Comparison of High-Resolution 14C and Luminescence-Based Chronologies of the MIS 2 Madaras Loess/Paleosol Sequence, Hungary: Implications for Chronological Studies

Numerous loess/paleosol sequences (LPS) in the Carpathian Basin span period of Marine Isotope Stage (MIS) 2 and last glacial maximum (LGM). Nevertheless, only two known records—Madaras Dunaszekcső—preserve highly resolved records with absolute chronologies minimal uncertainties, which enable meaningful assessment feedbacks short-term climatic fluctuations over this period. The Madaras profile is located at northern margin fringe Bácska loess plateau; Dunaszekcső, on Danube to its west, yields a chronology built 100 14C dates yet spans part MIS 2, missing half LGM including peak. Here, we add previously published for (15 dates) an additional 17 luminescence ages. Resulting age models solely quartz OSL feldspar pIRIRSL data underestimate based chronology, likely inaccuracies related signal behavior; observe underestimations associated unusual behavior significant loss, phenomenon also observed Serbian Romanian loess, may relate non-sensitized grains from proximal sources. Our new provides higher resolution than hitherto possible, yielding consistent sigma uncertainties ~150–200 years throughout entire sequence. study indicates that addition further not increase chronological precision significantly.
