Here we present results of a multi proxy sedimentological and geochemical investigation of Kurortne loess-paleosol section from southwestern Ukraine, coupled with detailed optically stimulated luminescence (OSL) dating. OSL investigations were carried out on quartz grains of different grain sizes (4-11 \u03bcm, 63-90 \u03bcm and 90-125\u03bcm), using the single aliquot regenerative (SAR) protocol. The OSL dating results are in line with previous findings on dating loess-paleosol sequences along the Black Sea shore in Romania, as well as worldwide: (i) ages obtained on different grain sizes are in agreement for equivalent doses of less than 200 Gy, whereas for higher equivalent doses 4-11 \u03bcm ages underestimate the coarser fraction ages; and (ii) an inverse correlation between dated grain size fractions and saturation characteristics is reported. Our combined dating and sedimentological approach would confirm that the investigated uppermost 4.5 m at Kurortne cover the Last Glacial Cycle, adding important data in better constraining local and regional chronostratigraphic correlations. The application of the SAR protocol on 63-90 \u03bcm quartz grains on samples collected from the lower part of S1 soil (the Kaydaky unit) and from the Kaydaky/Pryluky units boundary produced ages of 123 \u00b1 10 ka and 85 \u00b1 6 ka, respectively. As the temporal range covered by these units in the Ukrainian Quaternary stratigraphic framework is still debatable, our results confirm the broad correlation of the Kaydaky-Pryluky paleosol units at Kurortne with the last interglacial (i.e., MIS 5). Dating the Uday and Bug loess units produced ages corresponding to MIS 4 and MIS 2, respectively, whereas the sample collected from the the Vytachiv unit provided an age of 37.7 \u00b1 2.4 ka, assigning this paleosol to MIS 3. On the basis of trends in the magnetic enhancement, the onset of pedogenetic processes likely commenced already around 20 ka, but the formation of the topmost S0 soil has begun after 13.8 \u00b1 1.0 ka.", "keywords": ["info:eu-repo/classification/ddc/550", "550", "loess chronostratigraphy", " OSL dating", " Last Glacial Cycle", " SE Europe", " Ukraine", "10.

So far it has been believed that the complex contains the Upper Paleolithic cave art images as well as portable art collection that resemble the instances of Upper Paleolithic worldview. Though this belief lacked the support of archaeological context and chronological attribution it remained neither proved nor disputed. However, the application of digital photogrammetric tools allowed to perform the sub-millimeter surface modeling of the rock art objects and to re-examine and reconsider the engravings that were previously attributed to Pleistocene. The modeling results presented in this article revealed the complete absence of figurative images for the collection of portable art specimens and the dubious character of those for the cave art one. Therefore, the whole collection should be reconsidered, studied and attributed according to the state of the art and contemporary archaeological record in the region. This contribution attempts to think over the possible Upper Paleolithic origin of the motifs from Kamyana Mohyla in the light of new data and proposes three hypotheses towards the understanding of the rock art assemblage from one of the caves in the complex.", "keywords": ["0601 history and archaeology", "06 humanities and the arts", "Composite beings; Kamyana mohyla; Photogrammetry; Rock art; Ukraine; Upper paleolithic;", "01 natural sciences", "0105 earth and related environmental sciences"]}, "links": [{"href": "https://iris.unive.it/bitstream/10278/5015525/1/1-s2.0-S1040618222003081-main.pdf"}, {"href": "https://iris.unito.it/bitstream/2318/1878502/1/1-s2.0-S1040618222003081-main.pdf"}, {"href": "https://doi.org/10.1016/j.quaint.2022.09.008"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Quaternary%20International", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1016/j.quaint.2022.09.008", "name": "item", "description": "10.1016/j.quaint.2022.09.008", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1016/j.quaint.2022.09.008"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2022-12-01T00:00:00Z"}}, {"id": "10.3390/land12020388", "type": "Feature", "geometry": null, "properties": {"license": "Open Access", "updated": "2026-04-15T16:20:54Z", "type": "Journal Article", "created": "2023-02-01", "title": "The Soils of Early Farmers and Their Neighbors in the Southern Buh Catchment (Ukraine): Micromorphology and Archaeological Context", "description": "<p>The problems regarding hunter-gatherer/early farmer interactions are quite an important topic in southeast European archaeology. According to the available data, the two economic subsistence systems have coexisted for some 2000 years during the 6th\uffe2\uff80\uff934th millennia cal BC (Telegin 1985; Lillie et al., 2001). In some areas, hunter-gatherer and early farmer sites are located just a few kilometers apart. The Southern Buh River valley has yielded evidence of Linear Pottery culture, early Trypillia and Trypillia B1 Neolithic settlements as well as hunter-gatherer sites with pottery attributable to the so-called sub-Neolithic or para-Neolithic (Haskevych et al., 2019; Kiosak et al., 2021). Trial-trenches have been opened within some of these sites, which have been radiocarbon-dated from Bern University laboratory (LARA). Soil samples for micromorphological analysis have been collected from these sites to interpret their paleogenetic formation. The soil development is attested since, at least, the beginning of the 5th mill BC, followed by the developed of chernozem soils, which was interrupted by an erosional episode in the end of 5th millennium BC. The available data show that the soils of early farmers arable as are the present day ones. The early farmers were able to exploit relatively heavy soils to cultivate wheat and barley as early as 5250\uffe2\uff80\uff935050 cal BC. In contrast, the sites of ceramic hunter-gatherers were often located on the soils which formed under wet conditions along seasonally flooded riverbanks, which were almost unsuitable for agricultural practices.</p>", "keywords": ["2.
