Seismic Velocity Structure Of The Central Kaapvaal Craton

During the 1950’s several investigations made use of<br>Witwatersrand mine tremors in order to study the seismic velocity structure<br>of the Kaapvaal Craton, and derived simple one- or two-layered models<br>[Wilmore et al.., 1952; Gane et al., 1956; Hales and Sacks, 1959]. In this<br>study we take advantage of the advances in seismograph design, signal<br>processing and seismic interpretation techniques to derive a substantially<br>more detailed crustal model.
