摘要
青海尕什江铅锌矿位于互助县松多乡与乐都县引胜乡交界处,为热液型铅锌矿。该文介绍,通过硫同位素研究,获得尕什江铅锌矿中的10件金属硫化物样品(黄铜矿、方铅矿、闪锌矿、磁黄铁矿)δ34S‰值变化于-10.975‰^-2.490‰,平均-8.353‰。在硫同位素组成频率直方图上,其分布呈峰式分布,一个峰值在-11‰~9.0‰,一个在-8.5‰~7.5‰,另一个在-7.0‰~6.5‰,说明矿床硫源具有混合来源特征。
The Gashijiang Pb-Zn deposit in Qinghai Province lies on the north margin of the central uplift belt of the middle Qilian orogenic belt.It is a hydrothermal type Pb-Zn deposit.δ34S values for chalcopyrite,galena and sphalerite from this deposit vary from-10.975‰to-2.490‰with average of-8.353‰indicating mixed sulfur source.
