The Vendian-age Kuibis and Schwarzrand Subgroups of the Nama Group form a succession of shallow marine and minor fluvial sedimentary rocks exposed overmuch of central and southern Namibia. The sedimentology and sequence stratigraphy of the Kuibis and Schwarzrand Subgroups in the Witputs area are described. This study is part of a continuing work intended to place tighter environmental and geochronological constraints on the palaeontology and geochemistry of this important record of the Vendian earth and to investigate the relationship between the evolution of the Nama basin and the adjacent orogenic belts.
