Earth’s crust structure of the Mendeleev Rise and its connection with Eurasian continent (by geophysical data)

The Earth’s crust and the upper mantle structure in junction zone between the Mendeleev Rise and Northern Eurasia shallow water shelf have been identified by the interpretation of current deep seismic and gravity anomalies. The Chukchi Fold Belt, the Wrangel­Herald Ridge, the North Chukchi Trough, the Mendeleev Rise, the Chukchi Basin and the Chukchi Plateau velocity and density models are described in the paper. Structural relations between these taxa and their geological structure are discussed according to coordinated 3D system of velocity and density models.
Keywords: DSS and CDP seismics, velocity and density models, the Mendeleev Rise, the North Chukchi Trough, continental crust.
