“…3). More or less pure loess layers of the Upper Pleistocene show a modal peak between 30 µm and 40 µm in most western European sequences (Krauß et al, 2018). But in unit III.II are no pronounced gains within the class of lower coarse silt.…”

“…To determine element concentrations, an 8 g aliquot of each sample (dried at 35 °C, homogenised, sieved at 63 μm, and dried for additional 12 h at 105 °C) and 2 g of wax binder (Fluxana Cereox) were mixed, homogenised, and pressed into a pellet at 19.2 MPa for 120 s. Sample analyses were conducted with an energy dispersive X-ray fluorescence (ED-XRF) spectrometer (SPECTRO XEPOS, SPECTRO Analytical Instruments GmbH). The element concentrations were used for, e.g., weathering proxies Rb/Sr, Ba/Sr (Krauß et al, 2016(Krauß et al, , 2018. The oxide concentrations were calculated by using element-specific conversion constants.…”

“…However, in consideration of the oxidative features in unit IV.I, pedogenic overprinting after the Luvisol formation should be considered. Since interglacials are long phases, soil complexes showing a polygenetic character frequently occur in LPS (Terhorst et al, 2001;Sprafke, 2016;Krauß et al, 2018). Even though the reduction of clay-sized particles, Fe 2 O 3 , a* and b* values, and the lighter material colour along with slight enhancements of CIA and CPA in unit IV.I could speak for an eluvial horizon, the gradual changes might also indicate a further, but less intensive, soil formation or pedogenic overprinting.…”

Loess-palaeosol sequences (LPS) represent important records of palaeoenvironmental dynamics throughout the Quaternary. During the Pleistocene's dry and cold phases, the Danube's riverbed was one of the major sources for loess sediments that built up LPS in southern Germany and southeastern Europe. Surprisingly, studies addressing Bavarian LPS along the Danube River often lack actuality. The Attenfeld site was one of them and is often cited as a typical LPS. Nevertheless, the site's previous interpretations are based on a few empirical data and field observations. Considering the site's closeness to the sediment's source area, the Alps, and the region's importance in Middle and Upper Palaeolithic migrational movements, those former renditions needed an evaluation. Therefore, we applied a multi-proxy approach (including analyses of grain-size distribution, element composition, and sediment colour attributes) combined with optically stimulated luminescence. Based on our findings, we conclude that the Attenfeld site's former interpretations might be too generalised. We identified units that were not mentioned by previous studies (e.g. Early Glacial dark greyish horizon). Field observations, sediment characteristics, and age estimates indicate sediment deposition of the dated units partly before MIS 4, which contrasts with previous interpretations. The results further demonstrate how sensitive LPS are to environmental settings and dynamics.

“…During the past decades, research on LPSs in Central Europe has mainly focused on last glacial records, occasionally with obtained ages below Eemian palaeosols (e.g. Kadereit et al, 2013;Moine et al, 2017;Fischer et al, 2021;Zens et al, 2018;Krauss et al, 2018;Rahimzadeh et al, 2021). Many Middle Pleistocene LPSs still lack stateof-the-art chronologies for individual loess and soil units, although palaeomagnetism and tephra stratigraphy are being applied where time intervals and material are present (e.g.…”

Abstract. Loess–palaeosol sequences (LPSs) remain poorly investigated in the southern part of the Upper Rhine Graben but represent an important element to understand the environmental context controlling sediment dynamics in the area. A multi-method approach applied to the LPS at Köndringen reveals that its formation occurred during several glacial–interglacial cycles. Field observations, as well as colour, grain size, magnetic susceptibility, organic carbon, and carbonate content measured in three profiles at 5 cm resolution, provide detailed stratigraphical information. Only minor parts of the LPS are made up of loess sediment, whereas the major parts are polygenetic palaeosols and pedosediments of varying development that are partly intersected, testifying to a complex local geomorphic evolution. The geochronological framework is based on 10 cm resolution infrared-stimulated luminescence (IRSL) screening combined with 18 multi-elevated-temperature post-IR IRSL ages. The luminescence ages indicate that two polygenetic, truncated Luvisols formed during marine isotope stages (MISs) 9(–7?) and MIS 5e, whereas unaltered loess units correspond to the last glacial (MISs 5d–2) and MIS 8. The channel-like structure containing the two truncated Luvisols cuts into > 2 m thick pedosediments apparently deposited during MIS 12. At the bottom of the LPS, a horizon with massive carbonate concretions (loess dolls) occurs, which may correspond to at least one older interglacial.

“…After the LGM with maximum ice sheet extent, the glacial termination took place, which was characterized by increased moisture and temperature (e.g., Clark et al, 2009;Denton et al, 2010). However, for the larger region around the Eifel, which includes Belgium (e.g., Vandenberghe et al, 1998;Rommens et al, 2007;Haesaerts et al, 2009Haesaerts et al, , 2016, northern France (e.g., Antoine et al, 2003), and the Rhine valley (e.g., Antoine et al, 2001;Rousseau et al, 2007;Frechen et al, 2010;Frechen and Schirmer, 2011;Krauß et al, 2018), and also for China (e.g., Lu et al, 2004;Sun et al, 2010), evidence of intensive loess deposits during the glacial termination and the Holocene is presented.…”

The climate in central Europe during the last 60 ka is characterized by rapid temperature and moisture changes and strong cold periods (Heinrich events). All these variations are preserved in sediments of marine and also some terrestrial archives. Here we present a continuous, terrestrial sediment record with almost all Greenland stadials and Heinrich events between 60 and 13 ka visible from carbonate roundness of the Eifel Laminated Sediment Archive Dust Stack-20 and CaCO3 data for central Europe. The carbonate roundness data show almost all stadials between 60 and 13 ka. CaCO3 data show a general transport system change with the beginning of Heinrich event 3. Since there are no carbonates west of the Auel Maar, we conclude that the eolian-transported grains were not transported by westerly but easterly winds. These postulated easterly winds during the last glacial maximum are supported by similar findings of previous works.
