A magnetic survey of Ibadan area in the South-Western part of Nigeria was performed as part of the largest
airborne geophysical survey blocks flown between 2003 and 2010 by the Nigeria Geological Survey Agency. Two
magnetic data enhancement procedures were employed to determine their effectiveness in characterizing the study
area. The upward continuation together with reduction to Pole technique significantly improve the interpretation of
magnetic data in terms of discriminating between shallow and deep magnetic sources within the study area.
