Fig. 4: Three-dimensional view of hotspots and cratons in central-eastern Africa.

High-velocity isosurfaces at +5% and low-velocity ones at \(-\)1.5% are plotted in the 80–350 km depth range. The 350 km \(\delta {V}_{S}\) map view is plotted at the depth. Kimberlite and lamproite sample locations are shown as red circles.
