Structural architecture of the Middle Niger Basin, Nigeria based on aeromagnetic data: An example of a non-volcanic basin

The Middle Niger Basin is located within the west-central half of Nigeria, as a NW-SE trending Campano-Maastrichtian depo-centre which extends from southern end Sokoto west Kainji reservoir southwestwards to convergence Benue and Rivers at Lokoja. aeromagnetic anomaly data was interpreted characterize structural architecture depth magnetic basement basin. This expand current knowledge region. analysis has been facilitated by application derivative source parameter imaging techniques. results total gradient provided here signify rift origin basin fault systems in surrounding complex terrain. absence highs on first vertical reduced-to-pole reveals lack volcanic rocks sedimentary layers Additionally, consistent solutions confirm internal geometry orientation with sediments not more than 1100 m thick.
