Sažetak
The loess-palaeosol record at Süttő provides an excellent high-resolution archive of climate and environmental changes. Loess deposits with a thickness of 20 m cover the travertine at Süttő, in the northern part of Hungary, next to the right bank of the Danube River. The loess sequence is intercalated with two greyish stratified horizons, three brownish steppe-like soils and a pedocomplex, including a reddish-brown palaeosol covered by a chernozem-like palaeosol. Detailed infrared stimulated luminescence (IRSL) dating was carried out, revealing more or less continuous sedimentation from MIS 6 to MIS 2. Sedimentological and palaeomagnetic investigations have been performed to provide a high-resolution study of the Süttő loess-palaeosol sequence, in order to reconstruct the palaeoclimate- and environmental changes during the penultimate and last glacial cycles. Grain size and magnetic susceptibility (MS) records of the Süttő profile basically show similar pattern to those of other European loess sections. However, smaller differences are traced at Süttő, like more intensive deposition of coarser grained materials during MIS 6 to 4. The loess record at Süttő has a transitional position within the European loess belt, as its sediment deposited under an intermediate climate between the loess successions from the southern Carpathian basin, which accumulated under drier and the loess sequences from Western Europe, which developed under wetter climate during the Middle and Late Pleniglacial.
