摘　　要：延边地区金(铜)成矿系列的成矿流体中氢、氧同位素研究表明,其中δ18O的范围为-10×10-3～+5×10-3,δD的范围为-120×10-3～-40×10-3。小西南岔金铜矿床早期成矿流体主要以岩浆水为主,为典型的斑岩型金铜矿床;刺猬沟、五凤金矿床成矿流体主要以大气降水为主,为浅成低温热液型矿床,闹枝金矿床的成矿流体是介于上述两种类型之间的过渡型。该成矿系列的典型矿床硫、碳同位素地球化学具有幔源的特征。The research of minerogenetic fluid of gold(copper)deposit series indicates the oxyen isotope ranging from -10×10-3 to +5×10-3 and hydrogen isotope from -120×10-3 to -40×10-3. In Xiaoxinancha gold(copper) deposit,the early ore-forming fluid is mainly composed of magmatic water,with a little atmospheric water in later stage,which indicates the porphyry deposit type. Much precipicated water participated in minerogenetic period in Ciweigou and Wufeng gold deposits. Both of them are the epithermal types. The Naozhi deposit is of a transition type. The results of sulphur and carbon isotopes in the series show that they possess the mantle characteristics.
