Application of Thin Sheet Model for the Analysis and Interpretation of Aeromagnetic Data
J.A. Adegoke and G.O. Layade

Abstract:
An aeromagnetic map for Ogbomoso area within longitudes 4°00 and 4°30'E and latitudes 8°00 and 8°30'N which covers the distance of 55 by 55 km (3025 km2) study area was acquired. The map was digitized, gridded and delineated into profiles at 100 m interval of which some profiles were selected, processed and regional gradient removed. Reduction-to-pole of the total magnetic field intensity was carried out, the contour map and surface distribution of the magnetic minerals was obtained using semi-automated geophysical software. To carry out a quantitative analysis and interpretation thin sheet model was used to study the magnetic anomaly of the area and subsequently determine the average depth to the magnetic mineral source, magnetic angle and the angle of dip. The results obtained reveals 150-265.2 m of depth with combined magnetic angle of 39.8-53.1° and angle of dip of 66.9-81.3°, respectively. The result from the analysis indicates the presence of magnetic mineral resources in the locality which spread across the surveyed area while some are found at fairly near-surface, others are located at a deep region of the crust.
