High-grade metamorphic rocks widely spread in the Mt. Riiser-Larsen, Napier Complex, East Antarctica, which experienced 1000-1100 ℃, 0.6-0.9 GPa peak metamorphism. We focused on sulfide minerals in these rocks. We will present the occurrence of sulfide minerals and sulfur isotope ratios and discussion about sulfur movement.
