What are the characteristics of Benue Trough?

What are the characteristics of Benue Trough?

Summary. The Benue Trough is an elongate rifted depression in which the sediments reach well over 5000 m thickness in places and have been strongly folded, probably by later adjustments along faults in the underlying basement. The Bida Basin is a shallow unfaulted arm of the Benue Trough.

What is the stratigraphy of Benue Trough?

The stratigraphic succession in the Benue Trough comprises essentially thick continental and deltaic sandstones, paralic sandstones, shales, coal measures, and shallow epicontinental shales and limestone. The age of the sedimentary rocks in the Benue Trough ranges from Albian to Palaeogene.

What is middle Benue Trough?

Middle Benue Trough is a moderate to deep, fault bounded rift basin with thick (~ 6304 m) Cretaceous sediments. Imaged sub-basins, elongated basement ridges and structures exhibit NE-SW, ENE-WSW, NNE-SSW and NW-SE major trends.

How was Benue trough formed?

Rifting and sedimentation The Benue Trough was formed by rifting of the central West African basement, beginning at the start of the Cretaceous period. At first, the trough accumulated sediments deposited by rivers and lakes. The trough is estimated to contain 5,000 m of Cretaceous sediments and volcanic rocks.

When was Benue created?

February 3, 1976

As an administrative unit, Benue State was first created on 3 February 1976. It was one of the seven states created by the military administration headed by General Murtala Mohammed, which increased the number of states in the country from 13 to 19.

What is the evolution of the Benue Trough?

The tectonic evolution of Nigeria’s Benue Trough has recently been the focus of investigations, especially in relation to continental drift and opening of the South Atlantic Ocean during Cretaceous times.

Is the middle Benue Trough in Nigeria mapped?

The Middle Benue Trough Although some sections of the Middle Benue area have been mapped, most of what is known as the Middle Benue Trough still remains unmapped in any detail.

Is there a crystalline basement in Benue Trough?

In the Lower and Middle Benue areas, the crystalline basement, whose topography is believed to be irregular (Cratchley and Jones, 1965; Effeotor, 1974; Ayoola, 1978), is exposed in a number of places. It comes quite close to the surface at a few other places.

Are there any tectonic models for the Benue depression?

Most of the tectonic models presented for the Benue depression have placed undue emphasis on certain plate tectonic concepts which are inconsistent with the salient geologic features of the trough.
