Abstract:
One of the projects within the framework of Inkaba ye Africa, an earth system science initiative between German and South African research communities, is the Agulhas-Karoo Geoscience transect. This 800 km north-south onshore-offshore transect runs from the offshore Agulhas Plateau onto the South African coast, through the Cape Fold Belt, Beattie Magnetic Anomaly, the Karoo Basin, the Great Escarpment and into the Kaapvaal Craton. Among the number of geophysical measurements taken along the transect, are two wide-angle seismic lines collected in April and May 2005. These lines have both an on-shore, as well as off-shore, component. This enables us to penetrate the transition area between the two sections. Analysis of the western line shows that the transition from continental to oceanic crust is very complicated, and integration of our results with other geophysical measurements is necessary to describe it in detail.
