Upper mantle structure beneath southern African cratons from seismic finite-frequency P- and S-body wave tomography

- Seismic model of southern Africa utilizes tomographic inversion of body wave data.
- The Kaapvaal and Zimbabwe fast keels reach depths of ∼350 and ∼250km, respectively.
- Limpopo belt represents a negative velocity perturbations down to a depth of ∼250km.
- Finite-frequency sensitivity kernels allow resolving relatively small-scale anomalies.
- Various resolution tests allow evaluation of the extent of smearing effects.
