Abstract
Analysis of accumulated information and new geological and geophysical data permitted us to improve the model for the structure of the Yenisei Range and its multistep thrust over adjacent regional structures. Quantitative parameters of the dislocation of the Riphean-Cambrian horizons, interpretation of seismotomographic sections, and comparison of their geoelectric characteristics to depths of 10-15 km show a principal difference between the areas of the West Siberian Plate and Siberian Platform adjacent to the Yenisei Range, though the plate has much in common with the range.
