Geological evolution of the northern and northwestern Eastern Ghats Belt, India from metamorphic, structural and geochronological records: An appraisal

Abstract

The Eastern Ghats Belt of India remains a focus of intense research by the international geoscience community to understand the Proterozoic crustal evolution. This terrane experienced anomalous thermal perturbation at least two times in Earth’s history and those are linked with the assembly of two Proterozoic supercontinents. It is clearly demonstrated from existing rock records that the terrane experienced multiple events of metamorphism, magmatism, and deformation characterizing separate crustal provinces. Despite this, a clear gap in understanding the evolution of this terrane particularly on its northern and northwestern part still exists. The present review presents an update of these issues which can be taken into consideration for future research of this complex terrane.
