Abstract

Abstract

The Profile Cape Spertivento, located in the Calabria peninsula of Italy, is composed of the Early Pliocene (5.3-4.8 Ma) Mediterranean marl-clay sediments. Based on the former work, a more accurate astronomically tuned timescale has been reconstructed for the sequence Cape Spertivento in this paper. Paleoproductivity proxies show that during the Early Pliocene, the increases of the Northern Hemisphere summer insolation always concurred with the increases of the organic carbon MAR, the high C/N ratios, the decreases of the carbonate MAR, and the negative excursions of G. obliquus δ¹⁸O and δ¹³C, which were probably caused by the enhanced rainfall, resulting from the strengthened African summer monsoon. Moreover, the strong African summer monsoon led to the flooding of the Nile River, increasing the discharge of continental nutrients and fresh water into the Mediterranean Sea. Strong precession and abundant semi-precession cycles are found in the spectrums of the proxy records, implying the tropical forcing of the African monsoon variability during the Early Pliocene.
