BENUE TROUGH PDF

The Benue Trough is an elongate rifted depression in which the sediments reach well over 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. The Niger Delta at the southern end of the Benue Trough has been building out into the Atlantic since the end of the Cretaceous. Of the other coastal basins, the Senegal Basin is by far the largest, but the basins along the southern coast of West Africa are larger than their surface extents suggest, as substantial parts of their successions are offshore.

Benue Trough

The origin and peculiarities of the nigerian benue trough : Another look from recent gravity data obtained from the middle benue. The origin of the Benue trough has been a controversial subject. Previous workers in the area have evolved several theories ranging from a rift, with or without plate tectonic concepts King, ; Wright, , ; Burke et al. One of the aims of the gravity survey, carried out in the middle Benue and discussed in this paper, was to attempt to resolve some of the problems associated with the origin of the trough as proposed by previous workers and in so doing to explain the geological peculiarities associated with the trough. Interpretations of the gravity data along two north—south profiles in the survey area indicated the existence of a rift, of normal width about 40 km buried under the Cretaceous cover and located between the central axis ridge of the trough and the northern boundary of the trough.

The southern limit is the northern boundary of the Niger Delta, while the northern limit is the southern boundary of the Chad Basin Fig. The trough contains up to 6, m of Cretaceous — Tertiary sediments of which those predating the mid-Santonian have been compressionally folded, faulted, and uplifted in several places. Compressional folding during the mid-Santonian tectonic episode affected the whole of the Benue Trough and was quite intense, producing over anticlines and synclines Benkhelil,
