摘要：

Due to its high accumulation rate, the loess sequence of Nussloch (Rhine Valley. Germany) is well suited to a high-resolution study of continental paleoenvironmental changes over the last climatic cycle for northwestern Europe. As carbon isotope ratios of plants depend on environmental variations, delta(13)C of loess-derived organic matter constitute reliable paleoclimatic proxies. We present here a new chronology of Nussloch loess sequence based on several C-14 and TL-dates. Our data show high correlations with global climate effects (Vosrok-[CO2]) or semi-global (GISP2-delta(18)O) and thus offer, in this way, a new approach to establish accurate chronologies in continental sequences. Furthermore, using a deconvolution of the delta(13)C Signal would provide a quantitative proxy of moisture supply and permit paleoprecipitation reconstructions.
