文摘
- •
HP granulite metamorphism constrained around or even earlier than 1.95 Ga with retrograde age of 1.85 Ga.
- •
Mafic granulite and meta-sediments melted for granitoid at ∼1.95 Ga.
- •
Estimated four stages of P-T paths with peak conditions of 880–890 °C and >13 kbar.
- •
Mafic granulite and meta-sediments underwent similar metamorphic history after 2.0 Ga.
