Modern paleomagnetic data allow for developing reliable APWP for Siberian and European platform. Comparison of the Siberian and European APWPs shows that since the Mesozoic time both platforms were part of the North Eurasian tectonic plate (North part of Pangea supercontinent). For the Permian period (since early Permian time to P-T boundary), the relative position of the Siberian and European platforms can be described by the rotation of the Siberian block relative to the European block clockwise by 46° around the Euler pole, located in the area of the Northern Land (Severnaya Zemlya archipelago). Such a mechanism of interaction between Siberian and European platforms has determined the structural figure of deformations within the folded systems of the Arctic and Central Asian fold belt that have survived to the present day. Probably, the problem of space in the subconsolidated crust of Western Siberia, caused by the convergence of Siberian and European platforms, was realized through the constriction of the structures of the mobile belt to the north and south along the systems of shear zones.
