The Grove Mountains are an inland continuation of the Late Neoproterozoic/Cambrian Prydz Belt of East Antarctica. In this paper we report high-pressure (HP) mafic granulites that occur in glacial moraines from this area. Petrographical textures, mineral compositions and P-T pseudosection calculation...
