Abstract:

The ground magnetic studies of Ijebu-jesa town in Oriade local government area of Osun State Southwestern Nigeria were carried out to study the subsurface geology of the area. The Total Component Magnetic Intensities data was interpreted. The qualitative interpretation of the ground magnetic data showed varying magnetic intensities over the different rock types in this area from the approximation of the geologic boundaries were delineated. Also the quantitative interpretation resulted in generation of geomagnetic section using linear trends gives magnetic intensity values that vary between about -250 nT to about 300 nT. Depth to the basement rock was estimated using slope techniques this allow s the Lateral and Depth estimates of different rock types to be determined. Also basement structures such as bedrock topography; bedrock depression; rock boundaries, contact zone, fractures/faults were delineated which serve as deposits centers’ for mineral resources. The trend analysis was used to produce a residual magnetic map which allows better mapping of Iwaraja fault as seen on Amphibolites schist.
