Nigeria's almost 1000000 km surface area is equally divided between crystalline basement rocks and Cretaceous to Quaternary sediments and volcanics. The basement rocks lie within the Pan African Mobile Belt between the West African and Congo Cratons (Ajibade et al., in press). Much of the basement is reworked older crust, some of which may be Liberian (± 2,500 Ma), which has been reworked by at least two major orogenies, the Eburnean (2,000 ± 200 Ma) and the Pan African (900-450 Ma) with the addition of major granitoid masses (the Older Granites) and some supracrustal materials which occur in N-S linear schist belts in the Western Province. Mesozoic alkaline ring complexes are confined to a narrow central belt and Cretaceous sediments are preserved in major basins (Dahomey, Benue, Bida, Chad, Sokoto and Niger Delta) which are structurally controlled and were initiated at the break-up of Gondwana. The mineral production of Nigeria is not remarkable except for Sn and Nb though both are now relatively unimportant on a world scale. Many other small mineral deposits and occurrences of several types are recorded. Petroleum is of major economic importance and its location in the Niger Delta, off-shore and possibly in other sedimentary basins now being explored, is structurally controlled but it will not be further discussed.
