How was the Niger delta formed?
The Niger Delta Basin was formed by a failed rift junction during the separation of the South American plate and the African plate, as the South Atlantic began to open. Rifting in this basin started in the late Jurassic and ended in the mid Cretaceous.
What is stratigraphy of Niger Delta?
The Niger Delta is divided into three major stratigraphic units, which are the Akata, Agbada and Benin Formations [14] . The three formations occur in each of five offlapping siliciclastic sedimentation cycles that comprise the depobelts [15,16]. …
Which of these are two major formations within Niger Delta?
Outcropping units of the Niger Delta include the Imo Formation and the Ameki Group consisting of the Ameki, Nanka, Nsugbe, and Ogwashi-Asaba formations. The subsurface lithostratigraphic units are the major transgressive marine Akata Shales, the petroliferous paralic Agbada Formation, and the continental Benin Sands.
Who created Niger Delta?
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.
What type of delta is Niger Delta?
wave-dominated delta
The Niger Delta is a wave-dominated delta located on the continental margin of the Gulf of Guinea that formed in the Paleogene. 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 km2.
When did militancy started in Niger Delta?
The current conflict in the Niger Delta first arose in the early 1990s over tensions between foreign oil corporations and a number of the Niger Delta’s minority ethnic groups who feel they are being exploited, particularly the Ogoni and the Ijaw.
What is Niger Delta known for?
The Niger delta is a vast low-lying region through which the waters of the Niger River drain into the Gulf of Guinea. Characteristic landforms in this region include oxbow lakes, river meander belts (see meander), and prominent levees. Large freshwater swamps give way to brackish mangrove…
Who is the founder of Niger Delta?
Olusegun Obasanjo
The Niger Delta Development Commission is a Federal Government agency established by Nigerian president, Olusegun Obasanjo in the year 2000 with the sole mandate of developing the oil-rich Niger Delta region of southern Nigeria.
What is the Tripartite stratigraphy of the Niger Delta Basin?
The tripartite stratigraphy of the Niger Delta Basin consists of the Akata, the Agbada, and the Benin formations. 2.2.1.2.1. The Benin Formation
What is the location of the Niger Delta?
The Niger Delta is situated in the Gulf of Guinea ( fig. 1) and extends throughout the Niger Delta Province as defined by Klett and others (1997). From the Eocene to the present, the delta has prograded southwestward, forming depobelts that represent the most active portion of the delta at each stage of its development (Doust and Omatsola, 1990).
What are the source rocks for the Niger Delta oil?
We agree with researchers (Evamy and others, 1978 among others) who believe that both formations are source rocks for the Niger Delta oil. The two formations are just different facies within the same depositional system and likely contain similar organic matter.
Where is the Late Cretaceous shale beneath the Niger Delta?
The distribution of Late Cretaceous shale beneath the Niger Delta is unknown. In the Paleocene, a major transgression (referred to as the Sokoto transgression by Reijers and others, 1997) began with the Imo shale being deposited in the Anambra Basin to the northeast and the Akata shale in the Niger Delta Basin area to the southwest ( fig. 5 ).
