Article Abstract

Hotspots tracks—chains of volcanic edifices arising from deep mantle upwellings—were once thought to solely record plate motion. Results of ocean drilling expeditions have led to a transformative change: it is now recognized that these tracks can also reflect the motion of hotspots in Earth’s mantle. When hotspots move, their paths can provide insight into the nature of the mantle and the history of convection.
