| Summary: | The Kerguelen hotspot became active at least 115 Ma ago, after the break-up of Gondwanaland. The Kerguelen mantle plume is responsible for extensive volcanism in the Indian Ocean basin, including the Ninetyeast Ridge, Broken Ridge and the Kerguelen Plateau, in the southern I dian Ocean (see references in, and Hassler and Shimizu, 1998 for a synopsis). The southern Kerguelen Plateau is one of the earliest known products of the Kerguelen plume (115 Ma), and the Ninetyeast Ridge tracks the northward migration of India, from>83 Ma to 43 Ma. Broken Ridge and its conjugate, the northern Kerguelen |
