Application of Remote Sensing Interpretation to Metallogenic Prognosis of Gold Deposit in Xiqingshan Area

Due to the fact that gold deposits in the Xiqingshan area is significantly controlled by tectonic structures, studying the structure of this area is the key of metallogenic prediction. In this paper, based on field geological investigation and remote sensing interpretation method, we studied the remote sensing geology and the gold distribution regulation of the Xiqingshan area. The results showed that: in the Xiqingshan area, a NWW gold deposit belt was formed, west from the Nanmurang, by Zhongqu and Dashui gold deposits, east to the Junmuchang. There are four gold ore fields equidistantly in this gold deposit belt. From west to east, they are Nanmurang gold ore field, Zhongqu gold ore field and Dashui gold ore field. Each of them has a number of gold deposits and gold ore occurrence. The Junmachang area in the east is the centralized area of remote sensing mineralization information, and may become a potential gold ore field. In each ore field, the favorable position of gold deposit is the centralized interchange of the NWW faults with the NW, NNE and NE fault, and near the edge of the ring structure. On this basis, we predicted 7 favorable metallogenic zones.
