Similarity and difference in structure of the Ural and Paikhoy-Novaya-Zemlia fold belts

Characteristic features of deep structure and composition of Ural (UFB) and Paikhoy-Novaya-Zemlia (PNZFB) fold belts, which were investigated with the use of results of geological and geophysical investigations along reference geophysical profiles (geotransects) are considered. In the structure of Uralian deep sections typical elements of collisional orogen are distinguished: deformed margin of submerged plate, suture zone and deformed margin of override plate. Participation in the process of the Late Paleozoic collision more than «Baltic» и «Kazakhstan» plates, but micro plates of continental type lead to complication of typical model of collision orogen due to inclusion into the UFB deep structure additional blocks and suture zones. PNZFB zonality is not typical for classical collision orogens. Fold-thrust belt on the «Svalbard» plate margin is modeled in its deep section. Intensity of the fold-thrust deformations decreases to relict oceanic basin, which is modeled in the basement of the South-Kara sedimentary depression.

Riftogenic structures in the west sector of amerasia basin based on complex geophysical data

The time seismic reflection sections obtained in Podvodnikov basin (Central Arctic)  during expedition «Shelf-2011» were interpreted. The tectonic zoning of Podvodnikov basin and adjacent structures was carried out with the use of lineamental analysis of bathymetric, anomalous gravitational and magnetic maps. The  distribution of riftogenic  structures is shown  within the whole Podvodnikov basin. The thickness of riftogenic complexes reaches 5 km.

Structural and petrophysical characteristics оf intraplate geodynamic settings of the Barents-Kara region and Northern margin of Eurasian continent

Characteristic features of deep structure and petrophysical parameters  of intraplate structures (hot spots, intracontinental rifts, inrtraplate basins and passive continental margins) are considered. Examples of the structures of Barents-Kara region and Eurasian continent north margin are presented.
