Paleomagnetic studies of the early Carboniferous strata of Tuva have been carried out. As a result of the component analysis, post-folding secondary and pre-folding, probably close to the primary components of magnetization, were identified in them. Coordinates of the paleomagnetic pole for the Lower Carboniferous of Tuva: Φ = 53.8∘N, Λ = 141.7∘ E, A95 = 9.6∘. The lower Carboniferous strata of Tuva were formed at high latitudes: 51–70.5∘N. The Tuva block as a whole did not experience significant rotations relative to Siberia in the Phanerozoic. Nevertheless, in the Late Devonian in the territory of Tuva, shear deformations and rotations of rocks in the horizontal plane took place.
