Where is Benue Trough in Nigeria?
central West Africa
The Benue Trough of Nigeria is a rift basin in central West Africa that extends NNE–SSW for about 800 km in length and 150 km in width. The southern limit is the northern boundary of the Niger Delta, while the northern limit is the southern boundary of the Chad Basin (Fig. 4.1).
How was Benue Trough formed?
The Benue Trough was formed by rifting of the central West African basement, beginning at the start of the Cretaceous period. At first, the trough accumulated sediments deposited by rivers and lakes. During the Late Early to Middle Cretaceous, the basin subsided rapidly and was covered by the sea.
What is the stratigraphy of Benue Trough?
The stratigraphic succession in the Benue Trough comprises essentially thick continental and deltaic sandstones, paralic sandstones, shales, coal measures, and shallow epicontinental shales and limestone. The age of the sedimentary rocks in the Benue Trough ranges from Albian to Palaeogene.
What are the characteristics of Benue Trough?
The Benue Trough is an elongate rifted depression in which the sediments reach well over 5000 m thickness in places and have been strongly folded, probably by later adjustments along faults in the underlying basement. The Bida Basin is a shallow unfaulted arm of the Benue Trough.
How many sedimentary basins are in Nigeria?
Nigeria is underlain by seven major sedimenta- ry basins, viz: (from the oldest), the Calabar Flank, the Benue Trough, the Chad Basin, SE lullem- menden (Sokoto) Basin, the Dahomey Basin, and the Niger Delta Basin. Sedimentary succes- sions in these basins are of middle Mesozoic to Recent age.
What is Bida Basin?
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 with suspected or proven access to Cameroon, Equatorial Guinea and São Tomé and Príncipe.
How many types of basins are there?
There are five major ocean basins, coordinating with the major oceans of the world: the Pacific basin, the Atlantic basin, the Indian basin, the Arctic basin, and the Southern basin. Many smaller basins are often considered oceanic basins, such as the North Aleutian Basin, between the Pacific and Arctic Oceans.
How many oil fields are in Nigeria?
159 oil fields
Nigeria has a total of 159 oil fields and 1481 wells in operation according to the Department of Petroleum Resources. The most productive region of the nation is the coastal Niger Delta Basin in the Niger Delta or “South-south” region which encompasses 78 of the 159 oil fields.
Who created Niger Delta?
President Olusegun Obasanjo
Creation of the Niger Delta Development Commission (2000–2003) The Niger Delta Development Commission (NDDC) was established in 2000 by President Olusegun Obasanjo with the sole mandate of developing the petroleum-rich Niger-Delta region of southern Nigeria.
Where is Niger Delta in Nigeria?
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria.
What is the bathroom sink called?
A sink – also known by other names including sinker, washbowl, hand basin, wash basin, and simply basin – is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes. Sinks have taps (faucets) that supply hot and cold water and may include a spray feature to be used for faster rinsing.
What are two types of basin?
What are the different types of bathroom basins?
- Full pedestal basins. Full pedestal basins are securely attached to the wall and are good for hiding pipework and plumbing.
- Semi pedestal basins.
- Washstand basins.
- Wall hung basins.
- Corner basins.
- Countertop basins.
How big is the Benue Trough in Nigeria?
INTRODUCTION THE Benue Trough is an elongated trough of subsidence. It forms an important part of a system of linear sedimen- tary basins which includes the Niger, Benue and Gon- gola rivers. The Benue Trough has a width of 130-150 km and trends northeasterly to attain an approximate length of 800 km.
What is the evolution of the Benue Trough?
The tectonic evolution of Nigeria’s Benue Trough has recently been the focus of investigations, especially in relation to continental drift and opening of the South Atlantic Ocean during Cretaceous times.
Are there any petroleum resources in the Benue Trough?
A review on the geology and petroleum potentials of the Nigerian Benue Trough and Anambra Basin is done to identify potential petroleum systems in the basins.
How are the Benue Trough and Anambra Basin similar?
The tectonic, stratigraphic and organic geochemical evaluations of these basins suggest the similarity with the contiguous basins of Chad and Niger Republics and Sudan, where commercial oil discovery have been made.
