The position of palaeomagnetic zones together with the occurrence of some miospore species in the section of Salt Range enables its correlation with the reference sections of Tatarian on the Russian Platform. So the Wargal Limestone corresponds roughly to the Vishkilsky Horizon (newly proposed name instead of Sevedrodvinsky Horizon) both boundaries of the former being slightly younger than the corresponding boundaries of the latter. The analogs of the lower part of Vishkilsky Horizon and of the whole early Tatarian are seemingly absent in the Salt Range. The Amb Formation is most probably of Kazanian age.
