Abstract

During the CNR cruise BS 79 performed in 1979, two gravity cores, BS 79-33 and BS 79-38, were recovered in the Cefalù Basin, in the southern part of the Tyrrhenian Sea. Qualitative and quantitative investigations on benthic and planktonic foraminifera, oxygen and carbon stable isotope measurements have been carried out on the cores. This multidisciplinary investigation has allow us to recognize a continuous, undisturbed stratigraphic sequence of about 20 ka B.P. The intervals of sediment related to the Last Glacial Maximum (LGM), to the Termination IA and Termination IB and to the Younger Dryas (YD) have been recognized. These steps are synchronous with those reported in other parts of the west Mediterranean Sea (e.g.: Strait of Sicily). Four major planktonic assemblages relowed to establish a local biozonation corresponding to the climatic variations obtained fromδ 18O dating. Difficulty in the interpretationδ 13C of the records is difficult, due to insufficient knowledge of the parameters influencing foraminifera assemblages in the Tyrrhenian Sea.

Riassunto

Durante la crociera BS 79 del CNR svoltasi nel 1979 sono state prelevate due carote a gravità, la BS 79-33 e la BS 79-38, nel Bacino di Cefalù, nel Mar Tirreno meridionale. Sulle carote si sono svolte analisi qualitative e quantitative su foraminiferi bentonici e planctonici e analisi isotopiche dell’ossigeno e del carbonio. Tali studi multidisciplinari hanno consentito di riconoscere una sequenza continua ed indisturbata degli ultimi 20 ka circa. Sono stati individuati l’Ultimo Massimo Glaciale (LGM), le Terminazioni IA e IB e loYounger Dryas (YD). Questi eventi sono correlabili con quelli rilevati in altre regioni del Mediterraneo occidentale (es.: Stretto di Sicilia). Sono stati riconosciuti quattro maggiori assemblaggi planctonici che hanno permesso di stabilire una locale biozonazione corrispondente alle variazioni climatiche ottenute con le analisi alδ 18O. Le difficoltà nell’interpretazione delδ 13C dipendono da una conoscenza non sufficientemente dettagliata dei parametri che influenzano le associazioni di foraminiferi nel Mar Tirreno.
