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. 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. Previous The essay topic. The first marine transgression in this trough occurred in the middle Albian age with the deposition of the Asu river group sediments with type locality along the banks of Asu River Reyment, Strike and dip of bed were measured and carefully plotted into the map with the aid of a protractor, ruler and pencil. Fill in your details below or click an icon to log in: Also to know the economic mineral potentials, hydrogeology, engineering geology and land use significance of the different rock types, minerals and geological features.
The Benue Trough has a lateral extent of about km in the south and includes the Anambra Basin, the Abakaliki anticlinorium and the Afikpo syncline. Reyment described the litho and biostratigraphy of the Asu River Group with its type locality along Asu River. Meanwhile from the acquired geological and logged core data, the following were done: The tectonic highs received comparatively thinner sediments and were even non-depositional in places. There are folds which consists of series of anticlinorium and synclinorium suggesting that there was a deformational episode in the trough.

Literature review of the lower benue trough
Notify me of new comments via email. Azimuth of rveiew fractures was equally measured with their dip direction and dip amount. Benue Trough is defined as an intercontinental cretaceous basin about km in length stretching in NE-SW direction and resting unconformably upon the Precambrian basement.
These volcanic rocks are best exposed in the area round the interpretation of the literathre rock types encountered, to reconstruct and interpret their depositional environments and paleogrography by using the various lithofacies, their stratigraphic relationship, structures and sedimentological character and paleontology.
It consist of dark shales and mudstone with occasional thin beds of sandy shales and sandstones. Murat proposed three major tectonic phases which took place in Albian, Santonian and late Eocene or early Oligocene times. Contacts were delineated using lithologic difference.

The aptian sediment is presented by the Ogoja sandstones. Skip to content Home About Contact. Its lithostratigrahic pile includes sandstone, siltstone, shale and limestone occurrences, Reyment These folds, coupled with the identification of the igneous rock such as andesites in the Abakaliki area which led some workers to propose a compressional subduction rather than an extensional tectonic setting for the Benue trough Farrington ; Burke et al.
The geology of the Indus Basin is closely tied to the concept of continental drift. Email required Address never made public.

The first marine transgression in this trough occurred in the middle Albian age with the deposition of the Asu river group sediments with type locality along literaturee banks of Asu River Reyment, The sediments consist of rather poorly bedded sandy shales with sandstone and sandy —limestone lenses.
The second is found only in the south of the trough, and may belong to a period when the extension of the Atlantic had slowed down, ending with a period of compression. The Anambra Basin in the west of the lower region is more recent than the rest of the trough, being formed during a later period of compression, but is considered part of the formation.

The lower which is the southern Benue Trough, is the southwestern part of the Benue depression Carter et al. These are mined in Enugu State. The Santonian age was heralded by a tectonic event. Ttrough Benue Trough has a lateral extent of about km in the south and includes the Anambra Basin, the Abakaliki anticlinorium and the Afikpo syncline.
The rock units were logged and interpreted. The Turonian is overlain by sediments of Coniacian age. The Benue Trough is a unique rift feature on the African continent in that it occupies an intracontinental position and has a thick literaturw folded Cretaceous supracrustal fill Cratcheley and Jones ; Wright ; Grant ; Burke et al. The mapping exercise was carried out with the help of the geological materials and equipments.
The floor reviwe the Basin is irregular and sediments thicknesses vary from place to place. Regional stratigraphy and sediment thickness patterns were thereafter strongly modified by reviw Lower Santonian tectonism in the lower Benue Trough. The first is prominent in the north of the trough, and contemporary with magmatism in Brazil, probably occurring during a period of crustal extension before the Atlantic started to open.
Regionally, the mapped area is within the Southern end of the Benue trough. This tectonic epirogenic event led to the uplift, folding and widespread erosion of the pre-santonian sediment in the trough. The third and last period is also found only in the south of the trough, and may be related to an litdrature response to the earlier crustal thinning. Important geological features were photographed and fresh representative samples were collected.
