Abstract: Geomagnetic exploration techniques largely determine the subsurface geometry and spatial distribution of rock magnetization and have been used to delineate the geometry and potential zones for economic mineralization. This study used outcrops and ground magnetic data collected over parts of Hawal Massif, northeastern Nigeria to determine the subsurface spatial distribution of rock magnetization and potential bearing zones for local mineralization. The geological investigation shows that the Hawal Massif is predominantly underlain by the Precambrian Basement rocks that include granites, gneisses and diorites. These rock units are largely affected by tensile and shear fractures. The latter largely trends in the NE-SW and NW-SE directions. The results also demonstrate that the geometry and potential targets for local mineralization consistently correlate with positive local maxima in total magnetic intensity (TMI) anomalies - those recording residual magnetic values between 180 nT and 350 nT. These zones of local total magnetic intensity (TMI) maxima occurred around Chicago, Jalingo Maiha and Dumo areas and thus represent potential target zones for local mineralization. Consequently, recognizing the effectiveness of ground magnetic data is crucial, as it provides information on the geometry and potential bearing zones for local mineralization, a parameter directly affecting selection of sites for detailed geological mapping, mineral resource assessment and mining activities.
