At that time, the Congo Craton lay to the west of the Amazonian Craton, and the West African Craton lay to the south where both were rotated about 180° and retain this relative configuration. [13] Around 750 million years ago Rodinia rifted apart into three continents: Proto-Laurasia, the Congo craton and Proto-Gondwana. [14]
Approximate extent of Taoudeni basin Major West African sedimentary basins. The Taoudeni Basin is a major Sedimentary basin in West Africa, named after the Taoudenni village in northern Mali. It covers large parts of the West African craton in Mauritania and Mali. It is of considerable interest due to its possible reserves of oil. [1]
Ghana and Mali are the second and third largest producers of gold in Africa, respectively. [ 1 ] The Birimian terranes in the southern part of the West African craton are a mix of metamorphosed volcanic , sedimentary , and plutonic rocks and low-grade metavolcanics and metasediments.

Paleoproterozoic rock units belonging to Birimian Supergroup, common across West Africa, dominate northwest and southwest Ghana. The Birimian Supergroup has two units, one a succession of sedimentary rocks including phyllite, tuff and greywacke overlain by conglomerate, sandstone and shale and the other a volcanic tholeiitic magma series.

The production of oil and gas is important to Algeria's economy, being Africa's main producer of the latter. Its reserves were estimated at 4.502 trillion m 3 at the end of 2008. Productive fields are found in anticlines, faulted anticlines or domes; the reservoirs being in Cambro-Ordovician, Triassic, Devonian, and Carboniferous sandstones.
