Summary

In the last 30 years, geologists have made much progress on understanding slabs, lithosphere, and mid-ocean ridges but mantle plumes remain enigmatic. In their Perspective, Montagner and Ritsema chart recent progress, largely based on seismic anisotropy, toward understanding how such plumes interact with mid-ocean ridges. Existing data are insufficient, however, to determine whether mantle plumes act independently from plate tectonics. The authors call for ocean bottom seismic stations to settle this question.
