Abstract
Ground magnetic survey of Ijeda and Iloko towns in Oriade Local Government Area of Osun state Southwest Nigeria was performed. The study was carried out using high resolution proton precision geometric magnetometer which involves the use of Total Component of the ground magnetic anomaly data running through traverses 7, 8, 9 and 13. This research focuses on delineation of faults in this part of the highly mineralized Ilesa schist belt. The field data was qualitatively and quantitatively interpreted and the results gave values for the Total component measurements of ground magnetic anomaly which varied between a minimum negative peak value of about -330 gammas and a maximum positive peak value of about 80 gammas. Depth to the basement rock was estimated using half slope method. Information on wide range of magnetic intensities over the different rock types in this area were obtained from the quantitative interpretation using linear trends. The results generated were used to delineate rock boundaries, bedrock topography major and minor faults.
