    Abstract

    The present drainage of East Antarctica, with ice radiating from a central dome draped over the thick crust of the Gamburtsev Subglacial Mountains, recapitulates the Early Permian scene, including the south polar paleolatiude. The ancestral Gamburtsev Subglacial Mountains and a central Australian upland may have formed because of long-distance stress from the Variscan collision acting on zones of weak crust attenuated during prolonged subsidence of intracratonic basins. The mid-Carboniferous inception of widespread glaciation was possibly linked with vast uplands in northern and southern Pangea through the effects of Variscan topography and the removal of atmospheric CO2 during accelerated erosion and weathering. -from Author
