Résumé
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,
δ
13
C
of loess-derived organic matter constitute reliable paleoclimatic proxies. We present here a new chronology of Nußloch loess sequence based on several
14
C
and TL-dates. Our data show high correlations with global climate effects (Vostok-[CO
2]) or semi-global (GISP2-
δ
18
O
) and thus offer, in this way, a new approach to establish accurate chronologies in continental sequences. Furthermore, using a deconvolution of the
δ
13
C
signal would provide a quantitative proxy of moisture supply and permit paleoprecipitation reconstructions.
