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.
