摘 要:When gigantic meteorite impact sites in Southern Africa are plotted on the geological map of the region, they overlap with the SW-NE fault lines and it indicates that meteorite impacts have contributed to the geological structure of the region. The Morokweng Meteorite Impact of 145 Ma (Million years ago), at the J/K (Jurassic/Cretaceous) boundary, seems to have broken up the Gondwanaland. It is plausible that, at the time of continental break-up, seawater poured into Morokweng crater and ignited a gigantic volcanic eruption which delivered low viscose magma into the outer space to form the Moon. An extremely flat surface of the Megakalahari extending 3,800,000 sq. km at 800-1,200 m above sea level in the central and southern Africa seems to be the terrestrial residue of fluid magma at the end of the volcanic event.
