Photomicrographs of type 1 mafic granulites. (a) Equilibrium assemblage of garnet + clinopyroxene + amphibole + plagioclase + ilmenite (sample TKL18-4). (b) Clinopyroxene, amphibole, plagioclase, quartz, and ilmenite occurring as inclusions in garnet grains (sample TKL18-4). (c) Orthopyroxene occurring as coronae around clinopyroxene (sample TKL18-4). (d) Mineral assemblage of garnet + clinopyroxene + orthopyroxene + amphibole + plagioclase + ilmenite (sample TKL02-2). Orthopyroxene is in all cases adjacent to clinopyroxene. Plagioclase occurs as coarse grains measuring 0.5–2.5 mm across (Pl-1) and fine grains of <0.5 mm (Pl-2). (e) Inclusions of clinopyroxene, amphibole, plagioclase, quartz, and ilmenite in garnet grains. Orthopyroxene exsolution lamellae in clinopyroxene (sample TKL02-2). Mineral abbreviations in all figures are after Whitney & Evans (2010).
