P–T path deduced for mafic granulites from the Archean crustal domain in the Rauer Group. The P–T paths for UHT granulites from the Rauer Group are labeled as follows: (1) Mg–Al-rich metapelite from Mather Peninsula (Harley, 1998b); (2) Mg–Al-rich metapelite and mafic granulite from Mather Peninsula (Tong & Wilson, 2006); (3) Mg–Al-rich metapelite from Short Point and Fe-rich metapelite from Filla Island (Kelsey et al., 2003a, 2007); (4) Mg–Al-rich metapelite from Mather Peninsula (Harley, 2016); (5) Garnet–orthopyroxene granulite from Lunnyj Island (Clark et al., 2019). The grey districts represent the P–T conditions of M₀–M₃ generations of mineral assemblages constrained by conventional thermobarometry. The dotted blue curves represent quartz-out in mafic granulites, as constrained by pseudosection modeling (Figs 7a and 8a). Abbreviations: NG = ‘normal’ granulite; UHTG = ultrahigh-temperature granulite; E–HPG = eclogite–high-pressure granulite. The areas of NG, UHTG, and E–HPG are from Brown (2007).
