GEOLOGY AND STRATIGRAPHY OF SOUTHEASTERN NIGERIA.

The Lower Benue Trough lies between southeastern Nigeria (see Fig. 1) and often delineated into three prominent structural members namely, the Abakaliki Anticlinorium in the centre, Afikpo Syncline, and the Anambra Basin to the west. The southern sedimentary basin was formed after the break-up of the South American and African plate boundaries during the Cretaceous period.

Cretaceous sedimentary infill of these rift basins are made up of three identifiable uncomformity bounded depositional successions Albian-Cenomanian, Turonian-Coniacian, and Campanian-Maastrichtian (Obi, 2000). Within the core of the Abakaliki Basin, these sequences include the Asu River Group, Eze-Aku Shale and Awgu Shale. The Post-Santonian sediments overlying Nkporo, Ajali Sandstone Mamu, Nsukka Formation, Imo Shale and Ameki Formations occur within the adjacent Afikpo Syncline and Anambra Basin.

The stratigraphic successions of the lower benue tough consist of three stages which is marked by a drift in the axis of the sedimentary basins. These stages were the Abakaliki-Benue (Aptian-Santonian), the Anambra-Benin (Campanian-Mid Eocene), and the Niger-Delta Phases (late Eocene-Pliocene) (Oboh-Ikuenobe et. al., 2005). The more than 3,000 metres of rocks which include rocks of the Asu River Group, Eze-Aku and Awgu Formation, were deposited in the Abakaliki-Benue Basin, the Benue Valley and the Calabar Flank during the first phase.

The Santonian bending and uplift of the Abakaliki region and shifting of the depocenters leading to the formation of the Anambra Basin and the Afikpo Syncline occurred in the second phase (Oboh-Ikuenobe et. al., 2005). The resulting successions comprise the Nkporo Group, Mamu Formatiom, Ajali Sandstone, Nsukka Formation, Imo Formation and Ameki Group.

The third sedimentary phase resulted in the creation of the Niger Delta Basin, which began in the Late Eocene as a result of orogeny that led to the deformation of the Abakaliki Basin tilting the depositional axis toward the south of the Anambra basin (Obi and Okogbue, 2004). The first sedimentary cycle began in the Albian-aptian and continued until the Santonian with minor break in sedimentation during the Cenomanian (see Table 1). The Aptian Ogoja Sandstone, the Albian asu River Group, the Amasiri Sandstone, the Cenomanian Odukpani Formation, the Turonian Eze-Aku Group and Coniacian Awgu Formation were deposited as first sedimentary cycle deposits (Hoque and Nwajide, 1988).
