Indian Ocean floor deformation induced by the Reunion plume rather than the Tibetan Plateau
The central Indian Ocean is considered the archetypal diffuse oceanic plate boundary. Data from seismic stratigraphy and deep-sea drilling indicate that the contractional deformation of the Indian Ocean lithosphere commenced at 15.4-13.9 Ma, but experienced a sharp increase at 8-7.5 Ma. This has been maintained through to the present day, with over 80% of the shortening accrued over the past 8 Myr. Here we build on previous efforts to refine the form, timing and magnitude of the regional...[Show more]
