Based on a series of analytical data, this paper studied the isotopic geochemical characteristics of the Lengshuibeigou leadzincsilver ore deposit in Luanchuan County, Henan Province, so as to probe into the variation regularity of elements in the East Qinling leadzincsilver metallogenic system. The oreforming material source, the composition of oreforming hydrothermal fluids and the metallogenic environment of the ore deposit were analyzed. 40Ar39Ar dating of quartz was made, and the result shows that the silverleadzinc bearing quartz veins are products of Late Yanshanian metallogenic process. The achievements obtained are valuable in oreprospecting practice.
