依据一系列样品的测试数据,对河南省栾川县冷水北沟铅锌银矿床同位素地球化学特征进行分析研究,以反映东秦岭铅锌银矿床成矿系统中的元素变化规律,主要分析了矿床的成矿物质来源、成矿热液的组成以及成矿环境的变化等.利用石英 ~(40)Ar-~(39)Ar年龄测定,求得矿床含银铅锌石英脉是燕山晚期成矿过程中的产物,这在找矿实践中具有较高的利用价值.

Based on a series of analytical data, this paper studied the isotopic geochemical characteristics of the Lengshuibeigou lead-zinc-silver ore deposit in Luanchuan County, Henan Province, so as to probe into the variation regularity of elements in the East Qinling lead-zinc-silver metallogenic system. The ore-forming material source, the composition of ore-forming hydrothermal fluids and the metallogenic environment of the ore deposit were analyzed.~(40)Ar-~(39)Ar dating of quartz was made, and the result shows that the silver-lead-zinc bearing quartz veins are products of Late Yanshanian metallogenic process. The achievements obtained are valuable in ore-prospecting practice.
