High-pressure experiments were carried out at pressures 7–15 kbar and temperatures 850–1150 °C using the piston cylinder apparatus. Experimental data give constraints on the
path of sillimanite-cordierite-sapphirine granulites from Rundvågshetta, Lützow-Holm Complex, East Antarctica. Combining the previous temperature estimates and the present data, we can infer that the Rundvågshetta granulites experienced the peak metamorphism at 925–1039 °C and 11.5–15 kbar within the stability field of garnet, orthopyroxene, sapphirine and sillimanite. Subsequent retrograde metamorphism took place at 824–1010 °C and 6.5–10.8 kbar accompanied by breakdown of garnet and consumption of orthopyroxene and sillimanite within the stability field of orthopyroxene, sapphirine, spinel and cordierite.
