A joint geophysical-geochemical deep-mantle zoning map beneath East Africa and the Indian Ocean.

Geochemical signatures of hotspot lavas suggest that their mantle sources are compositionally distinct, but their source locations remain elusive.

Geochemical signatures of hotspot lavas suggest that their mantle sources are compositionally distinct, but their source locations remain elusive. Mapping hotspots to their deep origins is complicated by the presence of interconnected, low-seismic velocity networks in the…
