Abstract
Compilation of the airborne magnetic data was conducted by digitizing along the flight line, picking the contour values across each flight line over the upper Benue Trough, Northeastern Basement complex Nigeria. It shows complicated arrangement of long wavelength anomalies, with significant magnetic low. The study of airborne magnetic 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 magnetic anomaly map towards the SW region which is the location of Dong and Numan is smoother, which is masked off by the effect of the stronger magnetic basement likely to be a 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.
