Abstract: The purpose of the research was to identify the locations and the depth of the lineaments in the study areausing aeromagnetic and gravity data, through the investigation of its geological boundary structures. This was achieved through the processing of potential field data of Ilesha and its environs as acquired from Nigeria Geological Survey Agency. Various edge detection techniques such as First Horizontal Derivative (FHD), First Vertical Derivative (FVD), Power Spectrumand Analytic Signalmethod (ASM) were used while Euler deconvolution (ED) and Source Parameter Imaging (SPI) were applied to determine the depth and location of the lineaments generating the magnetic structures. The results shows the concentration of lineaments entrapment in southwestern part of the study area and tilted towards the center of the study area.The gravity depth range recorded in the study area is between 62.11 m and 4002.68 m from E.D analysis; and between 512.65 m and 4957.56 m from SPI. Whereas the magnetic depth recorded ranges from 1096 m to 4168 m for E.D analysis.
