Abstract

Abstract

An accurate timescale derived from benthic foraminiferal δ¹⁸O is crucial to paleoceanographic studies. In global oceans, there are few continuous δ¹⁸O records for the benthic foraminifers which span the past 5 Ma and have time resolution better than 5 ka. Such representative profiles have been established for ODP Site 659 in the Atlantic and ODP Site 846 in the east Pacific, but still have been absent in the"Western Pacific Warm Pool", an area playing an important role in global climate changes. Based on the benthic foraminiferal δ¹⁸O of ODP Site 1143 in the southern South China Sea, we establish a 5 Ma astronomical timescale for the west Pacific Plio-Pleistocene, with a time resolution of ~ 2-3 ka. The phases are fixed at 8 ka and 5 ka for the obliquity and precession bands respectively, and have been applied throughout the whole records. Obliquity and precession are calculated and treated as the tuning targets.An automatic orbital tuning method has been applied in this study, which is more efficient than those used at ODP Site 659 and 846. The results show that the 190.77 m long deep sea sediments in the South China Sea have recorded a paleoceanographic history of ~ 5.02 Ma, corresponding to 191 glacial/interglacial cycles. The tuned Brunhes/Matuyama paleomagnetic polarity reversal agrees well with an age of 0.78 Ma dated previously. The tuned ages for several planktonic foraminifer bio-events also agree well with published dates, and new ages for some other bio-events in the South China Sea are also estimated. The sedimentation rates calculated from this new timescale indicate that 2.9 Ma is a threshold for the sedimentation rate in the location of Site 1143. Before this time, the average sedimentation rate is ~ 39.5 m/Ma, with a small amplitude of ~ 50 m/Ma.After this time, the average sedimentation rate jumped to ~ 65.4 m/Ma, with an amplitude as large as 200 m/Ma. In addition, the sedimentation ratesin the southern South China Sea were higher during glacials or stadials but lower during interglacials orinterstadials, especially in the late Pleistocene period. This feature might be related to the global ice volume changes, which caused different erosion, denudation and transportation during glacials and interglacials.
