Abstract: The Earth's continents can extend deep into the mantle, and these continental roots are thought to be cooler than the surrounding mantle material. So they could lower mantle temperature and even induce downwelling. But a seismological study across eastern North America finds that, there at least, these features of a continental 'coldfinger' are absent.
