Peer Reviewed Journal 26 Impact Factor 5.20 (EduIndex) www.aarhat.com Vol VI Issues NO V ABSTRACT 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 CO 2 rich fluids were observed entirely in the quarry.

INTRODUCTION The linear strip of land, forming the southern tip of the peninsular Achaean gneiss – granulite terrain (Radhakrishna, 1989), constitute one of the oldest regions in the Indian shield and it was undergone multi tectogenesis (Rao, 1978). Kerala state covers an area of 38,864 sq Km and is located in the south western part of the Indian Peninsular shield. Geologically Kerala is composed of Precambrian crystallines, acid to ultra-basic PETROLOGY AND FLUID INCLUSION STUDIES OF CORDIERITE BEARING GNEISSES: A CASE STUDY FROM THE KERALA KHONDALITE BELT, INDIA Babu Nallusamy 1 , Sharath Raj B 1 , Mohammed-Aslam M A 1 , Akhil Unnikrishnan 1 , Syed Hamim Jeelani 1 , and Sundararajan M 2* 1Department of Geology, Central University of Karnataka, Kadaganchi, Aland Road, Kalaburagi-565367, Karnataka 2 Minerals and Metallic Materials, National Institute for Interdisciplinary Science and Technology, Trivandrum *Corresponding author: rajanmsundar77@yahoo.com
