Tectonic Structure of the Junction Zone between Lomonosov Ridge and the Eurasian Continental Margin

The tectonic structure of the junction zone between Lomonosov Ridge and the Arctic Continental Margin of Eurasia was clarified due to comprehensive analysis of data on the potential fields and the results of the newest seismic surveys. The existence of the hypothetical Khatanga–Lomonosov transform zone is not confirmed by the established system of disjunctive dislocations. The results obtained confirmed and detailed the model, according to which the opening of the Eurasian Basin was accompanied by movement of the Lomonosov Ridge and adjacent from the east and south geological structures, as a parts of the North American Plate, away from the Barents–Kara margin.
