"Christmas Point" pegmatite, Khmara Bay, Casey Bay, Napier Complex, Enderby Land, Eastern Antarctica, Antarctica

Description: Khmaralite forms a foliated aggregate nearly 3 cm across of parallel tablets. The tablets are flattened parallel to {010} and a few grains show these faces. Individual tablets range from 1 to 7 mm across and from 0.5 to 4 mm thick as seen in thin section. Khmaralite is most closely associated with sillimanite, surinamite, musgravite, garnet, and biotite,. The textures of the aggregates, particularly the relatively fine grain size (few mm to nearly 3 cm) and preferred orientation, suggest a metamorphic origin. Grew proposed granulite-facies conditions of ≥ 820 °C, ≥ 10 kbar after intrusion. Khmaralite and associated minerals are inferred to have formed by metamorphism of pre-existing pegmatitic Be phases.
