Crustal thickness and V p / V s ratio in NW Namibia from receiver functions: Evidence for magmatic underplating due to mantle plume‐crust interaction

Crustal thickness and V p / V s ratio in NW Namibia from receiver functions: Evidence for magmatic underplating due to mantle plume‐crust interaction

A seismological network was operated at the junction of the aseismic Walvis Ridge with the northwestern Namibian coast. We mapped crustal thickness and bulk V p / V s ratio by the H‐k analysis of receiver functions. In the Damara Belt, the crustal thickness is ~35 km with a V p / V s ratio of
