DELINEATION OF MINERAL POTENTIAL ZONES OVER KEFFI – ABUJA AREA IN NORTH-CENTRAL, NIGERIA USING AEROMAGNETIC DATA

Abstract

Aeromagnetic data over Keffi-Abuja,North-central Nigeria bounded by latitudes N08o50′, N10o00′ and longitudes E07o00′ and E08o00′ were obtained with the aim of delineating the mineral potentialzones and structural lineaments in the area. The data was subjected to series of processing to enhance the interpretation. First and second vertical derivatives filters were applied to the data to enhance shallow features. The result obtained revealed a NE-SW trend as the dominant trend of the structures of the shallow anomalies with a less dominant E-W and NW-SE trends and also the central to Western part around the Kagarko, Kafin and Abuja area are particularly promising for mineral prospecting
