A major revision of the presently accepted lithostratigraphic classification of the Swakop Group in the northern Central Zone is presented. The Lower Schist Unit, the Lower Marble Unit, the Upper Schist Unit and the Upper Marble Unit north of the Omaruru Lineament were previously correlated with the Khan Formation, the Rössing Formation, the Chuos Formation and the Karibib Formation respectively. The present investigation shows that the stratigraphic sequence in the northern Central Zone, from the exposed base of the Lower Schist Unit to the top of the Upper Marble Unit, is a stratigraphic unit above the Chuos Formation and thus a facies equivalent of the Karibib Formation. This correlation is based on the assumption that a similar stratigraphic sequence is found above the Chuos mixtite in the southern Central Zone. The suitability of the Chuos mixtite as a chronostratigraphic marker horizon is also discussed.
