Benthic foraminifera from the Orange-Luderitz shelf, southern African continental margin
An investigation of the benthic foraminifera in the surficial sediments of the continental shelf and upper slope off the Orange River mouth and the Namib Desert was undertaken as an adjunct to sedimentological and geophysical investigations being conducted by members of the Joint Geological Survey/U...

| description | An investigation of the benthic foraminifera in the surficial sediments of the continental shelf and upper slope off the Orange River mouth and the Namib Desert was undertaken as an adjunct to sedimentological and geophysical investigations being conducted by members of the Joint Geological Survey/University of Cape Town Marine Geoscience Group. 117 species in 65 genera of benthic foraminifera are described and illustrated, and five bathymetric zones are distinguished on the basis of faunal differences. A cluster analysis yielded clusters which correlated well with the three deeper bathymetric zones, but were ambiguous in the two shallower zones. Fauna interpreted as relict or reworked were present at a number of stations and were distinguished on the basis of glauconite or phosphorite infillings, anomalous, distributions, and tests which are worn, battered, and partially dissolved. Bibliography: p. 62-65. |
