【摘要】：江永银铅锌矿床是钦-杭Cu-Au-Pb-Zn-Ag多金属成矿带内典型的矽卡岩型矿床,矿床位于铜山岭岩体西部,产于岩体与围岩的接触带及其附近。矿石中金属矿物以方铅矿、闪锌矿、磁黄铁矿、黄铁矿为主。矿石金属硫化物的S、Pb同位素组成分析显示,δ~(34)S值变化范围为0.1‰~3.6‰,平均值1.7‰,组成极为均一,指示硫主要来自岩浆;矿石铅同位素组成比较稳定,~(206)Pb/~(204)Pb、~(207)Pb/~(204)Pb、~(208)Pb/~(204)Pb值变化范围分别为18.776~18.953、15.724~15.847和39.017~39.448,平均值分别为18.884、15.775和39.224,与铜山岭花岗闪长岩铅同位素组成相似,具上地壳铅特征。江永银铅锌矿床成矿物质主要来自深部岩浆热液。

The deposit is located in the west of Tongshanling rock body and occurs in and near the contact zone between rock mass and surrounding rock. The metallic minerals in ore are galena, sphalerite, pyrrhotite and pyrite. The analysis of the isotopic composition of ore metallic sulfides shows that the 未 ~ (34) S value varies from 0.1 鈥，
