摘要
根据鲁东榴辉岩的产状、与围岩的接触关系、多期变质变形特征及同位素测试资料 ,对其进行了构造年代学总结 ,认为鲁东榴辉岩形成于 6 13～ 90 0 Ma,于 2 0 7～ 32 9Ma发生强烈抬升作用。
This paper reviews the research progress of tectonic chronology of eclogite in Eastern Shandong.The eclogite is an inclusion of granit gneiss, which is intruded by Upper Proterozoic granite geniss and Mesozoic magmatite and superimposed polygenetic metamorphism and deformation.Based on the introduction of attitude,contact relation,metamorphism deformation and isotopic age,the authors suggest that the eclogite facies appeared during 613—900 Ma, with an uplift aged 207—329 Ma.
