The Normalized Full Gradient (NFG) method was introduced in the mid of 1960s. This method generally uses for interpretation potential field data in order to detect gravity and magnetic anomalies. The NFG value represents the full gradient of the magnetic anomaly at a point divided by the average of the full gradient at the datum. The closed maxima on a NFG map indicate the occurrence and the horizontal locations of the centers of magnetic anomalies related to iron deposits. By means of this map, we can select bore...
