在分析烟台北部芝罘群主要变质岩类的变质矿物共生组合、变质相系及构造岩等特征的基础上 ,对该群变形、变质作用及演化特征进行了探讨。认为该区芝罘群曾经历 1期韧性变形作用和 4期变质作用 (古元古代高角闪岩相、中元古代早期低角闪岩相、中元古代晚期高绿片岩相及新元古代低绿片岩相变质作用 )。 On the basis of analyzing the characteristics of the metamorphic minerals, metamorphic facies and tectonic rocks of the major metamorphic rocks of the Zhifu Group in northern Yantai, the deformation, metamorphism and evolution characteristics of the metamorphic rocks are discussed. It is believed that the Zhizu group in this area experienced one-stage ductile deformation and four-stage metamorphism (Paleoproterozoic amphibolite facies, Proterozoic Early Lower Amphibolite facies, late Proterozoic high greenschist facies and Neoproterozoic low green Schist facies metamorphism).
