Geochronology of the Polycyclic Granulite Terrain of The Eastern Ghats Mobile Belt: An Overview

Abstract

The Eastern Ghats Mobile Belt is dominantly characterized by the granulite facies of high-grade metamorphic rocks lying along the eastern coast of the Indian subcontinent. These polycyclic high-grade rocks include several blocks bounded by faults in the northern margin and a prominent shear zone towards the western margin. Recent imputes made in the EGMB proclaim various smaller domains characterized by their distinct tectono-metamorphic evolutions. However, the correlation made between the various metamorphic and tectonic events with respect to their geochronologic ages still lack solid results. As such, we contemplate to impart an overview based on the observations made from the available isotopic data of the Eastern Ghats Mobile Belt.
