二者主要为副变质岩石,米兰岩群和卡羌岩群、阿拉玛斯岩群变质较深为角闪岩相,普遍弱混合岩化,它们具有非常相似的地球化学特征,稀土元素总量及其它特点一致或相近。 - The research for metallogenic evolution mechanism in the region indicates that gold ore formation has undergone three stages : gold elementary source bed formation stage from the neo - archean to the paleo - proterozoic and meso - proterozoic , regional metamorphism - migmatization gold reenrichment stage at the late meso - proterozoic , structure - fluid - gold mineralization stage at the yanshan period
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:新太古至古、中元古代金初始矿源层形成阶段;中元古代末期区域变质混合岩化金再富集阶段和燕山期构造流体金成矿作用阶段。
