The source parameter imaging technique was used for the composite Ekiti State’s aeromagnetic data to determine the depth of the magnetic basement at different locations in the research area. Determining basement depth in this type of terrain is essential for groundwater exploration which is crucial for sustenance of life. The aeromagnetic data covering the entire state were processed using the oasis montaj 8.4 software. Firstly, the first order polynomial fitting method was used for the regional – residual separation of the total magnetic field intensity data before the application of the reduction to equator transformation filter on the residual component. The data were further enhanced by using upward continuation smoothing filter to remove the effect of the short-wavelength noise from the data. The depth of the magnetic basement, derived from the source parameter imaging technique, ranges from 116 m to 658 m, which indicate the depths to the top of the magnetic sources within the basement rocks in the study area.
