Total-field aeromagnetic data over the western half of the Bornu basin and its surrounding areas were analyzed using angular spectral analysis, upward continuation and lowpass filtering techniques. Results revealed several angular spectral peaks at various angular orientations. The angular orientations correlated with the trends of the deep-seated NNW-SSE, NW-SE, NNE-SSW and NE-SW regional lineaments inferred from the upward continuation and lowpass filtering techniques. Superposition of the inferred regional lineaments on the surface geology suggests that the inferred lineaments exerted structural control on the magmatism, sedimentation pattern and the flow pattern of the Gongola river in the study area.
