【Abstract】 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.更多还原
