The geology of Africa is varied and complex, and gives rise to the wide variety of landscapes found across the continent. The African continent rests over two main plates. The African Plate , accounting for the whole of north Africa, and the Somali Plate , which accounts for the eastern side of mid and southern Africa. [ 1 ]
Features Africa , Atlantic Ocean , Mediterranean Sea , Red Sea The African plate , also known as the Nubian plate , is a major tectonic plate that includes most of the continent of Africa (except for its easternmost part ) and the adjacent oceanic crust to the west and south.

About 180 million years ago, a mantle plume under southern Gondwana caused bulging of the continental crust in the area that would later become southern Africa. [2] Within 10–20 million years, rift valleys formed on either side of the central bulge and flooded to become the proto-Atlantic Ocean and proto-Indian Ocean more or less along the present southern African coastline and separating ...

The Ecca Group is the second of the main subdivisions of the Karoo Supergroup of geological strata in southern Africa.It mainly follows conformably after the Dwyka Group in some sections, but in some localities overlying unconformably over much older basement rocks.
