  An integration of Landsat-7 ETM+, DEM and aeromagnetic datasets was used for basic surficial geologic mapping of the area of study. False colour composite and principle component analysis were derived from three separate bands each with same spatial resolution of 30 m, superimposed over one another. Visible and infra-red waves of the electromagnetic spectrum were sent out to the surface/near surface and the received impulses reveal areas with varying magnetic susceptibilities, displayed on the first vertical derivative map and areas that emitted ranges of heat radiation signatures, displayed on the analytical signal map. Lineaments were conversely extracted from these maps over an area of about 770 km2. These lineaments represent fractures, faults, discontinuous quartz ridges, river channels, trenches and furrows in field. The eastern major fracture is the Kalangai major fault trending N..
