Abstract
Orthopyroxene-bearing rocks viz., quartz-norite, cordierite-biotite-hypersthene granulite, leptynite and hypersthene-biotite quartzite containing minerals like hypersthene (aluminous), diopside, brown hornblende, biotite, garnet, cordierite, plagioclase and quartz, occur constituting an integral part of the high-grade metapelites of the area. The field and petrological observations suggest that these orthopyroxene-bearing rocks are variants of the metapelites, derived by the metamorphism of appropriate sediments and have no connection with the associated charnockites of the area.Downloads
