The basement rock of most of Africa was formed in the Precambrian (approximately 4.5 billion years ago) and is much older than the Atlas mountains lying in Africa. The Atlas formed during three subsequent phases of Earth's history.

The first tectonic deformation phase involves only the Anti-Atlas, which was formed in the Paleozoic Era (~300 million years ago) as the result of continental collisions. North America, Europe and Africa were connected millions of years ago.
