CLIMATIC SIGNATURE AND RADIOCARBON CHRONOLOGY OF MIDDLE AND LATE PLENIGLACIAL LOESS FROM EURASIA: COMPARISON WITH THE MARINE AND GREENLAND RECORDS

摘要

Recent investigations devoted to the Eurasian loess formations have provided an integrated high-resolution climatic sequence well radiocarbon dated between 13.4 and 42.5 kyr BP on charcoal and wood remains. Here, we show that the reproducible climatic signature of this loess sequence can be compared by proxy-correlation with the Greenland ice climatic signals, taking into account the distribution of the aeolian components in both records. This correlation allows situating with precision the series of ~(14)C dates obtained from loess with regard to the Greenland climatic sequence. In this way, comparing the atmospheric loess-derived ~(14)C chronology with the chronologies of the marine sequences becomes possible.
