Abstract
A 450 km long composite crustal section of the Urals folded system at 67º N and 60–90° E has been compiled from seismic data on the Polar Urals transect and the results of targeted studies. The main elements of the subsurface structure at more southerly latitudes are preserved for this cross section. The general deep–seated structure is divided into the western and eastern branches. The western one has a northwestern trend and corresponds to the West Urals megazone. The eastern one, with a northeastern trend, includes the Central Urals and East Urals megazones.
