Geologic map of the Niger Delta Basin and the Benue trough, and the oil fields in the region. The Niger Delta Basin , also referred to as the Niger Delta province , is an extensional rift basin located in the Niger Delta and the Gulf of Guinea on the passive continental margin near the western coast of Nigeria [ 1 ] with suspected or proven ...
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. [ 1 ] [ 2 ] It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state ( Ondo ) from South West geopolitical zone and two states ( Abia and Imo ...
The Niger Delta Basin is an extensional rift basin where rifting occurred from the Late Jurassic to the Late Cretaceous.Cretaceous fracture zones, expressed as trenches and ridges, control the tectonic framework of the delta and separate the margin into individual sub-basins, which form the boundary faults of the Cretaceous Benue-Abakaliki trough.
Sketch map of Benue Trough. The trough has its southern limit at the northern boundary of the Niger Delta, where it dips down and is overlaid with Tertiary and more recent sediments. It extends in a northeasterly direction to the Chad Basin, and is about 150 km wide. The trough is arbitrarily divided into lower, middle and upper regions, and ...
Notable geographical features in Nigeria include the Adamawa Plateau, Mambilla Plateau, Jos Plateau, Obudu Plateau, the Niger River, Benue River, and Niger Delta. Nigeria is in the tropics, where the climate is very humid and seasonally wet. Nigeria has majorly four climate types; these climate types are generally gradated from south to north ...
It comprises six states – Akwa Ibom, Bayelsa, Cross River, Delta, Edo, and Rivers. The zone stretches along the Atlantic seaboard from the Bight of Benin coast in the west to the Bight of Bonny coast in the east. It encloses much of the Niger Delta, which is instrumental in
The states of Anambra, Benue, Plateau and Taraba have small-scale lead and zinc mining, from deposits that also have large quantities of cadmium, arsenic and antimony. Barite veins commonly contain lead and zinc in Plateau State and other parts of eastern Nigeria.
The oldest rocks in Niger, along the border with Burkina Faso and northern Ghana predate the 2.2 billion year old Proterozoic Birimian rocks common in much of West Africa. . The pre-Birimian crystalline basement rocks include gneiss and migmatite metamorphosed to amphibolite grade in the sequence of metamorphic fac
