Description :
The AA. report here data on the occurrence and high abundance of Rhizophora pollen, in association with taraxerol, from a high-resolution Congo fan core covering the last deglaciation. An age model based on C 14 dates enables the temporal changes in the percentage frequencies and flux of mangrove pollen, and in biomarkers, to be compared with pre-existing independent data on relative sea-level change in this region and with the hypismetric curve for the Congo margin. This approach therefore provides a basis with which to test the hypothesis that high quantities of mangrove pollen can be used as an indicator of transgression across tropical and sub-tropical continental shelves.
