PETROLOGY AND FLUID INCLUSION STUDIES OF CORDIERITE BEARING GNEISSES: A CASE STUDY FROM THE KERALA KHONDALITE BELT, INDIA

The petrological, geochemical and fluid inclusion characters of Cordierite bearing gneisses of Kulappara are reported in this study. The common mineral assemblages of the quarry were identified as Garnet + Sillimanite + Cordierite + K-feldspar + Biotite + Quartz + Plagioclase + Rutile with accessory mineral such as Zircon and Monazite.The symplectite and granoblastic textures were obtained from the samples which revealed that the prograde and retrograde metamorphic mineral reaction might have prevailed during partial melting. The parentage material of the Kulappara Khondalitequarry might have been derived from Pelitic rocks. The presence of CO2 rich fluids were observed entirely in the quarry
