Based on the data of 1:50 000 helicopter electromagnetic and magnetic comprehensive survey in Longmen, Guangdong Province in 2005, in combination with the geological and mineral sources data, the authors analyzed and studied the relationship between the mineral resources and the aeromagnetic or aeroelectromagnetic anomaly characteristics in Longmen area. The local aeroelectromagnetic anomalies were classified by using the classification method for electromagnetic anomaly characteristics, and the anomalies resulting from electromagnetic interference were identified. Based on field inspection of three optimized local anomalies, the authors found that the air and ground anomalies are well consistent with each other. In addition, some significant good underground conductors were detected.
