| 摘 要： | 山东牟乳金矿带位于华北地台东缘活化区。区内荆山群和胶东群变质绿岩建造是金矿化的矿源层。区内主要控矿构造为北北东、北东向构造。金矿床主要为含金硫化物石英脉型。成矿流体来源于地壳深部和后期大气降水的加入。对矿带成矿演化机理的研究表明，金矿形成经历了 3个阶段：①新太古至古、中元古代金初始矿源层形成阶段；②中元古代末期区域变质─混合岩化金再富集阶段和③燕山期构造─流体─金成矿作用阶段。 |

| Abstract: | The Mouping－ Rushan gold ore belt lies in the activated region on the eastern margin of the North China Craton.The Jingshan and Jiaodong Groups metamorphic green formation is the source bed of the gold mineralization in this region.The main controlling structures are the NNE,and NE － trending faults.Gold ore main type is auriferous quartz vein type.Ore－ forming fluid rooted in the deep crust mixed with meteoric water.The research for metallogenic evolution mechanism in the region indicates that gold ore formation has undergone three stages:① gold elementary source bed formation stage from the Neo－ Archean to the Paleo－ Proterozoic and Meso－ Proterozoic,② regional metamorphism－ migmatization gold reenrichment stage at the late Meso－ Proterozoic,③ structure－ fluid－ gold mineralization stage at the Yanshan Period. |
