Nigerian planation surfaces and crusts of weathering associated with them

Abstract

Three groups of planation surfaces were identified in Nigeria: the Gondwana and Post-Gondwana, the African and Post-African surfaces. The African and Post-African surfaces are of Cenozoic age and are associated with lateritic crusts of weathering, the latter being mostly of Pliocene-Pleistocene age. They are now undergoing erosion, rearrangement and removal.
