Abstract
Due to its high accumulation rate, the loess sequence of Nu{loch (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, C of loess-derived organic matter constitute reliable paleoclimatic proxies. We present here a new chronology of Nu{loch loess sequence based on several C and TL-dates. Our data show high correlations with global climate e!ects (Vostok-[CO ]) or semi-global (GISP2-O) and thus o!er, in this way, a new approach to establish accurate chronologies in continental sequences. Furthermore, using a deconvolution of the C signal would provide a quantitative proxy of moisture supply and permit paleoprecipitation reconstructions. 2000 Elsevier Science Ltd and INQUA.
