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 ...
The Liptako area in the northeast is the terminus of the West African gold belt, which extends from the Atlantic in Ghana. It hosts gold in the Birimian greenstones of Tera-Gasso and Gorouel belts. The gold belt actually extends further east, past the Niger River, but is largely concealed by younger sediments and sedimentary rocks.
The delta consists of the middle course of the Niger River, between the bifurcated Niger and its tributary the Bani, which from here run north towards the desert. The Niger is the longest river in West Africa. Towns such as the river-port of Mopti, Sévaré and Djenné, with its mud-brick Great Mosque lie in the 400 km-long region.
The Niger Delta is located in the southern part of Nigeria. It is one of the world's largest arcuate fan-shaped river deltas. The riverine area of the Niger Delta is a coastal belt of swamps bordering the Atlantic.
An unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. [20] The result is a region of braided streams, marshes, and large lakes; the seasonal floods make the Delta extremely productive for both fishing and agriculture.
