Mineralogically these rocks are characterized by the presence of quartz , albite ,
oligoclase ( An 2 An , c ) , microcline , perthite , biotite , sericite , chlorite ,
muscovite , andalusite , staurolite , zircon , tourmaline , sphene , epidote and
opaques .

In the present study an attempt has been made to study the normal and reverse
zoning in garnet belonging to Zones B , C and D. The garnet in Zone B is mainly
almandine and is characterized by decreasing Mn content from its core to rim .
