Abstract

The Raman spectral intensity of CO2 in the cordierite channel varies considerably depending on the crystal orientation of cordierite, because it is orientated linearly along the a-axis in cordierite channel. From the Raman intensity ratio of cordierite peaks obtained from euhedral crystals of cordierite, it is possible to identify crystal orientation of cordierite. In order to check the reliability of this method and its application for the determination of CO2 contents in cordierite channel, we analyzed and compared using cordierite from gneisses in the KKB, southern India.
