Abstract

The hypothesis of Podvodnikov basin's riftogenic origin is based on idea of continental type of crust in this region, which has become very popular in recent years. A seismic survey had been carried out in this region during "Shelf-2011" expedition. The qualitative interpretation of several common-midpoint stacks was done by author. Some features of riftogenic structures are quite visible on seismic sections presented. For velocity analysis a number of reflection-refraction soundings with sonobuoys had been carried out too in above-mentioned expedition. The velocity modeling through primal algorithm based on these sounding's data was performed by author. It shows regular p-wave velocity increase in sediments with depth increase. The velocity for acoustic basement upper boundary turned out to be 5.8 km/s, which is typical for consolidated crust.
