The Bunger Hills area of the East Antarctic Shield consists of granulite-facies felsic orthogneiss, with subordinate paragneiss and mafic granulite. The igneous precursors of granodioritic orthogneiss were emplaced 1500-1700 Ma ago, and late Archaean (2640 Ma) tonalitic orthogneiss occurs in the nearby Obruchev Hills. Peakmetamorphism (MI) (at about 750-800°C and 5-6kb) occurred 1190 2 15 Ma ago (U-Pb zircon age), and was accompanied by the first of three ductile deformations (DJ Emplacement ofdoi:10.1017/s0954102093000112 fatcat:hs6uigqbxzacto73ql7dqfvhum
