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.
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 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 is made up of various networks of rivers and creeks mostly distributaries of the Niger River. [8] The soils of the delta vary by the shifting rivers and creeks, with sand and loam marking the remains of old levees, water-logged heavy clay in the backswamps behind the levees, and silty loam and clay on the higher ground. [ 1 ]
It encloses much of the Niger Delta, which is instrumental in the environment and economic development of the region. Geographically, the zone is divided with the Central African mangroves in the coastal far south while the major inland ecoregions are–from east to west–the Cross–Sanaga–Bioko coastal forests , Cross–Niger transition ...
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
In addition to offering a comprehensive map of terrestrial biodiversity, TEOW also provides a global species database for ecological analyses and priority setting, a logical biogeographic framework for large-scale conservation strategies, a map for enhancing biogeographic literacy, and a foundation for the Global 200.
