Structural map

The map shows the geological framework of West Africa reflecting the tectono-metamorphic, magmatic, and sedimentary history of the past c. 3.5 billion years. The basin-and-swell structure is formed by major crustal Precambrian domains – the West African craton, the Trans-Saharan Mobile Zone, and the fold and thrust belts of the Pan-African Orogeny – and large intracratonic sedimentary basins, intracontinental rift basins, and the Atlantic margin basins reflecting the Meso-Cenozoic history of West Africa Source: BGR, BGS, BRGM, EAWAG & UNESCO
