dc.description.abstractInterpretation of HRAM data over part over part of Northwest Nigeria has been carried out with the aim of delineating lineament structures such as faults, contacts, joints etc. and estimating the depth to the top of the magnetic basement (which is equivalent to the sedimentary thickness). This research work makes use of a Total Magnetic Intensity (TMI) acquired from Nigerian Geological Survey Agency which was part of the recent nationwide airborne magnetic survey carried out in 2010.The map was gridded into eighteen non-overlapping blocks (20 x 20 km) and each of the blocks was analysed using Spectral analysis which reveals two source depths, depth to shallow magnetic sources which ranges from 0.12 km to 0.30 km and depth to deeper magnetic sources which ranges from 0.98 km to 1.81 km. Also, the study area reveals parallel contour lineament trending NE – SW and subordinate E-W direction which are suggestive of fault and joint in the area. The result obtained from the study which reveals the depths to basement structures and delineation of lineament structures would complement the existing geophysical information of the area
