… This paper reports the first evidence of ultrahigh-temperature (UHT) metamorphism from the Sor Rondane Mountains, eastern Dronning Maud Land, East Antarctica, which is evident as orthopyroxene + spinel symplectite in an amphibolitized mafic granulite. … The obtained pressure-temperature (P-T) conditions and P-T path are different from the UHT metamorphism from the Schirmacher Hills, central Dronning Maud Land, which is considered to have occurred in a back-arc tectonic setting. …
