“…Sand mobilisation at ca. 12.4 ka, as recorded in this study, correlates well with dune migration in southern Estonia (Kalińska-Nartiša et al 2016), which is further consistent with the cold GS-1 Greenland Event (Fig. 6; Steffensen et al 2008).…”

“…Previous studies, as well as this research, have demonstrated that the time span for aeolian sediment mobilisation seems to have been extended in this part of the ESB, contrary to in its western and central parts in the rest of Europe, where periods of aeolian mobility alternated with palaeosol development (Bertran et al 2011;Tolksdorf et al 2013;Vandenberghe et al 2013;Küster et al 2014;Beerten and Leterme 2015;Zieliński et al 2015Zieliński et al , 2016aHirsch et al 2017). In the Baltic region, so far, no buried soils have been found among the aeolian sediments of the NE ESB, except for discontinuous, lens-like and diffuse darkish organic material in eastern Latvia (Kalińska-Nartiša et al 2016;Kalińska 2019). At Iisaku, four phases of aeolian activity have been documented; however, the luminescence ages represent more of a continuous time span between ca.…”

Patchy aeolian landforms, representing the NE part of the European Sand Belt, occur in NE Estonia, between the Gulf of Finland and Lake Peipsi. The dunes are restricted to the former glacial lakebed, thus lying directly in contact with glaciolacustrine sediments, and have so far prompted different opinions regarding their genesis and age. This study aims to answer these open questions regarding the age and origin of these landforms and to provide information on the associated past sedimentary processes. To achieve this, we combine macro-scale (sedimentary structures and ground-penetrating radar survey) and micro-scale (grain-size, shape and character of quartz grain surfaces and mineral composition) studies with optically stimulated luminescence dating. The glaciolacustrine fines in the study area are wavy stratified, with the occurrence of mica horizons and prevalence of quartz sand grains with aeolian characteristics. Therefore, these sediments argue for near-standing/low-energy water conditions in the glacial lake, where allochthonous material was delivered by wind. A fall in the lake level and the occurrence of dry land on the northern coast of the regressive Late Weichselian Lake Peipsi favoured aeolian activity from ca. 13.5 to 10.5 ka in the region. The aeolian accumulation was brief-as apparent from the results of the micro-scale study-and lacks evidence of sediment recycling. Only easily-removable mica was deflated at the end of the aeolian depositional phase. Aeolian activity terminated ca. 10.5 ka due to a rising groundwater level that is apparent from the onset of paludification in the region.

“…In doing so, our results suggest that aeolian processes did not transform the sediment significantly. Such a trend has also been observed elsewhere in the Baltic States (Kalińska-Nartiša et al, 2016), and is additionally supported by the only limited number of grains produced in an aeolian environment (see below).…”

“…However, this luminescence date suffers from a large error range (>20 per cent) and thus remains questionable. Additionally, a single date from the interdune area at Bērzi yielded a date of 8.5±0.5 ka (Kalińska-Nartiša et al, 2016) and, although correlated rather with the cold 8.2 ka event (Rasmussen et al, 2007), it does match the error range based on results from the present study.…”

“…Less mechanically resistant feldsphatic elements in the sediments do not represent, in contrast, a typical aeolian record as observed in, for example, aeolian settings of multi-reworking, having been derived from pre-existing recycled sediments (Howari et al, 2007;Sweet & Soreghan, 2010;Hamdan et al, 2015;Woronko et al, 2015). However, a similar immature mineral record has been observed elsewhere in the Baltic States (Kalińska-Nartiša et al, 2016). Also sedimentary structures are attributable to either dry or moist depositional conditions, which might occur in aeolian settings.…”

In the Middle Gauja Lowland, northeast Latvia, dunes are distributed over a vast glaciolacustrine plain that formed during the retreat of the Fennoscandian ice sheet. Such a direct contact between aeolian and glaciolacustrine sediments can be used to infer depositional settings and decipher to what extent these sediments bear an aeolian component. Our proxies, although preliminary, reveal a limited range of variation in grain-size parameters, a significant presence of quartz grains with silica precipitation and matt-surface grains of various rounding degrees and massive structure combined with horizontal lamination. These are indicative of periglacial-aeolian depositional conditions in the foreland of the Linkuva ice-marginal zone. Sedimentary characteristics do not match a single luminescence date of 9.2±0.6 ka, which significantly postdates the minimum age of the Linkuva ice-marginal zone with 10Be ages between 15.4 and 12.0 ka. Whether deposition started directly after drainage of the Middle Gauja ice-dammed lake or if there is a gap of 2.8-6.2 ka is a matter of debate; only future studies at higher OSL resolution could resolve this.
