    Description: The Bushveld Complex in South Africa is the world’s largest magmatic intrusion and at the same time the most important source of technologically important metals including chromium, vanadium and above all the platinum group elements. This flat, saucer-shaped intrusion has a volume of about 1 million km3 and by itself classifies as a Large Igneous Province. Within this vast intrusion, the platinum ores are mined from just two thin layers: the Merensky Reef and the UG2. Each of these is about one meter thick and both are continuous over hundreds of kilometers. The ore-bearing horizons, like other layers in the complex, clearly formed by igneous processes of crystallization in a magma chamber. The reseach challenges are to understand what processes accomplished the thousand-fold concentration of platinum from background levels to ore grade, and how ores were concentrated in such thin layers in a 9 kilometer-thick intrusion. Apart from providing answers to these scientific questions, the detailed mineralogical and microchemical studies of Bushveld ores at the GFZ are also being applied to find ways of improving the efficiency of ore beneficiation and platinum recovery.

    Description: In the context of global change, the Southern African region has to address great challenges in terms of its natural resources, in particular to cope with the impact of climate and land use change on the water balance, the soil fertility and the quantity of land suitable for common requirements. In the BMBF-funded project GeoArchives researchers from the German Research Centre for Geosciences, the Technical University of Munich and Senckenberg am Meer jointly exploit diverse Southern African archives of landscape development and climate change. The examination of these terrestrial and marine archives will provide deep insights into the climatic evolution and environmental conditions in Southern Africa during the Holocene. The highly interdisciplinary approach integrates geomorphology, soil science, sedimentology, inorganic and organic geochemistry, geomicrobiology and remote sensing. By assessing the possible impact of future climate change and land-use change on specific sensitive environments in Southern Africa we will provide future-oriented earth system management strategies with a geoscience rationale.
