JR Expedition 324: Shatsky Rise
One of the most fundamental questions of modern geodynamics is the process of mantle convection and its impact on Earth’s surface through volcanism. The greatest source of nonocean-ridge volcanism appears to be massive eruptions that formed oceanic plateaus. A widely accepted hypothesis for this kind of volcanism is that it results from the head of a starting plume, which rises from the deep mantle, spreads out beneath the lithosphere, and melts in a massive outpouring of volcanic activity. Despite the wide acceptance of this hypothesis, a convincing case for a plume head origin has never been made for any oceanic plateau.
