Abakaliki Foldbelt

Report on Abakaliki Foldbelt Regional and stratigraphic setting Before the Santonian, the Abakaliki part was angiotensin-converting enzyme of the most important depocentres in the lower Benue Trough with ocean sediments, ranging in age from Albian to Coniacian, which were deposited in the proximity of the proto-Gulf of Guinea. The principal organization factors of the dynamic evolution in the Abakaliki basin during these epochs were regional tectonics, subsidence, and eustatism . The terzetto primary(prenominal) subsidence tendencies in the region were described as mellow (Albian), low (Cenomanian) and high (Turonian Coniacian). The Benue Trough was subjected to four main depositional rhythms, apiece of which was associated with transgression and regression of the sea. The first aqueous hertz lasted from the gist Albian to Late Albian and is thought to have been initiated by the initiative of the conspiracy Atlantic Ocean. This is associated with the deposition o f the Asu River gathering, which is a lateral combining weightiness of the Bima Sandstones in the speeding Benue Trough, and Awe/Arufu/Uomba Formations in the middle Benue Trough. The Asu River assemblage is represented in the study area by the vitamin D m thick seam of Abakaliki shale, which occupies the core of the Abakaliki Anticlinorium.

The second aqueous phase occurred between the Upper Cenomanian and Middle Turonian and was associated with the deposition of Eze-Aku shale. Its lateral equivalents are the Amasiri and Makurdi sandstones in the Afikpo basin and middle Benue Trough respectively, shucks Gongila, Jessu and Dukul Formations are its lateral equivalents in the stop number Benue Trough. This is well-nigh 1 km! in thickness. The third sedimentary cycle ranged from the Upper Turonian to the Lower Santonian. It is associated with the deposition of the Awgu shale and Agbani sandstones, which are lateral equivalents of the Fika/Sekunle shale in the upper Benue Trough. The Turonian transgression, which marked the start of this cycle, is believed to have commenced from...If you want to drop dead a full essay, order it on our website: OrderEssay.net
