South of the mountains, the West African Craton is relatively flat, mostly desert or dry savanna apart from the areas near the Atlantic or Gulf of Guinea. However, below the surface there are ancient sedimentary basins such as the Taoudeni basin that may contain large reserves of oil and gas. [21]
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]

Volgo-Uralian Craton, Russia (3.0–2.7 Ga) Baltic Shield, part of the East European Craton; Fennoscandian Shield, the exposed Northwestern part of the Baltic Shield in Norway, Sweden and Finland (3.1 Ga) Karelian Craton, part of the Fennoscandian Shield in Southeast Finland and Karelia Russia, (3.4 Ga)
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.
Geologic map of Ivory Coast, in which the "Eburnean, geosynclinal facies" is equivalent to the Birimian. [1]The geology of Ivory Coast is almost entirely extremely ancient metamorphic and igneous crystalline basement rock between 2.1 and more than 3.5 billion years old, comprising part of the stable continental crust of the West African Craton.

The Zimbabwe Craton is an area in Southern Africa of ancient continental crust, being a part of the ancient continent of Western Gondwana, with rocks dating back to the early Archean Eon, possibly as early as 3.46 billion years ago . [1] The craton is named after the country of Zimbabwe where the majority of the
The Ogaden Basin is an area of Huwan that may hold significant reserves of crude oil and natural gas. [1] The basin covers an area of some 350,000 square kilometres (135,000 square miles) and is formed from sedimentary rocks up to 10,000 meters (6 miles) thick. [2] It has geological similarities to other hydrocarbon-rich basins in the Middle ...

The geology of Zimbabwe in southern Africa is centered on the Zimbabwe Craton, a core of Archean basement composed in the main of granitoids, schist and gneisses.
