Two decades of Indian research on Ninetyeast Ridge reveal how seafloor spreading and mantle plume activities have shaped the eastern Indian Ocean.
Abstract
It is widely accepted that the Ninetyeast Ridge ridge is a product of volcanic trace of the Kerguelen mantle plume (hot spot) on the northward-drifting Indian plate between ~85 and 42 Ma. Studies carried out from the early 1990s to 2013 have brought out greater details on spreading centre – hot spot interactions, mid-ocean ridge migrations, ridge jumps, evolution of triple diffuse-plate boundary between the subplates, etc. Major inferences drawn from the research work carried out in last two decades has been briefed here.
