| Abstract: | By interpretation of the complex geological and geophysical data and paleotectonic reconstructions based on the results of deep seismic tomography, a new deep geodynamic mechanism is developed to describe the formation and evolution of Amerasian and Eurasian basins, together with their adjacent geological structures of the Arctic region. The Mesozoic and Cenozoic transformations of the lithosphere in a number of regions of the Arctic Ocean are considered. The role and place of the upper-mantle convection is explored, and the chronology of the key structure-forming events is analyzed. |
