What is Upper Benue Trough?
The Upper Benue Trough of Nigeria is the northeastern most portion of the Benue rift structure that extends from the northern limit of the Niger Delta in the south to the southern limit of the Chad basin int he northeast. this portion of the trough is made up of two arms: the Gongola Arm and the Yola Arm.
How is Benue Trough formed?
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. During the Late Early to Middle Cretaceous, the basin subsided rapidly and was covered by the sea.
What are the characteristics of Benue Trough?
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.
