Abstract

The tonalite-granodiorite suite adjoining the Ramagiri schist belt carry enclaves of amphibolites. The chemistry of this suite suggests that it is magmatic, metaluminous and calc-alkaline, and it is grouped under 'mixed' origin. Various lines of evidences show that this tonalite-granodiorite suite is a partial melt of the amphibolite of the Ramagiri schist belt which was recyled at the crust-mantle levels.
