摘　　要：东腰庄绿岩带型金矿床赋存于五台山绿岩带之中,赋矿地层为新太古界五台群鸿门岩组绿片岩,具有明显的层控性。该矿床由Ⅰ、Ⅱ、Ⅲ号3个矿体构成,矿体呈似层状和脉状,走向NE。容矿岩石为强烈黄铁矿化、硅化和碳酸盐化的绢云钠长片岩、绢云石英片岩、绢云钠长绿泥片岩和变辉绿岩脉。围岩蚀变发育,主要为硅化、绢云母化、绿泥石化、碳酸盐化和黄铁矿化,由内向外呈现出分带性。矿床具有明显的地质、地球物理及地球化学找矿标志。Dongyaozhuang greenstone belt gold deposit occur in the greenstone belt of Wutai mountain,the ore iormation is new Archean Wutai group Hongmen rock group green schist,it has obvious layer controlling.The deposit is formed by three orebodies, Ⅰ , Ⅱ, Ⅲ ,the shape of orebody is bedded and vein,north-east trending.The bearing-rock is albite sericite schists,quartz schist, chlorite albite and diabase dikes,which are strongly pyritization,silicification and carbonate.The wall-rock alteration develop,the alteration is mainly quzatz,sericite,ehlorite carbonate and pyrite,from inside to outside,it shows zonation.The deposit has obvious geological,geophysical and geochemical prospecting criteria.
