AbstractThere is an ongoing controversial discussion as to whethern-alkane lipid biomarkers—and organic matter of loess in general—reflect a synsedimentary paleoenvironmental/climate signal or whether they are significantly affected by postdepositional “contamination,” for example related to root and rhizomicrobial activity. In order to address this issue at our study site (the Middle to Late Weichselian loess-paleosol sequence Gleina in Saxony, Germany), we determined and compared radiocarbon ages of bulkn-alkanes and sedimentation ages, as assessed by optically stimulated luminescence (OSL) dating. The bulkn-alkanes of the four dated samples yielded calibrated14C ages ranging from 24.1 to 49.7 cal ka BP (95.4% probability ranges). While the three uppermostn-alkane samples are well within the range or even slightly older than the OSL-inferred sedimentation ages, the lowermostn-alkane sample is slightly younger than the OSL ages. There is hence little or no evidence at our study site forn-alkanes in loess-paleosol sequences being significantly “contaminated” by deep subsoil rooting or microbial processes. We propose a14C isotope mass balance calculation for estimating such contaminations quantitatively. Radiocarbon dating of bulkn-alkanes might have great potential for Quaternary research, and we encourage further comparative14C and OSL studies.
