<!--!introduction!--> Understanding of the evolutionary geodynamics of the Eastern Ghats Mobile Belt (EGMB), is crucial to reconstruction of the Rodinia and Gondwana supercontinents. However limited aspects of its structure and evolutional origin are known. Based on lithological assemblage and geochronological data, EGMB is divided into multiple heterogeneously deformed terranes. Recent seismological studies across the EGMB-Archaean craton boundary adds new perspective regarding the deformation of the region and its correlation with East-Antarctica. Integrated studies reveal heterogeneous structure across the craton and mobile-belt characterised by 32-37km, ~42km and 110-160km, 80-120km thick crust and lithosphere respectively, suggesting collisional thrusting of EGMB against the Archean Cratons that explains the abrupt changes in crustal thickness across the craton-mobile belt. The influence of mantle-plumes, owing to the trajectory of the Indian subcontinent across the Kerguelen/Crozet hotspots, ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
