摘要：
This article discusses the results of 40Ar/39Ar geochronological studies on the age of the gold-silver mineralization of the Dess occurrence hosted by the granitoids of the Tynda-Bakaran rock complex, which is 129–128 Ma. This estimate coincides with the time of the formation of the Mo mineralization (125–122 Ma) hosted by the rocks of the same rock complex. This allows dating the Au-Ag and Mo mineralizations from the same ore formation period that manifests itself in the granitoids of the North Stanovoi metallogenic belt that were formed in the environment of a transform continental margin. There exists the following sequence of changes in the mineral occurrences from the south to the north: Au-Ag-Au-Mo(Au).
