5E3-92FGranulite, Quartz SiO2 , K Feldspar, Albite Na(AlSi3O8) , Almandine Fe2+3Al2(SiO4)3 , Rutile TiO2 , Graphite C
Field of View: 14.5 mm
Close-up view of a typical granulite from this quarry: A quartz-feldspar matrix hosts pale pink grains of Mg-rich almandine, brown flakes of a Fe2+-, Ti- and F-bearing phlogopite, tiny rutile prisms and grains (dark brown; always with trace impurities of Zr - high-pressure indicator! - Si, Nb and Al), rare tiny graphite flakes and very rare pale grey-bluish kyanite (not visible here).
