There are two competing hypotheses for the origin of oceanic plateaus: plume versus plate. Thermodynamic modelling of magmatism at Shatsky Rise, in the Pacific Ocean, now suggests that neither mechanism is adequate on its own and in fact plume–ridge interaction is required to explain the formation of this ocean plateau.
