Abstract
A new model of the junction of the Ural fold belt with the Russian and West Siberian Platforms along the Europrobe Seismic Reflection profiling in the Urals (ESRU) down to a depth of 15 km is constructed. 2Dmodeling of the density and magnetic properties was performed using seven profiles and was accompanied by an estimate of applicability of the method. In the west, the upper part of the model is represented by terrigeneous- carbonate deposits, and the bottom part shows the structures of the basement of the Russian platform, which becomes thinner eastward and plunges beneath the Ural structures. The most significant difference in the West Siberian part of the transect is the great “length” of the entire structure of the Earth’s crust. This is caused by the Early Triassic extension accompanied by the formation of a system of Triassic graben-rifts.
