Abstract
The 40Ar–39Ar dating of mica from schists and blastomylonites, sampled within the limits of a fault that separates the Eastern zone of the Middle Urals, sinking beneath the sedimentary cover of the West Siberian Plate, from the structures located to the west of this plate, in the exposed part of the Urals, has shown that the final phase of deformations was represented by sinistral strike-slip faults trending submeridionally with an age of 251 Ma. The deformations studied virtually exactly coincide in time with the formation of submeridionally oriented grabens in the basement of the West Siberian Plate.
