- Abstract
This article discusses the results of Ar/Ar 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).
