Abstract: This communication discusses the metamorphism of low pressure granulites in the Sukma supracrustal suite near Nagaras in the southern Bastar craton. The area shows occurrence of Mg-Al rocks,of both amphibolite and granulite facies. Amphibolite facies Mg-Al schist usually contains cordierite and, a low-Ca amphibole, which is commonly cummingtonite and rarely gedrite. Low-Ca amphibole and sillimanite are never found together in the same rock. Mg-Al granulite is characterised by the presence of orthopyroxene in lieu of low-Ca amphibole. Most of the Mg-Al rocks are silica saturated.
