| Abstract: | A structural interpretation of the first Re–Os dating of pyrite and arsenopyrite from the Malinovsky gold deposit is given. Comparison of the obtained data and the known ages of ore-bearing granitoids from the ore field made it possible to determine the age of mineralization as 100–90 Ma. This age corresponds to the time of completion of the Albian–Cenomanian geodynamic setting of the transform margin of the Asian Continent with significant left-shear dislocations, as is evident from the structural patterns of localization of ore bodies and magmatic rocks. The time interval and geodynamic conditions for the formation of the Malinovka deposit are similar to those of many gold and gold-bearing deposits within the Sikhote-Alin orogenic belt and the south of the Korean Peninsula.
