Geologicheskii Vestnik

The article proposes an updated scheme of age division and correlation of granitoids of the Lyapinsky anticlinorium, which occupies the axial part of the Central Ural uplift in the Subpolar and Northern Urals. The scheme is developed on the basis of a comprehensive analysis of the geological position of granitoid massifs, petrogeochemical, mineralogical features and metamorphism of rocks. It is shown that granite formation processes in the subpolar-northern Ural segment of the earth's crust manifested themselves over a long period of time, starting at least from the end of the early Proterozoic and up to the early Paleozoic, but developed discretely with a large break, falling on a significant part of the Riphean period. Possible geodynamic settings for the formation of granitoid complexes of different ages are considered.
