摘要：
The 40Ar/39Ar age of the productive stage of the ore-forming hydrothermal process at the large Tokur gold deposit is 122.4 +/- 2.0 Ma. This estimate suggests a paragenetic relationship of this deposit with the nearly exposed Karaurak subvolcanic trachyrhyodacite intrusion, the U-Pb zircon age of which was previously estimated at 120 +/- 5 Ma. The age of mineralization at the Tokur deposit is close to the time of formation of some other deposits in the Russian Far East localized in various structural units. DOI: 10.1134/S1075701511030081
