A Geodynamic Model of the Evolution of the Earth’s Crust of the Alpha Ridge–Mendeleev Rise and the Podvodnikov Basin in the Mid-Cretaceous

We propose a geodynamic model capable of explaining the formation of structural features of the Earth’s crust in the Amerasian Basin. The model relates the evolution of the crust of the Alpha-Mendeleev Rise and the Podvodnikov Basin in the Cretaceous to the dynamics of an isometric convective cell in the upper mantle, which can be interpreted as an upper mantle plume. The presented results of numerical modeling confirm the applicability of the presented approach for explaining the geodynamic evolution of the continental crust of the Alpha-Mendeleev Rise and the surrounding basins of the Amerasian Basin in the Cretaceous.
