Аннотация
The date of cessation of calc-alkaline volcanic complex accumulation within the Devonian (Frasnian) island arc in the Northern Urals was determined for the first time. It was demonstrated that the geochemical characteristics of the Late Devonian volcanic rocks of the Limka Formation are similar to those of the rocks of mature island arcs and active continental margins. A certain delay in the final episode of the calc-alkaline volcanism in the Northern Urals as compared to a similar event in the Southern Urals is probably due to oblique subduction.
