摘　　要：山东平度大庄子金矿发育2种矿化类型:一是蚀变破碎带型矿体,二是多金属硫化物石英脉型矿体。多金属硫化物石英脉型金矿体成矿流体以岩浆水为主,兼有大气降水参与;而蚀变岩型矿体成矿流体为岩浆水与大气降水的混合。石英脉矿化带的流体包裹体均一温度高于蚀变岩型矿化带的均一温度,较深部位的流体包裹体均一温度高于浅部。大庄子金矿目前揭露的矿体处于成矿作用发生时深度较浅、温度相对较低的部位,预测下部仍有较好的工业矿体。Two type gold mineralization occur in Dazhuangzi gold deposit in Pingdu. One is the altered cataclatic rock type and the other quartz vein type. Ore fluid of quartz vein type is dominated by magmatic water and incorporated with a little meteroic water. Ore fluid of the altered cataclatic rock type is the mix- ture of magmatic water and meteroic water. Homogenization temperature of quartz vein type fluid inclu- sion is higher than that of the altered cataclatic rock type and the temperature at deeper parts of the altered cataclatic rock type ore-body is higher than that at shallower parts. According to lower homogenization temperature measured the ore bodies mined in the Dazhuangzi Gold deposit occur at shallower environment and It is potential below the mined ore bodies.
