Crustal structures across the central Kaapvaal craton from deep-seismic reflection data

Eight deep-seismic reflection profiles (16 seconds TWT; generated by the vibroseis method) are presented and interpreted. The profiles cover a total of length of 500km and are projected into a common section that strikes northwest to southeast across the central part of the Kaapvaal Craton, including the Colesburg Magnetic Lineament (CML). The profiles clearly image the crust-mantle transition (Moho) between 11 and 13 seconds TWT (~ 36 to 41km).
