Abstract：Through statistical analysis of the 1∶50 000 stream sediment survey data of Xinlin-Tayuan area, and using multidisciplinary knowledge, the authors did factor analysis and dustering analysis of the average value, standard deviation, variation coefficient, correlation of geochemical parameters and elements spatial distribution characteristics of Au, Ag, As, Sb, Bi, Cu, Pb, Zn, Mo, W, Cr, Ni, Hg. The geochemical distribution of the elements and geological significance were summarized. Via comprehensive research on typical deposit of the study area, the authors also summarized the regional metallogenic geological and geochemical conditions. Combined with the interpretation of single-element anomalies and combination anomalies, the authors supposed that it was possible to find supergene lead-zinc polymetallic ore deposits in the northern part of the ore gathering area, while the southern part was a favorable area for concealed lead-zinc polymetallic ore.
