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 the youngest and most southern sub-basin (located at the southwest boundary) in the Benue-Abakaliki trough. The Benue-Abakaliki trough represents a failed arm of a rift triple junction associated with the opening of the South Atlantic. [2] Key to understanding the Delta Field is the formation of the Niger Delta.
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 ...
More than 90% of Sri Lanka's surface lies on Precambrian strata, some of it dating back 2 billion years. [6] The granulite facies rocks of the Highland Series (gneisses, sillimanite-graphite gneisses, quartzite, marbles, and some charnockites) make up most of the island and the amphibolite facies gneisses, granites, and granitic gneisses of the Vijayan Series occur in the eastern and ...

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
Akata Formation is part of the Tertiary Niger Delta (Akata-Agbada) petroleum system located in the Niger Delta Province, of Nigeria at the Gulf of Guinea, Atlantic Ocean.. The upper Akata Formation is cited to be a primary source rock, providing Type II/III kerogen, [1] and a potential target in deep water offshore and possibly beneath currently producing intervals onshore.
