Abstract
If Dabie Shan UHP metamorphism is of the generally accepted Triassic age (210-240 Ma), the apparent age of a phengite sample in equilibrium with the garnet can be explained by the presence of an extraneous 40Ar∗ component with mean 40Ar/36Ar value of ∼5000. This value is similar to the composition of extraneous 40Ar∗ in other eclogite facies terrane.
