The intrusion of pink granite (2380·2000 m.y.) and its consanguineous pegmatites in and around Manalur. possibly resulted in the migmatization of the two· pyroxene granulites.lt is presumed that the reactive fluids had moved along the major shear planes of Eastern Ghat belt and Caused the formation of intermediate and acidic rocks. Petrochemical study of the different rock types also confirms this view.
