Wulong gold deposit is a large quartz vein type gold deposit located in the middle of the Wulong ore deposit cluster. In order to ascertain the deep structure of the ore deposit cluster and to successfully guide deep prospecting prediction, it is necessary to carry out comprehensive research on deep geophysical and metallogenic characteristics. Characteristics of aviation electromagnetic field and prospecting significance of Wulong ore deposit cluster were studied based on the aerial exploration data. The aeromagnetic, airborne electromagnetic and airborne magnetotelluric properties of the Wulong gold deposit were studied from plane, profile and space, and also included the metallogenic geological characteristics. The results of the study are as following: on the plane, the orebody is located at the intersection of weak magnetic anomaly zones in the negative magnetic background field area on the east side of Jixingou fault, the turn and gradient zone of medium—strong residual magnetic anomaly zone, the low resistivity zone of apparent resistivity, the middle and low resistivity gradient zone, and the mass high apparent magnetic susceptibility zone in the deep. On the profile, the orebody is located in the apparent resistivity gradient zone with medium and low resistance, the apparent susceptibility gradient zone with the medium—weak magnetic field which is lower right and higher left. In the space, the orebody is located in the gradient zone with low and high resistance. The establishment of geological and geophysical prospecting indicators and the existence of the deep high apparent magnetic susceptibility anomaly area in the Wulong gold deposit indicated that the deep mining area in the space of 1000~2000m has good prospecting potential. However, the deep space should have similar characteristics of apparent resistivity and apparent magnetic susceptibility to the Wulong gold deposit.
