Metamorphic minerals all display retrograde textures and compositions. Retrograded eclogite record eclogite facies P-T condition of 500–560 °C, 23–24 kbar. Mafic granulite record granulite facies P-T condition of 860–890 °C, 5–6 kbar. Metamorphism occurred at 245–251 Ma and protolith age of granulite is 997 Ma.
