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 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.
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 ...
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 ...
The riverine area of the Niger Delta is a coastal belt of swamps bordering the Atlantic. The mangrove swamps are vegetated tidal flats formed by a reticulate pattern of interconnected meandering creeks and tributaries of the Niger River. About 70% of Nigeria's crude oil and gas production is from the area.
The oldest Precambrian rocks in Nigeria likely formed during the Archean or the Paleoproterozoic, forming the Beninian gneiss, in the Benin-Nigeria Orogen, formed during the Proterozoic Pan-African orogeny. The crystalline basement rock of the country is grouped as the Nigerian Province, a southern continuation of the central Hoggar reactivated ...
The South-South Region was created from parts of both the Western and Eastern regions of Nigeria in 1997 through the recommendation of the Alex Ekwueme panel, by the national regime of General Sani Abacha. Edo, Delta, one-quarter of Bayelsa, and the Ndoni section of Rivers states were from the old Western region.
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
