Africa, Mauritania, Sahara Desert, nr. Ouadane (Atar). A Land Rover Defender TD5 Station Wagon descending on a rough gravel track from the ridge of the Guelb er Richat structure into its centre. --- Info: The Richat Structure is a prominent circular feature in the Sahara desert of Mauritania near Ouadane. It has attracted attention since the earliest space missions because it forms a conspicuous bull's-eye in the otherwise rather featureless expanse of the desert. The structure, which has a diameter of almost 50 kilometres, has become a landmark for space shuttle crews. Initially interpreted as a meteorite impact structure because of its high degree of circularity, it is now thought to be a symmetrical uplift (circular anticline or dome) that has been laid bare by erosion. Paleozoic quartzites form the resistant beds outlining the structure. The lack of shock metamorphism at the site further backs the latter claim. --- RELEASES AVAILABLE!
