| Abstract: | The article describes the Vetvistoe ore occurrence located in the Okhotsk segment of the Okhotsk–Chukotka volcanic belt. The ore field is confined to the exomorphic contactof a large Late Cretaceous granitoid intrusion and is formed by Jurassic sedimentary rocks in which garnet–pyroxene skarns with Pb–Zn mineralization are developed after intercalations of calcareous sandstones. The skarns are overlain by sericite–quartz beresites with disseminated Au–Ag–Bi–Te mineralization. Mineralization formed from initially high-temperature (600°C) and highly concentrated (29–20 wt % NaCl equiv.) gas-saturated hydrothermal solutions–brines with a predominantly CaCl and LiCl composition at their boiling, periodic dilution (up to 1 wt % equiv. NaCl), and a change in sulfur, oxygen, and tellurium fugacities and pH values. The Vetvistoe occurrence differs from "classic" Pb–Zn skarn deposits in the lesser development of carbonate rocks in the ore-bearing sequence and the overprinting of late Au–Ag–Bi–Te mineral parageneses.
