Abstract:
In the biologically productive area on the Southwest Africa shelf a current process of diagenetic phosphorite formation occurs. Remains of phytoplankton are the main source of phosphorus in host bottom sediments. Phosphorus concentrates in nodules due to its redistribution in bottom sediments and precipitation from interstitial waters. Accumulation of the phosphate nodules, as well as of scattered fish bone debris in sediments occurs at sudden change in hydrological conditions and removal of fine sediment fractions due to increased bottom currents or during transgressions.
