| 摘 要： | 小西南岔金铜矿床是吉林省东部斑岩型多金属矿床之一。通过对该矿床矿体产状、矿床蚀变类型、矿物组合及其同位素特征的研究，结果表明：斑岩型多金属矿床成矿物质来源于俯冲的洋壳，矿床的流体特征基本上反映与钙碱性中酸性浅成花岗岩有关，矿床的形成具有多期、多类型成矿作用叠加特点。

| Abstract: | Xiaoxinancha gold-copper deposit is one of the porphyry type polymetallic deposits in eastern Jilin province. Through the research on the aspects of ore body occurrence,alteration type,mineral association and isotopic characteristics of the deposit,it is indicated that the source material of the porphyry type polymetallic deposit comes from the subduction oceanic crust,the fluid characteristic of the deposit is relative to the calc-alkaline intermediate-acid hypabyssal granite,and the deposit has a characteristic of multiple phases and multiple types of ore-forming process. |
