What are the sedimentary basins in Nigeria?

Nigeria is underlain by seven major sedimenta- ry basins, viz: (from the oldest), the Calabar Flank, the Benue Trough, the Chad Basin, SE lullem- menden (Sokoto) Basin, the Dahomey Basin, and the Niger Delta Basin. Sedimentary succes- sions in these basins are of middle Mesozoic to Recent age.
