The Jo urnal of African Earth Sciences is in the process of publicizing a Virtua l Special Issue (VSI) titled\, "The Geological Legacy of Africa." Over 25 topics have been identified in the research conducted. This presentation will address five of the topics in chronological order.\n\n\nThe oldest geological legacy of Africa is represented by the first geological map ev er discovered on Earth. The Africa-born concept of "metacratonization\;" the synthesis of geological data in early 2000\, has shown that cratons c an witness destruction through different mechanisms. The talk will move t o "Igneous Ring Complexes." Africa has more igneous ring complexes than a ny other continent on Earth. They are extrusive-hypabyssal igneous comple xes that span the Paleproterozic until the Oligocene. Four lithospheric-s cale geological mechanisms have been proposed to explain the formation of these igneous rocks\, and Africa has contributed two of these mechanisms .\n\n\n"Snowball Earth" is next where it has been proposed that the Earth was completely covered with ice during the Cryogenian and Ediacaran peri ods. Results from geological research in Namibia\, Africa have been used to advance the notion of "Snowball Earth."\n\n\nMoving on and "Transition ing from continental rifting to seafloor spreading" will focus on the Afa r Depression in eastern Africa. Afar is the only place on Earth where a r ift-rift-rift triple junction is exposed on Earth's surface. In 2005\, a magmatic-seismic event in northern Afar resulted in the opening of km-sca le long fissures within a matter of minutes. Afar research implies that " oceanization" occurs earlier than seafloor spreading\, hence a new unders tanding. Human evolution and geological and anthropological research in A far have informed our understanding of how the interplay between tectonic s and climate change has resulted in the evolution of early humans from H oninids to Hominis.\n\n\nDr. Abdelsalam's research is presented in 107 pu blications\, through financial support from the Petroleum Industry\, NSF and NASA. He has taught over 80 classes while at UT Dallas\, MO S&T and O SU\, Stillwater.
