The present communication aims at an assessment of the current status on petrological evolution of the Eastern Ghats Belt in the context of its correlation with three supercontinents, namely Columbia, Rodinia and East Gondwana. Despite intensive research by different groups over the last three decades, various issues remain unresolved. Some major outstanding issues include, the nature of the basement for the Eastern Ghats rocks, isotopic and / or lithotectonic subdivisions of the belt, nature of the retrograde path of UHT metamorphism and timing of juxtaposition of the mobile belt with the adjacent cratons.
