The Sinongduo silver polymetallic deposit is the first low sulfidation epithermal deposit found in the Linzizong volcanic rocks. Its unique origin and metallogenic geological background indicate great prospecting potential of the south Gangdise metallogenic belt. The zoning characteristics of metallogenic elements were studied by means of large scale rock geochemical survey in the Sinongduo deposit. The large coefficient of variation and standard deviation of Pb, Zn, Cd, Ag and Au indicate the high enrichment and enrichment capability of these elements. Cluster analysis shows high correlation between Pb, Zn, Cd, Ag and Au which are considered to be the main mineralization elements. Element anomalies are classified according to the cumulative frequency of 75%, 95% and 98.5% and 2 anomalies area are considered to have high prospecting potential. The authors are in the hope that the data obtained can provide a guide for the geochemical prospecting in the Gangdise metallogenic belt.
