Mantle anomalies beneath southern Africa: evidence from seismicSandPreceiver functions

To understand deep structure and processes beneath southern Africa, we apply the double-stacking version of the S receiver function (SRF) technique to the recordings of the South African Seismic Experiment. In this technique the wavefields of S and SKS are separated by space—time filtration, and the receiver functions are constructed separately for the S and SKS seismic phases. The results are con...
