This occurs as a result of extensive block faulting initiated when the trough began to develop. The formation consists of bluish grey, well bedded shales. Check if you have access through your login credentials or your institution. Shortly after the break up of African and South America, a continental condition favourable for the deposition of fluvio- deltaic sediment which occurred in the Albian age. A minor transgression occurred in late Maastrichtian with the deposition of Nsukka formation. Literature review of the lower benue trough Breakthrough Physics:
Reyment described the litho and biostratigraphy of the Asu River Group with its type locality along Asu River. It is also the oldest dated sedimentary rock unit in southern Benue Trough Whiteman, Notify me of new comments via email. The geology of the Indus Basin is closely tied to the concept of continental drift. Murat proposed three major tectonic phases which took place in Albian, Santonian and late Eocene or early Oligocene times. The Southern Benue Trough is part of the Benue depression which comprises mainly the Abakaliki Anticlinorium and Afikpo syncline to the east and the Anambra basin to the west. The lower which is the southern Benue Trough, is the southwestern part of the Benue depression Carter et al.
The formation consists of bluish grey, well bedded shales. The sediments consist of rather poorly bedded sandy shales with sandstone and sandy —limestone lenses. View all posts by colbybernal It is the present work should contribute towards a general and broad understanding of the geology of bebue Benue Trough.
Literature review of the lower benue trough
These folds, coupled with the identification of the igneous rock such as andesites in the Literathre area which led some workers to propose a compressional subduction rather than an extensional tectonic setting for the Benue trough Farrington ; Burke et al. Meanwhile from the acquired geological and logged core data, the following were done: Also to know the economic mineral potentials, hydrogeology, engineering geology and land use significance of the different rock types, minerals and geological features.
A minor transgression occurred in late Maastrichtian with the deposition of Nsukka formation. Skip to content Home About Contact.
These beds have been assigned as the Odukpani Formation Reyment, The faults extend into the ocean with the Chain and Charcot fault zones, and have their counterparts in northeastern Brazil. Integrations litedature all the data and its interpretations reveal the trend and structure that controls the mineralization, mineralogy and the sequence of deformation.
Later, the deep layer of vegetation became buried under coarse sands. Reyment,Ofoegbu, By Frederick K Onu. You are commenting using your Twitter account.

Based on the trough corresponding geological and geomorphologic partition, it is subdivided into the upper, middle and lower region. Reyment described the litho and biostratigraphy of the Asu River Group with its type locality along Asu River.
It is also the oldest dated sedimentary rock unit in southern Benue Trough Whiteman, You are commenting using your Behue account. They, however, constitute favourable regions for developing petroleum entrapment structures and stratigraphie pinchouts.
The beds, rich in ammonite fauna, indicate Albian age. Its lithostratigrahic pile includes sandstone, siltstone, shale and limestone occurrences, Reyment The third and last period is also found only in the south of the trough, and may be related to an isostatic response to the earlier crustal thinning. The detailed mapping includes the measurement of strikes and dip of the formation, azimuths of the fractures, descriptions of the rock unit literaturs delineation of its contacts using lithologic difference; study of the rock type, sample collection and logging of the unit.
