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 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 delta is fed with sediment from the Niger River, which has the ninth largest drainage area in the world and the third largest in Africa at 2.23 million km 2. [ 5 ] [ 6 ] The delta is 75,000 km 2 in size and reaches a maximum thickness of 12 km in the center of the basin. [ 7 ]
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 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 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 apparent deadlock stems from mistrust and past grievances in the riverine and oil-abundant Niger Delta region, which is mostly home to minority ethnic groups who accuse the Nigerian government ...
It is in the Inner Niger Delta of the Niger River. During high water stages of the river, the delta formed by lakes, creeks, and backwaters form part of Lake Débo. The inner delta has many wide channels, which are shallow and flooded marshes; this delta extends over a length of 320 kilometres (200 miles) with a width of 80 km (50 mi).
