摘要
通过对吉林省东部地区小西南岔金铜矿床矿体形态、矿床蚀变类型、矿物组合及其同位素的研究,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、多类型成矿作用迭加特点。
Studies on the aspects of ore body shape,al- teration type,mineral association and isotopic charac- teristics of Xiaoxinancha gold - copper deposit,which located in eastern Jilin province,indicated that the source material of the porphyry type polymetallic de- posit come from the subducted oceanic crust,the fluid characteristic of the deposit has relation with the calc - alkaline intermediate-accid hypabysal magmatic rocks,and the deposit has a characteristic of multiple phases and multiple types of ore-forming process.
