| 摘 要： | 本文系统地研究了扬子地台北缘中段中上元古界中金银矿床的硫、铅、碳、氢、氧同位素组成。研究表明:银洞沟Au-Ag-Pb-Zn矿床、许家坡Au-Ag-Te矿床和白岩沟Au矿床的成矿物质具深源特征,成矿流体为混有少量大气水和岩浆水的变质流体;东沟坝Au-Ag-Pb-Zn重晶石型矿床成矿物质及成矿流体皆具多来源的特征。

| Abstract: | Compositions of S, Pb, C, H, O of gold-silver deposits in the Middle-
Upper Proterozoic Suberathem in the middle section of the northern margin of
Yangtze Platform bare been systematically studied in this paper. Studies show
that ore-forming materials of Yingdonggou Au-Ag-Pb-Zn deposit, Xujiapo
Au-Ag-Te deposit and Beiyangou gold-bearing quartze vein deposit have cha-
racteristics of deep source; ore-forming fluids of them are metamorphic fluid
and a mixture of a small quantity of magmatic water and meteroic water. Ore-
forming material and ore-forming fluid of Donggoubar Au-Ag-Pb-Zn-barite
deposit both have characteristics of multi-source. |
