Low seismic velocity anomalies reveal a complex scenario of plume upwellings from a deep thermo-chemical anomaly (superplume) in the mantle below the East African Rift, however, geophysical observations alone are insufficient to identify the extent of plume influence on the magmatism along the rift. Here, the authors use Sr-Nd-Pb isotope data to show that superplume mantle underlies the entire rift system, from the Red Sea to the Indian Ocean south of Mozambique.
