Abstract The geological conditions in Xizhangyong area of Zhangbaling zone are complex. In order to find out the stratum distributions and structure conditions, based on the regional gravity and magnetic data, the author inferred the regional fault structure distribution, and studied the distribution range and morphological characteristics of rock mass in the area. In order to investigate the Au-Ag-bearing quartz keratophyre veins in the structural belt of Xileng Formation of Zhangbaling Group in this area, the author processed the magnetic anomaly data measured on the ground to extract comprehensive geophysical anomalies favorable for prospecting target areas, using the IP mid-elevator, gravity-magnetic profile and high-power IP sounding surveys. Combined with the interpreted characteristics of comprehensive geophysical anomalies, the results showed that synthetical geophysical anomalies in the area were caused by the veins intruding into Laosanjie-Guandian NW syncline structure in Xileng Formation of Zhangbaling Group. The lithology in the area was mainly quartz keratophyre in Xileng Formation of Zhangbaling Group, which was the main basis for searching for gold-silver-bearing quartz veins in Zhangbaling Group. This study provides a reference for deep prospecting, peripheral prospecting and primary selection of prospecting targets in Xizhangying area.
