Abstract
Laser Raman micro-spectroscopic studies on graphite flakes in pyrite-bearing graphite-mica schist indicate the presence of graphites from chlorite-biotite to staurolite-kyanite grades. Although such a wide variation implies graphite formation both in the prograde and retrograde sequences, consideration of some pertinent spectral parameters such as the average O-peak width and the asymmetric nature of the S-peaks indicates preservation of higher grade graphite crystallinity.
