West and Central African Rift System
The West and Central African Rift System is a rift system composed of two coeval Cretaceous rift sub-systems, the West African Rift sub-system and the Central African Rift sub-system. These are genetically related, but are physically separated and show structural differences. The Logone Birni Basin constitutes a transitional area between the two sub-systems.
The WCARS is older than the East African Rift System.
