| 摘 要： | 河南省水洞岭铜锌多金属矿床硫同位素特征显示出海相火山岩型矿床特有的混合硫(幔源硫+海水硫)特征;矿区内铅同位素组成比较均一,在铅构造模式图上主要落在地幔及造山带之间,反映其源区以地幔铅为主,并混有造山带、上地壳铅的特征,表明其成矿物质主要来源于火山作用。由此建立该矿床的火山喷发沉积的成矿模式。

| Abstract: | The sulfur isotopic geochemical characteristics of Shuidongling Cu-Zn deposit show the mantle source + ocean water source of sulfur. The lead isotopic composition is more homogeneous, and is mainly located between mantle and orogenic belt in the lead isotopic plumbotectonics model. It reflects the main source of lead is mantle, mixed with the lead from orogenic belt and upper crust. It shows that the ore-forming materials are mainly from volcanism. So we can build the ore-forming mechanism of volcanic erupt-sediment. |
