麻粒岩和榴辉岩中退变质阶段的角闪石主要形成于中压相系角闪岩相的温压条件。
The amphiboles of retrogressive metamorphic stages in the granulite and eclogite were mainly formed under the condition of amphibolite facies of medium pressure facies series.
变质相由基底岩系的低角闪岩相—高绿片岩相逐渐过渡为上覆盖层的低绿片岩相。
The metamorphic facies gradually change from low amphibolite—high green-schist facies of the basement to low green-schist of the cover.
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;
