Paleoenvironments of the Gulf of Guinea [PDF]

, 1981
Foraminiferal assemblages in three marginal basins in the Gulf of Guinea (namely, the Benue Trough, the Dahomey Embayment, the Niger Delta) show maximum development during the major marine transgressions. The Oligocene and younger transgressions are more pronounced in the Niger Delta where fossiliferous marine shales are intercalated within deltaic ...
