摘　　要：大庄子金矿床位于胶莱盆地与胶北地体接触带的北缘,有含金蚀变岩和含金石英脉2种矿石类型。对大庄子金矿微量元素特征的系统研究表明:大庄子金矿成矿过程主要处于中低温阶段,与Au元素关系最密切的是代表中温成矿阶段的Pb,Zn,Ag,Cu元素,以及代表低温成矿阶段的Hg元素,Au元素与低温微量元素的相关性大于与高温微量元素的相关性;大庄子金矿形成后遭受剥蚀作用不是很强,目前所开采部位主要是整个矿体的上部,其深部还有可供开采的资源量。Dazhuangzi gold deposit occurs at contact zone of Jiaolai basin and Jiaobei terrane and includes mainly altered rock and quartz vein type ores.Systematic researches on trace elements of the deposit are carried out to predict ore to its depth.The results show that metallogeny of the deposit is dominated by medium hydrothermal stage and Au is closely related to Pb,Zn,Ag,Cu representing medium temperature and Hg representing low temperature and is more closely correlated to low temperature elements than high temperture elements.The deposit is shallowly eroded and mining remains at the deposit top and considerable ore volume occurs to depth.
