Abstract
In the context of models of mantle circulation beneath the continent, coupled with the subduction of the oceanic lithosphere, a direct link between the kinematics of plate tectonics in the Northwest Pacific Ocean and geodynamic evolution of the Arctic and northeastern Asia in the upper Cretaceous and Cenozoic is revealed. A simple geodynamic explanation is given for the emergence and subsequent termination of Cenozoic shear deformations in the Khatanga–Lomonosov fault zone, which is an important argument favoring the idea of the Lomonosov Ridge as a natural extension of the Eurasian margin to the Arctic (Amerazian) basin.
