Abstract

East Andaman Basin (EAB) is a north-south oriented elongated basin located in the Andaman Sea. This basin is bounded by the Mount Sewell Rise at its East and the Mergui Ridge at the West. Recent studies by Eni operated consortium reveal that the basin originated during Paleogene in response to the back-arc related extension (rifting) and is time & genesis-equivalent to the other rift basins present on the western margin of Sundaland (namely North Sumatra, Mergui, Moattama Basins). East Andaman basin has undergone series of complex events and is currently in ultra-deepwater setting (avg. water depth 2000m and more).
