Explosive volcanism and the geological history of the Antarctic Atlantic

We made a summary of the materials from DSDP and ODP initial reports on deep-sea drilling and other data on areal and stratigraphic distributions and compositions of pyroclastic material in the sediments of the Antarctic Atlantic. These data were used to study the geological history of the region, which was formed approximately 165 Ma ago as Gondwana broke up as part of the Southern Ocean, being accompanied by explosive volcanism of various types (volcano-fissure volcanism, riftogenic, plume-induced, that of “hot spots,” and the island arc type).
