| 摘 要： | 赞皇变质杂岩区位于阜平杂岩南部,地处华北克拉通中部造山带的中段,和中部带北段杂岩一样,是洞悉华北克拉通前寒武纪基底构造演化历史的一个重要窗口.研究区变基性岩可分为斜长角闪岩和角闪斜长片麻岩两种,二者均以似层状方式产于黑云斜长片麻岩或长英质片麻岩中,斜长角闪岩亦可呈透镜状,二者后期与围岩一起共同经历了高角闪岩相变质作用....

| Abstract: | The Zanhuang metamorphic complex is significant for understanding the Precambrian tectonics and evolution of the North China Craton.Metabasic rocks composed of amphibolite and amphibole-bearing plagioclase gneiss as thin layers or lenses are widely distributed within felsic gneisses and biotite-plagioclase gneisses.These metabasic rocks together with country rocks underwent high-amphibolite facies metamorphism,and abundant metamorphic zircons were formed during this thermal event.SIMS U-Pb chronological ana... |
