Qualitative and quantitative interpretations of aeromagnetic map over part of the Southern Bida Basin, West-Central Nigeria have carried out using spectral analysis. The aeromagnetic maps digitized along flight lines of 2km interval. The qualitative interpretation of the magnetic anomaly and first vertical derivative maps revealed that the area is intensely faulted with major faults trending East-West (E-W) and minor ones Northeast-Southwest (NE-SW) directions. The result obtained using the spectral method reveals two depth sources in the area, the deeper sources range from 2.81 to 3.24km, while the shallower sources range from 0.45 to 1.49km.The result also shows a linear depression with sedimentary accumulation trending E-W. The average sedimentary thickness in the region is about 2.90km.
