore fields, deposits, and ore occurrences.
Keywords: ore and ore-bearing formations, mineral type, metallogenic zone, gold, silver.
