- •
Sampled upper mantle segments beneath the Nyos and Barombi localities are distinct.
- •
Barombi xenoliths represent juvenile lithospheric mantle with moderate deformation.
- •
Nyos xenoliths show evidence for higher degree of deformation and refertilization.
- •
Barombi xenoliths have higher concentration of water in NAMs.
- •
Calculated seismic anisotropies are in line with moderate measured SKS splittings.
