Abstract

In this short paper, we outline the potential links between India and the East Antarctica region from Enderby Land to Princess Elizabeth Land using the Mesozoic East Gondwana configuration as a starting point. Palaeomagnetic data indicate that East Gondwana did not exist prior to the Ediacaran–Cambrian. Early Neoproterozoic (1050–950 Ma) deformation in East Antarctica and along the Eastern Ghats Province in India marks the initial contact between the two regions. Volcanism in the Kerguelen hotspot led to final break-up of India and East Antarctica in the Cretaceous. Although connections between the Archaean and Proterozoic provinces of India and East Antarctica have been proposed, the current record of large igneous provinces (or dyke swarms), palaeomagnetic data and geochronology do not show a consistently good match between the two regions.
