Upward Continuation and Reduction to Equator Filters on Aeromagnetic Data of parts of Bida Basin, Nigeria

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.
