A voyage from Chennai across the Bay of Bengal takes one eventually to the Andaman Islands. But it was a different situation in the geologic past during the Late Cretaceous (80-68 m.y. BP). There was a chain of islands somewhere midway which currently lies as the buried 85E Ridge beneath enormously thick sediments discharged by the Ganges and Brahmaputra river systems.

Abstract


A voyage from Chennai across the Bay of Bengal takes one eventually to the Andaman Islands. But it was a different situation in the geologic past during the Late Cretaceous (80-68 m.y. BP). There was a chain of islands somewhere midway which currently lies as the buried 85E Ridge beneath enormously thick sediments discharged by the Ganges and Brahmaputra river systems.
