| 摘 要： | 利用电子探针等方法研究了青岛榴辉岩相变质古洋壳(蛇纹岩、C类榴辉岩和基性糜棱岩)的岩石学和地球化学特征。确定了它们为华南陆块与华北陆块拼合前的古洋壳,当其俯冲于华北陆块之下时在深部发生碱质交代及低温高压变质作用(C类榴辉岩相)。

| Abstract: | The petrological and geochemical characteristics of the eclogite face metamorphic palaeo-ocean crust ( serpentite,type C eclogite and basic mylonite) have been studied with electron-probe and other methods.It has been determined that it was the palaeo-ocean crust before the closure of the Southern China Plate and the Northern China Plate,and when it was driven beneath the Northern China Plate alkalireplacement and low temperature and high-pressure metamorphism (type C eclogite face) took place. |
