Abstract
To enhance the aeromagnetic maps covering six data sheets encompassing the Mokwa, Egbako, Bida, Lafiagi, Pategi, and
Baro regions of the Bida Basin, Nigeria, this research employs two magnetic filtering techniques. The aim is to refine the
maps for a better representation of the study area. The study intends to improve the interpretation of aeromagnetic data by
better identifying depth discrepancies and differentiating between shallow and deep-seated magnetic sources within the
surveyed region using upward continuation (UC) and reduction to the magnetic equator (RTE) filters. Variations in anomalies
observed in both total magnetic intensity and reduction to the equator can be attributed to lithological differences, depth
variations, strike angles, magnetic susceptibility variations, or the presence of basement complex rocks with varying
concentrations of magnetic materials.
