Röhrs & K. Weber Conference paper 264 Accesses 15 Citations Abstract A thick Proterozoic meta-playa sequence (Duruchaus Formation) is developed at the southern margin of the Damara Orogen. The meta-playa sediments exhibit a characteristic lithology and contain Palaeo-evaporitic minerals. After hot nappes of metamorphic rocks had been thrust from the Damara Orogen onto the playa sequence, a mobilisation of evaporitic carbonate layers and a hydrothermal-metasomatic metamorphism took place. The deformation along the southern margin of the Damara Orogen is largely controlled by the diapiric activity of the mobilised evaporites. The playa-sediments of the Duruchaus Formation correspond to similar rift deposits in other parts of Gondwana which all appear to be related to a phase of world-wide Proterozoic crustal stretching. Stratiform copper deposits and specific hydrothermal mineral concentrations are related to the playa environment and the metamorphism of the playa sediments.
