VOLCANISM in active continental rift zones1,2or on rifted continental margins3is frequently associated with unusually high lower-crustal seismic velocities, indicating the presence of large igneous intrusions at the base of the crust. The only comprehensive investigation of crustal underplating at an oceanic hotspot, beneath Hawaii4–6, has yielded controversial results7. Here we report the results of seismic refraction experiments across the Marquesas Islands hotspot trace, which show that the… CONTINUE READING
