Integrated metamorphic and geochronological data place new constraints on the metamorphic evolution of a Neoproterozoic orogen in east Antarctica. Granulite-facies rocks from a 150km stretch of the Kemp Land coast reflect peak conditions involving T ≈ 870-990°C at P ≈ 74-10 kbar, with pressure incre...
