绿帘角闪岩相

研究发现，尽管它们有着不同的峰变质条件，但都经历了相同的绿帘角闪岩相前进变质，具有相近的峰变质年龄和相似的退变质轨迹。

The study shows that they have all experienced the same epidote amphibolite facies metamorphism although their peak metamorphic conditions are different . Their peak metamorphic ages are very close and they have similar retrogressive metamorphism paths .

三个变质作用阶段的特征是：前榴辉相阶段为中压相系绿帘角闪岩相；

The characteristics of three metamorphic stages are as follows : before the eclogite-facies stage which is middle-pressure epidote amphibolite facies ;

在含蓝闪石岩分布区，岩石的变质相有葡萄石-绿纤石相、蓝闪石绿片岩相、绿帘石-角闪岩相、铁铝榴石角闪岩相等，未发现高压低温矿物组合。

In the glaucophane-bearing rocks there distributed some sections , in which the metamorphic facies of the rocks are mainly of prehnite-pumpellyite facies , glaucophane-greenschist facies , and epidote ( almandine ) - amphibolite facies etc , but the high temperature-low pressure mineral associations are not discovered .
