Abstract

An attempt to provide a new explanation for the change in the geodynamic regime in the Early Cretaceous is presented below. It accounts for data on a number of global geodynamic characteristics in the range of 200–65 Ma reflecting processes both deep in the Earth and on the surface, and seemingly directly unrelated to the formation of a transform margin in Eastern Asia. It has been found that the geodynamic regime changed in the range of 115‒110 Ma.
