Since the beginning of the last century, Namibia has attracted scientists from all over the world to study the geology, uniquely exposed in the desert environment. Their research has shaped geological thinking worldwide, and led to the development of many new concepts. Research has been varied and widespread, as demonstrated by the numerous publications on Namibian geology. The guide provides a general introduction into the geological development of southern Africa and Namibia in particular, followed by general chapters on mineralogy, palaeontology, hydrogeology and mining. Special geological attractions of Namibia are then described in detail. The route descriptions are based on the 1999 simplified 1:2 000 000 geological map of Namibia, published by the Geological Society of Namibia. This simplified map is based on the 1:1 000 000 scale geological map of Namibia which was published by the Geological Survey of Namibia in 1980.
