Abstract
The data are presented on the geological and isotopic age of gold deposits of the Solovyovsky gold ore center in the Amur province, assigned to the gold-polymetallic, gold-sulfide-quartz, and goldquartz formation types. It is demonstrated that the geological and isotopic age of the most productive ore deposits of the gold-polymetallic (Berezitovoe) and gold-sulfide-quartz (Kirovskoe) types is Early Cretaceous according to geological data and Barremian (in the range of 131–125 million years) according to isotopic determinations. The geological age of poorly productive ore deposits of the gold-quartz type is difficult to determine due to the fact that the host rocks are most often represented by gneisses and crystal shales of Precambrian age. The isotopic age of formation of the Snezhninka and Zolotaya gora gold-quartz deposits is, respectively, Late Triassic (212 million years) and Late Jurassic (155 million years).
