英文摘要	An integrated geophysical and remote sensing study of ore (suspected gold) mineralisation potential of the Bode-Saadu area, southwestern Nigeria, has been conducted. Aeromagnetic data were used to infer subsurface geological features. In order to enhance the anomalies, delineate structural patterns and simplify the aeromagnetic data, first, vertical derivatives as well as horizontal gradient of the magnetic field data were performed using Oasis Montaj Software. The magnetic total field intensity anomaly map revealed that the magnetic field intensity values range from -27.9 - 131.6 nT dominated by low magnetic intensity rock characteristic of quartzite and schists while high magnetic intensities were found in the southeast, northeast and northwest parts and underlain by granite and granite gneiss. Derivatives of the magnetic field intensity data revealed NE-SW (major) and NW-SE trending lineaments. These lineaments are possibly fractures which could serve as conduits through which hydrothermal fluids flow and then fill. The application of the aeromagnetic data in the Bode-Saadu area to predict zones which have the ability to host mineralisation has shown that the technique is effective and could be applied in regional studies to pick exploration targets for unknown ore deposits.
