Planktonic foraminifera of the Mediterranean Sea, supplement to: Jorissen, Frans J; Asioli, Alessandra; Borsetti, Anna Maria; Capotondi, Lucilla; de Visser, J P; Hilgen, Frederik J; Rohling, Eelco J; van de Borg, K; Vergnaud-Grazzini, Colette; Zachariasse, Willem-Jan (1993): Late Quaternary central Mediterranean biochronology. Marine Micropaleontology, 21(1-3), 169-189


A high-resolution biochronology is presented for the Late Quaternary of the central Mediterranean. In the Late Pleistocene-Holocene successions three assemblage zones are distinguished on the basis of frequency patterns of planktic foraminifera. The age of these zones is determined by Accelerator Mass Spectrometry (AMS)14C dating. The zonal boundaries are dated at 12,700 yr B.P. (the end of Termination Ia) and 9600 yr B.P. (the start of Termination Ib), respectively. The AMS dates show that major changes in the planktic and benthic realms occurred synchronously over wide areas, although records of individual species may show important regional differences. In the studied areas, resedimentation processes revealed by anomalous successions of14C dates, play a far more important role than indicated by the sedimentological and micropaleontological data. Possibly these processes contribute to the very high accumulation rates in the glacial Zone III. Although the AMS technique has increased the accuracy of14C-measurements, admixture of older carbonate may still lead to substantial age differences between areas with different sedimentary regimes.
