Large igneous provinces (LIPs) are constructed when copious amounts of mantle-derived magma enter the Earths crust in localized regions. Although the Kerguelen Plateau and Broken Ridge are now submarine, they formed as a contiguous, largely subaerial LIP during Cretaceous time in the eastern Indian Ocean. Subsequently, they were separated by sea-floor spreading beginning in Middle Eocene time along the Southeast Indian Ridge (SEIR; Fig. 1). The Kerguelen Archipelago is a Cenozoic feature constructed on the Northern Kerguelen Plateau (NKP; Fig. 1). Together with the
8238 Ma hotspot track formed by the Ninetyeast Ridge, the Kerguelen Plateau, Broken Ridge and Kerguelen Archipelago represent
119 Myr of volcanism that has been attributed to the Kerguelen mantle plume. Although the igneous basement of the Kerguelen Plateau had been sampled at Sites 738, 747, 749 and 750 (Fig. 1) by Ocean Drilling Program (ODP) Legs 119 and 120, Leg 183 was
