Abstract:
Grandidierite, kornerupine, and tourmaline occur in high-grade pelitic gneisses from the Larsemann Hills, East Antarctica. The three minerals contact to each other and show a special order: Trn1→Gdd→Trn2→Krn→Trn3, suggesting the occurrence of the assemblage is controlled by the temporal changes of the chemical potentials of B2O3 and H2O. The discovery of the assemblage is a good constraint on the seting and composition feature of metamorphism in the area.
Key words: grandidierite, kornerupine, tourmaline, boron, evolution
