Within the West African Craton, there is a large amount of mining activity covering resources such as gold, copper, cobalt, silver, tin, and zinc. [ 24 ] Artisanal mining activity in the craton dates back to the early 1960s which used quartz vein debris as a gold indicator. [ 25 ]
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.
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.

On 27 August 2012, the West African Gas Pipeline was damaged when pirates who had tried to board an oil tanker in an attempt to get away from the pursuing Togolese Navy, severely damaged the pipeline with their anchor. For nearly a year, the supply of gas to Ghana, Togo and Benin ceased, causing major power supply problems to the affected ...
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.
ORION OIL LTD has gross revenues of over $1.1 billion, [1] and a member of the Infrastructure Partnerships for African Development (iPAD) [2] whose principal activities include the physical trading of crude oil and refined products including diesel, premium gasoline, jet fuel, fuel oil and other petroleum products worldwide and especially all along the African coast, from Senegal to South Africa.
Many cones are breached, and the dominantly basaltic and basanitic volcanic products are rich in peridotite and pyroxenite xenoliths and megacrysts. The youngest volcanoes rest on Neolithic terraces and are of Holocene age. The Tuareg Shield is a geological formation lying between the West African craton and the Saharan Metacraton in West Africa.
