| Palynological data and other evidence suggest that the Upper Quaternary of the Cape Flats area can be subdivided chronostratigraphically into units that may be correlated with those of the Northern Hemisphere. Five intervals have been identified in the Middle Pleniglacial and formal names are introduced for these intervals. During three of them, the MILNERTON, KILLARNEY and BLOUBERG intervals, the vegetation had a xerophytic character and is comparable with that of the Holocene. During the intermediate periods, the SALTRIVER and DIEPRIVER intervals, an extension of the mixed Podocarpus (Knysna) forest to the Cape Flats area took place. These changes in vegetation can be explained by differences of effective precipitation. Two periods of sedimentation,... |
