The major rock unit is a leptynitic gneiss (quartz-plagioclase-garnet-K-feldspar) that is migmatitic in nature In places, this Leptynitic gneiss contains fliation-parallel elongated enclaves of gneissic aluminous granulite. The gneissic foliations in both the aluminous granulite and the host migmatitic gneiss are parallel. Layer parallel bands f charnockitic gneiss (quartz-K-feldspar-orthopyroxene-plagioclase-garnet) are present in the host migmatite (K. Das, et al (2006)).
