For the first time, the North Yenisei orogen was isolated in the Precambrian folded frame in the west of the Siberian craton. On the basis of a set of methods, polycyclicity and evolution of tectonic-metamorphic and magmatic complexes, the stages of its formation have been established at the boundaries (billion years): (1) Grenville (1.18-0.85), (2) Early Baikal (0.85-0.80), (3) the stage of destruction of Grenvillids (in the west, 1.18-0.80), culminating in the accretion-collision stage (0.80-0.60), and (4) late Baikal orogeny (in the east, 0.80-0.60). The correlation of the geological development of the North Yenisei orogen with the tyranids of the Urals is assumed.
