THERMAL convection in the mantle is the most important dynamic process in the Earth's interior. Two quite different approaches are currently used to provide and analyse information regarding lateral temperature variations in the upper mantle. On the one hand, the major-element chemistry of basalts erupted at mid-ocean ridges is directly influenced by the temperature of the mantle beneath1–5; on the other, seismic velocity studies6–17 can be used to map lateral temperature variations on a global… CONTINUE READING
