Abstract

The ground magnetic studies of Ijebu-jesa town in Oriade Local Government Area of Osun State Southwestern Nigeria was carried out which involves the use of Horizontal Components (i.e. horizontal magnetic intensities and horizontal magnetic gradients). The field data was qualitatively and quantitatively interpreted and the results give values for horizontal magnetic intensity that varied between a negative peak magnetic anomaly of about -800 gammas to a positive peak magnetic anomaly of about 1800 gammas. While the horizontal gradient give values that varied between a negative peak magnetic anomaly of about -500 gammas to a positive peak magnetic anomaly of about 500 gammas over the different rock types in this area. The magnetic values obtained from the linear trends analysis varied between a negative peak magnetic anomaly of about -100 gammas to a positive peak magnetic anomaly of about 120gammas. Depth to the basement rock was estimated using half slope method. The results generated were used to construct geomagnetic sections from where rock boundaries, bedrock topography major and minor faults were delineated.
