英文摘要	We report the occurrence of coexisting garnet + corundum in spinel- and corundum-bearing, gamet-sillimanite-biotite-graphite gneiss (pelitic granulites) from the Highland Complex (HC), Sri Lanka. In the investigated pelitic granulites, two domains such as quartz-saturated and quartz-undersaturated are distinguishable. The quartz-saturated domains consist of porphyroblastic garnet, quartz, plagioclase, alkali-feldspar and biotite flakes rimming garnet The quartz-undersaturated domains are constituted of two generations of garnet (Grt(1) and Grt(2)), sillimanite, plagioclase, alkali-feldspar, corundum, spinet and biotite. Grt(1) encloses rare Ti-rich biotite and numerous rutile needles and apatite rods. Grt(2) contains rare sillimanite and/or spinel inclusions. Corundum occurs in mutual contact with Grt(2), partially embedded at the rim or as an inclusions in Grt(2).
