| 摘 要： | 用电子探针分析了山东荣成榴辉岩和石榴石橄榄岩中的石榴石和单斜辉石的化学组成。利用石榴石成分—成因判别图解并结合矿物地质温度计估算结果,判断荣成榴辉岩和石榴石橄榄岩为地幔来源,部分榴辉岩经历了后期壳内角闪岩相退变质作用。最后讨论了它们的成因意义和动力学演化。

| Abstract: | The composition of garnet and dinopyroxcnc from cclogite and/or garnet peridotite in Rongcheng area have been analysed bv clcctronprobc With the distinguish diagram of component-genesis for eclogite and garnet peridotite and combined with the equilibrium temperature and pressure estimated by geothermometcr and geobarometer,it was determined that the cc-logitc and garnet peridotite came from the mantle,and a part of the eclogite underwent retro-metamorphism of the amphibole fate in the crust Finally,the genesis significance and dynamics evolution of the cclogite and garnet peridotite arc discussed |
