This issue of the Communications of the Geological Survey of Namibia deals with a variety of geological topics ranging from geochemistry (radio-isotopic dating), geomorphology (aeolian processes along the coast, structure of the Klinghardt Mountains, piping processes), geology (onyx travertine deposits of the Sperrgebiet, Proterozoic geology of north-western Namibia) and palaeontology (enigmatic tiny early Miocene African carnivorans, Eocene adapoid primates).
