Abstract: According to the 1:10,000 pedogeochemical survey results of Nanshankeng ore deposit，the geochemical characteristics of 13 elements such as W，Sn，Bi are summarized preliminarily.The results show that W，Sn and associated elements such as Bi，As，Mo are enriched in the mining area，the average value of W is 117.3×10^-6 with peak value of 7 444.2×10^-6，and the average value of Sn is 56.4×10^-6 with peak value of 2 245.9×10-6.The statistics indicates that the correlation among elements of W，Sn，Mo is strong and according to the R-cluster analysis results，main element association include W-Bi-Sn-As and Cu-U-Pb.There are 2 composite anomalies mainly which are Songganggeng-Niujiaowo and Fubeiao-Shamuwo with W-Sn belt and EW direction，and both of them acquired a good prospecting result by adopting the exposition of shallow prospecting trench and the verification of deep exploration drilling method.So，multiple skarn type tungsten tin polymetallic ore body and granite type tungsten molybdenum polymetallic ore body are found.The favorable prospecting potential of tungsten-tin polymetallic mineral deposit is indicated，thus guiding a further prospecting direction in the mining area.
