Nature research paper: Assembly of the basal mantle structure beneath Africa
Structure of the lower mantle and location of volcanic eruptions from 640 Ma to the present day.
High-velocity and low-velocity regions revealed by cluster analysis between 1,000 km and 2,800 km depth for 22 mantle flow model cases and seven tomographic models, and location of volcanic eruptions and kimberlites reconstructed from 640 Ma in 20-Myr increments. Results are shown starting 40 Myr into models starting after 600 Ma. Locations are shown for eruptions within 10 Myr of the considered age.
