The Niger Delta has three major depositional prisms: (1) a Cretaceous deltaic complex developed 600 miles inland from the present mouth of the Niger Delta, (2) a Late Cretaceous to Palaeogene "proto Niger" delta complex which was formed seaward of the earlier delta, and (3) the younger Cenozoic Niger Delta complex which was built out over newly formed oceanic crust as the South Atlantic opened during the separation of the South American and African tectonic plates.
Most of the valleys in the Baltic Sea area were probably formed in the Late Palaeogene and Neogene when the Earth's crust was much higher than at present due to the riftogenesis in the North Atlantic region (Puura 1980).
