a P–T pseudosections for the mafic granulite H2608 calculated in NCKFMASTHO system. The used bulk compositions (wt%) are SiO2 (44.81), TiO2 (1.62), Al2O3 (14.39), FeO (12.37), MgO (7.30), CaO (12.00), Na2O (1.34), K2O (0.77), and O2 (0.51). The peak and retrograde assemblages are shown by black and white bold letters. b Compositional isopleths for amphibole. The amphibole stability is contoured in terms of XMg and Si content. Solid ellipse indicates P–T conditions at which the observed amphibole core composition is reproduced. c Compositional isopleths of Xgrs and XMg for garnet. Dashed ellipse indicates P–T conditions inferred from the observed compositions of garnet. Na-Am sodic amphibole
