Abstract

This paper seeks to model the ground magnetic field data acquired around the Schist belt areas of Kano State in order to extract the causative body parameters. The only parameter estimated from previous work using the same data, is the depth to the causative body and hence the need to estimate other parameters. Six profiles cutting through both high and low anomalous zones were drawn on the residual map; mag2DC software was used to model the data. The parameters obtained from the modeling include body center, maximum width, depth-to-body, depth extent and susceptibility, with their values ranging from 50.94 m to 606.57 m, 4.48 m to 200.72 m, 7.46 m to 150.75 m, 82.09 m to 465.61 m and -0.0879 to 0.1043, respectively. The value for depth-to-body from this work was compared with those of previous works and found to agree fairly well. The susceptibility values suggest that the study area comprises of iron and chromium rich minerals as well as quartz. It is recommended that geochemical analysis should be carried out on rock samples in the study area to ascertain the actual minerals present.
