Ground Magnetic Study for Characterization of Mineral Potential in Alajawa Area in Shanono, Kano State, of Nigeria

Abstract

The ground magnetic survey was carried out using a Scintrex proton precession magnetometer to map out subsurface structures and mineralization potentials at the Alajawa area in Shanon, Kano State. 2D forward modeling was in the delineation of geological structures that are potential mineralization zones. Surfer 15 software was used to produce a residual contour map. A total of five (5) profiles of the magnetic residual anomalies were modeled using Mag2dc software. The mineral potential locations were identified. The major zones with the potential of mineral resources were located at the depth of 14.81m, 1.71m, 10.83m, 14.25m, and 15.38m along profile AA’; 3.42m, 10.01m, 15.95m, 7.41m, and 2.28m along with profile BB’; 20.51m, 11.97m, 2.28m, and 27.35m along with profile CC’; 3.99m, 2.85m, 5.13m, and 6.27m along with profile DD’; 34.76m, 25.64m, 7.98m, and 8.55m along profile EE’. The bodies display susceptibility as high as 5.3380 SI Units and as low as -06.745 SI Units. The results of the research analysis revealed that the subsurface is composed of limestone, sandstone, and shale, granite or rhyolite rocks, gneiss, schist, slate, and quartzite.
