The terrigenous rocks of passive continental edges are very important holding medium for the mesothermal and epithermal deposits of Kolyma-Chukotka region. The time-conjugated relation of epithermal and mesothermal ore forming is characteristic for volcanogenous zones and derives from the fact of successive evolution of epithermal (volcanogenous) and plutonogenous mineralization in the limits of united hydrothermal systems. The tardy and ending high-temperature stage mineral associations in the vein ores of the epithermal deposits are the most important indications of this relation.
