Abstract The integrated geophysical and geochemical methods were adopted to detect 1:50000 stream sediment geochemical anomalies in Cuiluan area, which led to the discovery of a high-grade quartz vein type silver ore deposit in the Yichun-Tieli metallogenic belt. The anomaly combination of soil elements is composed of Ag,As,Sb,Pb and Zn, the middle gradient induced polarization is characterized by high values of apparent resistivity and apparent chargeability. Studies reveal that the ore deposit is characterized by weather resistance of quartz vein type silver ore and low value of Ag element in soil, that the quartz vein causes the high value of apparent resistivity, and that pyritization leads to the high value of apparent chargeability.
