Structure of the cretaceous Kerguelen volcanic province (southern Indian Ocean) from wide-angle seismic data

Travel time inversion and amplitude modelling of OBS wide-range seismic data recorded in the Enderby Basin, west of the Kerguelen Plateau, show a 10 to 13 km thick crust characteristic of oceanic crust emplaced near a hotspot (velocity reaches 7.4 km/s at the bottom of the crust). From this study we...
