Interpretation of Airborne Previous HitMagneticNext Hit Data of Upper Benue Trough, Northeastern Nigeria

Abstract

Abstract

Airborne Previous HitmagneticNext Hit anomaly data over the triple junction of the upper Benue Trough, Northeastern Basement complex Nigeria, shows complicated arrangement of long wavelength anomalies, with significant Previous HitmagneticNext Hit low. The study of airborne maganetic data revealed some features that are interpreted in terms of deep geologic structures with variation in susceptibility of the basement rocks of thick cretaceous sediments. The NE-SW trending of the lineament map identifies the same trending of the Benue Trough. Such same trending may be inferred to have the same subsurface structural control. The residual Previous HitmagneticNext Hit anomaly map towards the S-W region which is the location of Dong and Numan is smoother, which is masked off by the effect of the stronger Previous HitmagneticTop basement likely to be sedimentary basin. The NE-SW revelation shows that this basement region is polygenetic, and has experienced magmatism, metamorphism and structural deformations caused by Pan-Africa Orogeny.
