Through 1∶50 000 stream sediment survey, multi-element anomalies were delineated in Yelanggou, which included Ag, Mo, W, Zn, Bi, As, Sb, Au, Cu etc. Of all these elements, Ag, Mo, Zn, W, As and Sb anomalies have high peaks, high values and continuity. The mixed anomalies are controlled obviously by faults and folds, characterized especially by high values in well developed fault tectonic alteration zone. Areas of lithogeochemical anomalies of indicator elements are not large; nevertheless, the intensity of principal ore-forming element Zn is high, as shown by Zn11 primary halo. The area of Zn11 primary halo is 0.11 km2, the geometric mean is 1 368.51×10-6, and data of three continuous samples are all above 3 000×10-6, so this primary halo is identified as an anomaly related to mineralization. Zn, Ag and As primary halos have larger sizes and are more continuous around the mineralization district than in other places of the study area. All these results are really important for the study of ore-forming process and prospecting work.
