Whole rock and mineral analysis, and melt compositions of granulites from Grove Mountain, Antarctica
Abstract:
Table S1 Representative chemical compositions of minerals in the UHT granulites from the Grove Mountains, East Antarctica.
Table S2 Effective whole-rock compositions of UHT granulites from the Grove Mountains used in phase equilibria modeling (mol.%).
Table S3 LA-ICP-MS U-Pb isotope and trace element data for zircons of UHT granulites from the Grove Mountains.
Table S4 LA-ICP-MS U-Pb isotope and trace element data for monazites of UHT granulites from the Grove Mountains.
Table S5 LA-ICP-MS in-situ biotite Rb-Sr analysis results for the UHT samples and standard sample ZBH-25.
Figure S1. Melt and garnet content variation diagrams for (a-b) MSW59J-3A2, (c-d) MSW24-1A, and (e-f) MSW22-3A.
Figure S2. T–Xmelt pseudosections for (a) MSW59J-3A2, (b) MSW24-1A, and (c) MSW22-3A. Melt compositions were calculated using the equilibrium conditions of each sample at 1000°C and 7 kbar. Residue compositions were derived by subtracting 35% peak-stage melt compositions from the effective bulk rock compositions for maintaining the H2O content > 0.
Figure S3. Representative zircon cathodoluminescence images for (a) MSW59J-3A2, (b) MSW24-1A, and (c) MSW22-3A. Yellow arrows indicate evidence of melt-mediated coupled dissolution–precipitation replacement reactions.
