They were exhumed upto the surface together with the Dabie complex after they were metamorphosed into eclogite at depth.During exhumation eclogite underwent different degrees of retrometamorphism.

在深部变质形成榴辉后又随大别起被抬升到地表，在抬升过程中经了不同程度的退变质作用。

The former three stages reflect the major process of eclogite facies metamorphism and the latest stages the light overprinting of greenschist facies retrometamorphism at the shallow level of crust.

前三个映了榴辉相变质作用的主要过程。后，映了榴辉在地壳浅部层次绿片相环境下遭受轻微的叠加改造。
