Mantle plumes and their role in Earth processes
The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

Continent-sized anomalous zones with low seismic velocity at the base of Earth's mantle
Seismic images of Earth's interior reveal two massive anomalous zones at the base of the
mantle, above the core, where seismic waves travel slowly. The mantle materials that …
