Abstract provided by author:
Both the marine and riverine deposits lie unconformably on the rocks of the Precambrian Gariep Group. The succession of the latter within the area studied is briefly described
The adjacent marine deposits, which form a raised beach complex on the coast, are described and the relationship between these marine and riverine deposits is examined
It is concluded that the marine deposits are considerably younger than the riverine deposits, which had previously been considered virtually contemporaneous. It is thought that the marine beaches range from Mid- to Late-Pleistocene, while the riverine deposits are possibly? Plio- Pleistocene to Early Pleistocene in age
