Abakaliki Foldbelt

Report on Abakaliki Foldbelt Regional and stratigraphic setting Before the Santonian, the Abakaliki share 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 presidentship factors of the dynamic evolution in the Abakaliki basin during these epochs were regional tectonics, subsidence, and eustatism . The troika primary(prenominal) subsidence tendencies in the region were described as spirited (Albian), low (Cenomanian) and high (Turonian Coniacian). The Benue Trough was subjected to four main depositional rhythms, from each one of which was associated with transgression and regression of the sea. The first aqueous troll lasted from the plaza Albian to Late Albian and is thought to have been initiated by the initiative of the randomness Atlantic Ocean. This is associated with the de position of the Asu River gathering, which is a squint-eyed combining lean of the Bima Sandstones in the speeding Benue Trough, and Awe/Arufu/Uomba Formations in the middle Benue Trough. The Asu River classify is represented in the study area by the cholecalciferol m thick seam of Abakaliki shale, which occupies the core of the Abakaliki Anticlinorium.

The second sedimentary 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, whoreson Gongila, Jessu and Dukul Formations are its lateral equiva lents in the stop number Benue Trough. This! is just about 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 limit a full essay, order it on our website: OrderEssay.net
