Abstract
Southern Africa in particular is a very special natural laboratory for a journey through the Earth’s geo-archive. We can study tectonic processes on Early Earth as well as continental collision and breakup; and we learn how and why the African continent was blessed with mineral resources, such as diamonds or gold. With the beginning of the 20th century, geoscientists have started to set up observatories in South Africa to record earthquakes (since 1910) or conduct magnetic national surveys (Beattie, 1909). In Africa these geo-scientific pioneers found an ideal environment to study different tectonic units such as Cratons – ancient nuclei of continents, younger fold and orogenic belts as well as sediment basins and to investigate and classify their physical properties. The physical parameters applied were (i) elastic properties of rocks, which can be resolved using seismic and seismological observations and which allow to infer density information of rock formations, (ii) electrical conductivities which can be sensed using geo-electric, magnetotelluric (MT) und magnetometer-array measurements, (iii) magnetic properties, i.e. the ability of rocks to get magnetized, und (iv) the density of rocks which can directly be measured using gravity. The geophysics groups of the German Research Centre for Geosciences (GFZ) have been very active in South Africa since 2004 and have studies imprints of past continental collisions in the Earth crust and mantle along several traverses.
