It has a subaerial area of about 75,000 km 2, a total area of 300,000 km 2, and a sediment fill of 500,000 km 3. [1] The sediment fill has a depth between 9–12 km. [2] It is composed of several different geologic formations that indicate how this basin could have formed, as well as the regional and large scale tectonics of the area. The Niger ...
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 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 upper region is further ...
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 ...
Africa’s largest economy overwhelmingly depends on the Niger Delta’s oil resources for its earnings, but pollution from that production has denied residents access to clean water, hurt farming ...
An oil spill in the fishing village of Kegbara-Dere, Rivers State on the Niger Delta. In 2016 Shell paid US$80 million for the spill [1] Petroleum extraction in the Niger Delta has led to many environmental issues. [2] [3] The delta covers 20,000 km 2 (7,700 sq mi) within wetlands, formed primarily by sediment deposition.
The Niger River (/ ˈ n aɪ dʒ ər / NY-jər; French: (le) fleuve Niger [(lə) flœv niʒɛʁ]) is the main river of West Africa, extending about 4,180 kilometres (2,600 miles). Its drainage basin is 2,117,700 km 2 (817,600 sq mi) in area. [11] Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border.
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.
