| 摘 要： | 胶东绿岩型金矿分布在绿岩带中,容矿围岩为斜长角闪岩、黑云变粒岩等。控矿构造为NWW向脆韧性断裂带,带内岩石含金平均高达58.8×10-9;成矿元素Au、Ag、As、Pb、Cu、Bi等的含量在矿体上下和蚀变带中呈有规律变化,Bi可作为近矿指示元素。硫同位素特征表明矿体与绿岩有成分上的继承关系;氢氧同位素组成反映成矿热液属变质成因。

| Abstract: | This paper discussed the general geologic characteristic of gold desposits in Jiao Donggreenstone belt at first，such as the control structure，the altcration of adjoin rock ancd soon. After that the ore－forming fluid composition and phisycal－chemical condations is anal-ysised by using trace element and isotope. |
