The aeromagnetic and satellite imagery data of the part of northcentral Nigeria were processed to delineate subsurface structures, produced 2D models of the structures within the study area with a view to establishing the existence of the Zungeru-Kalangai fault zone geophysically. The lineaments extracted from the Landsat-7 ETM+ imagery are dense around Zungeru, Tegina and Gidan Karauku area in the southwestern part of the study area, in the southeastern parts particularly around Chikun area and also in the northern part around Kwaimbana and Doka. The N-S, NNE-SSW and NE-SW lineament trends are prominent on the Landsat-7 ETM+. The inferred faults delineated from the aeromagnetic data showed that striking NE-SW trend is predominant. The derived composite map of the inferred faults extracted from aeromagnetic data and the surface lineaments delineated from the satellite imagery superimposed on the existing faults revealed the presence of several undetected faults cutting across the study area. The location and orientation of the Zungeru/Kalangai fault zone in the northcentral part of Nigeria which extend about 245 km, correlate with the existing fault on the published geological map of Nigeria and showed that it possibly projected to the study area through the basement within Bida Basin from the southwestern part of Nigeria. The results of the 2D models confirmed the existence of the Zungeru-Kalangai fault zone and other several new faults such as faults f3 (northern part), f4 (located around Kaya in the northeastern part of the study area), f6 and f9 (located around Sengiakun area in the northwestern part of the study area) with their approximate source locations and dips. Conclusively, these study confirm geophysically the existence of the Zungeru-Kalangai fault zone which is dipping NW and other unmapped major structures in the study area.
