Summary

About 300 gravity stations were established at 2–4 km intervals along an E-W profile across the Lower Benue Trough from Gboko-Nsukka-Auchi with the main objectives of investigating the nature and configuration of the basement complex underlying the trough and estimating the thickness of the sedimentary cover rocks. The resulting Bouguer anomaly profile shows a series of alternating positives and negatives. For a preliminary interpretation, the positive anomalies are attributed to shallow basement and the negative anomalies to sediment-fill of maximum thickness, 4250 m.
