On the basis of detailed textural investigations the depositional history of the study area has been established. The sediments in the bay and in the lagoon consist of a fine terrigenous quartz population and a coarser skeletal carbonate population, which have been mixed in various proportions. In order to gain size parameters that are more closely related to the hydraulic nature of depositional processes observed in the marine environment, grain size analyses were performed with an automatically recording settling tube system. The instrument was developed in the course of this study. Construction costs were kept extremely low without, however, impairing the scientific requirements of the instrument. Over 500 sediment samples were recovered on a closely-spaced grid; in each case, a size analysis was performed on the total sample and on the insoluble, terrigenous fraction. By subtracting the terrigenous size distribution from that of the total sediment, the relevant size parameters of the bioclastic component were calculated. In this manner 1500 individual size distributions were available for interpretation.","abstract_html":"This study deals with the physical aspects of sedimentation in Saldanha Bay and Langebaan Lagoon.
