Abstract

Tectonics controlled evolution of deep crustal exposures have recently attracted much attention. The southern part of Peninsular India, consisting of highgrade metamorphic rocks, sandwiched between converging rifted margins, shows characteristically different geophysical signatures as compared to other geologically similar provinces. Based on geophysical anomalies and the tectonic framework of the region it is proposed that the subsurface structural configuration beneath the granulite terrain of South India has been perturbed by Meso-Cenozoic rifting at the continental margins and consequent crust-mantle dynamics.

Keywords
