| 摘 要： | 辽河群变质岩主要由片岩、大理岩、变粒岩、浅粒岩和板岩等十大岩类组成。主要岩石稀土元素组成具有变沉积岩的稀土分配特征。片岩和大理岩、变粒岩和浅粒岩的原岩主体为沉积岩,个别为火山岩,它们主要来源于大陆上部地壳;部分属上地幔或接近于大陆溢流玄武岩的物质经部分熔融的产物。

| Abstract: | Metamorphic rocks from Liaohe Group are consisted of ten kinds of rocks, such as schist,marble,granulite,leucogranulite,slate,and so on,which REEs have the characteristics of rare earth distribution of recta-sedimentary. The protoliths of schist and marble, granulite and leucogranulite principally are sedimentary rocks,rarely volcanic rocks, which mainly originated from upper crust of continental, partly from upper mantle or near the partly melted products of continental flood basalt. |
