Abstract

V originále

High-resolution multidisciplinary investigation of key European loess-palaeosols profiles have demonstrated that loess sequences result from rapid and cyclic aeolian sedimentation which is reflected in variations of loess grain size indexes and correlated with Greenland ice-core dust records. This correlation suggests a global connection between North Atlantic and west-European air masses. Herein, we present a revised stratigraphy and a continuous high-resolution record of grain-size, magnetic susceptibility and organic carbon d13C of the famous of Dolní Vestonice (DV) loess sequence in the Moravian region of the Czech Republic. A new set of quartz OSL ages provides a reliable and accurate chronology of the sequence’s main pedosedimentary events. The grain size record shows strongly contrasting variations with numerous abrupt coarse-grained events, especially in the upper part of the sequence between ca 20-30 ka. This time period is also characterised by a progressive coarsening of the loess deposits as already observed in other western European sequences. The base of the DV sequence exhibits an exceptionally well-preserved soil complex composed of three chernozem soil horizons and 5 aeolian silt layers (marker silts). This complex is, at present, the most complete record of environmental variations and dust deposition in the European loess belt for the Weichselian Early-glacial period spanning about 110 to 70 ka, allowing correlations with various global palaeoclimatic records. OSL ages combined with sedimentological and palaeopedological observations lead to the conclusion that this soil complex recorded all of the main climatic events expressed in the North GRIP record from Greenland Interstadials (GIS) 25 to 19.
