Figure F1. Map of the eastern Indian Ocean showing major physiographic features and proposed Leg 183 sites where igneous basement was recovered from the Ninetyeast Ridge, Broken Ridge, and Kerguelen Plateau by Deep Sea Drilling Project and ODP drilling (circles) and dredging (squares). Rajmahal Traps, lamprophyres, and Bunbury Basalt (BB) are continental volcanics that have been postulated to be related to the Kerguelen plume. Star = a proposed location (Skiff Bank) for the Kerguelen hotspot (Coffin, Frey, Wallace, et al., 2000).
