Abstarct: One of the most efficient methods in mineral exploration is airborne geophysics (which includes most of magnetic methods, electromagnetics and radiometry). In this method vast amounts of area could be surveyed in less time compared to other geophysical methods. Nowadays Unmanned Aerial Vehicles (UAVs) play a major role in mineral exploration, creating geological and topographical maps, and also identifying subsurface structures with more accuracy. Processing and interpretation of data acquired via magnetometers and noise elimination are major stages in mineral exploration. The goal of this thesis includes processing and interpretation of data acquired through the newest generation of magnetometers attached to UAVs. Magnetometric data used in this study have been acquired in the Sohar region of Oman. The processing stage has been done using the Oasis Montaj software. Data was acquired in two altitudes of 20 and 60 meters, in order to explore potential chromite. It should be noted that these acquisitions were carried out in order to validate the use of UAVs in mineral exploration and it is for this reason that the area of interest is on a smaller scale. The processing of data for each altitude has been carried out separately in five stages which are as follows: diurnal correction, eliminating adverse effects of magnetic anomaly displacement, heading, IGRF correction and at last, leveling. After the processing stage of the two surveying altitudes (20 and 60 meters) and producing the potential maps, the results showed that the anomalies detected at 20 meters, where not detected at the 60 meter range, and also by comparing the output results of the 60 meter range with the data of the 20 meter altitude, which an upward continuation filter of 40 meters was applied upon, it was shown that the upward continuation filter is accompanied by a small error.
