At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM. GM is a flat-topped hill in the Enns Valley, Styria (Austria), rising ∼200 m above the valley floor between Mesozoic carbonates (north) and crystalline basement units (south). Crystalline bedrock (phyllite, greenschist) is overlain by subglacial, deltaic, fluvial and glaciolacustrine sediments, with soft-sediment deformation (clastic dykes) and capped by LGM till. Outcrop, borehole, and electrical resistivity tomography data reveal a bedrock surface incised by a channel. The Middle–Late Pleistocene succession begins with the Lower Till, attributed to the Rissian glaciation (MIS 6), which reshaped a fluvially moulded bedrock surface by intense subglacial erosion, including meltwater activity. Above lies the Mitterberg Unit. The up to 100 m thick Dorf (Allo-)Member comprises delta foresets with slumps, rare dropstones and dead-ice contact structures, correlated to Termination II (MIS 6) by luminescence ages of 140±20 ka. The 10 m thick Zirting (Allo-)Member records fluvial deposition. The upper Frankenbichl (Allo-)Member consists mainly of interbedded lacustrine and deltaic sediments, showing overall aggradation. Luminescence ages of 47±8 ka suggest a lake formed in MIS 3 by a prograding alluvial fan under cold, ice-free conditions. The lacustrine succession records alternating delta progradation and dam-burst-caused regression. Uppermost Frankenbichl glaciolacustrine deposits reflect glacier-proximal settings marking the onset of Würmian Pleniglacial (MIS2) ice build-up. The LGM till unconformably overlies the Mitterberg Unit and forms drumlins.

The recent review (Chlachula &lt;span&gt;2026&lt;/span&gt;) provided an up-to-date synthesis of the largely fragmented information about chronology, palaeo-environmental conditions, cultural expressions and the main evolutionary trajectories of the cave Palaeolithic of the Urals. The study attempted to integrate the existing archaeological data—overwhelmingly published in the Russian language—into the broad territorial frame and regional geo-contexts of the karstic mountain system, following former summarizing studies on the early peopling of this area (Chlachula &lt;span&gt;2010&lt;/span&gt;; Pavlov &lt;span&gt;2022&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;The review Comments by Ruiz-Redondo (&lt;span&gt;2026&lt;/span&gt;) raised several points concerning the Urals' Palaeolithic exclusively associated with the cave art uncovered at two sites—Shulgan-Tash/Kapova Cave and Yamazy-Tash/Ignatievskaya Cave. Both sites were listed and repeatedly mentioned in the study (Chlachula &lt;span&gt;2026&lt;/span&gt;) with their geo-contextual and geoarchaeological characteristics, and chronologies (&lt;i&gt;op. cit&lt;/i&gt;.: tables 1, 2). Therefore, the statement that ‘The discussion of Kapova Cave is notably brief’ (Ruiz-Redondo &lt;span&gt;2026&lt;/span&gt;) is incorrect. The presentation of the archaeological monuments is balanced with the palaeoenvironmental and geoarchaeological concept of the review. The title of the commentaries of A. Ruiz-Redondo (‘Reassessing the role of the Urals in Palaeolithic cave-art research’) and the argumentation are somewhat misleading, as the cave art clearly was not the main subject of the published study.&lt;/p&gt;&lt;p&gt;In order to keep the review within reasonable limits, only the most essential information about the cultural records at Pleistocene-age cave occupation loci was provided, which inevitably led to the selection of the most relevant data only. As stated, the basis of the review and this reply was largely the Russian literature (105 original titles). The goal of the work was neither to present an exhaustive cataloguing of the entire Urals' Palaeolithic archives in their often vague temporal and natural contexts characteristic of some of the earlier (Soviet) investigations, nor to deal in detail with all single aspects of the Urals' Palaeolithic life and its material expressions—including the paintings on cave rock walls (parietal art).

The discovery of paintings in Kapova (= Shul'gan-Tash) Cave by the zoologist A. V. Ryumin in 1959 (Bader &lt;span&gt;1965&lt;/span&gt;) marked the first identification of UP rock art outside south-western Europe. This record was subsequently expanded with the discoveries of paintings in Ignatievskaya (Petrin &lt;span&gt;1997&lt;/span&gt;) and Serpievskaya II (Shirokov &amp; Petrin &lt;span&gt;2013&lt;/span&gt;) caves.&lt;/p&gt;&lt;p&gt;Strikingly, the first discovery beyond the well-established core region of Spain, France and Italy did not occur in its margins (for instance, Gruta de Escoural in Portugal was not found until 1963; see Santos &lt;span&gt;1964&lt;/span&gt;), but thousands of kilometres away, on the eastern edge of Europe. Moreover, the artworks exhibited features unknown in contemporary Magdalenian rock art sites of the Franco-Cantabrian region (Ruiz-Redondo &lt;span&gt;2016&lt;/span&gt;). Does this territory represent an independent centre for the invention of UP cave-art? Or does it reflect long-distance social networks linking it to regions in southern Europe? We have addressed these questions in recent publications (Ruiz-Redondo &lt;i&gt;et al&lt;/i&gt;. &lt;span&gt;2020&lt;/span&gt;; Ruiz-Redondo &lt;span&gt;2024&lt;/span&gt;), but the available evidence remains insufficient for a definitive answer. Based on the graphic record and radiometric dates from Kapova, we tentatively favour the second hypothesis (Ruiz-Redondo &lt;i&gt;et al&lt;/i&gt;. &lt;span&gt;2020&lt;/span&gt;: p. 985). In any case, the existence of a UP cave-art nucleus in the Urals renders the region exceptionally significant for the study of Eurasian UP societies.&lt;/p&gt;&lt;p&gt;In this light, the recent publication of a paper by J. Chlachula (&lt;span&gt;2026&lt;/span&gt;) offering an overview of UP cave sites in the Ural Mountains is to be welcomed. However, it fails to present adequately the two key sites—Kapova and Ignatievskaya—thereby misrepresenting their fundamental role in rock art research. In this short comment, a few issues concerning these two sites are addressed, with the aim of situating them according to their significance for the study of global UP cave-art.&lt;/p&gt;&lt;p&gt;The discussion of Kapova Cave is notably brief (~350 words), particularly given that it is, beyond question, the most important site included in the article, as the author himself acknowledges: ‘Shulgan-Tash (Kapova) Cave is a world-famous cave…’ (Chlachula &lt;span&gt;2026&lt;/span&gt;). As a consequence of this brevity, this description contains major omissions that impede an accurate understanding of the site's significance.&lt;/p&gt;&lt;p&gt;In terms of chronology, the author overlooks the extensive U-series dating undertaken on flowstones overlying several artworks. These analyses provide minimum ages of &lt;i&gt;c&lt;/i&gt;. 14.5 cal. ka BP for some paintings (Dublyansky &lt;i&gt;et al&lt;/i&gt;. &lt;span&gt;2018&lt;/span&gt;), a result fully consistent with the &lt;i&gt;c&lt;/i&gt;. 19–16 cal. ka BP radiocarbon chronology derived from the ca","PeriodicalId":9184,"journal":{"name":"Boreas","volume":"55 2","pages":"600-603"},"PeriodicalIF":2.9,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/bor.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen analyses and foraminiferal and ostracod analyses are combined to provide the evolution of relative sea-level change, supported by dinoflagellate cyst and diatom records. An independent chronology is established by correlation of the pollen record with that from the Bispingen laminated lake deposits in north Germany. Additional published sites from the area are included in a wider reconstruction of events. The evidence from five selected areas is assessed, with detailed evaluation of two critical time slices, respectively, in the <i>Corylus</i> pollen zone (E4) and that during the <i>Carpinus</i>-<i>Picea</i> zones (E5–E6). Ostracod analyses indicate that freshwater lakes initially existed in the basin prior to the marine inundation. This was followed by an early marine transgression. The timing of the first marine conditions varies across the basin. For example, in the southeast Baltic they were established in pollen zones E2–E3, and in the southwest Baltic they occurred at the base of E3, with fully marine conditions established in zone E4, continuing into E5. In the White Sea area marine conditions occurred in zone E2. In most areas, regression of the sea in the Baltic basin began late in zone E5–E6 and was occasionally followed by freshwater deposition in zone E7. Compared to the Holocene, the salinity of the basin was markedly higher during the period of maximum sea level (zones E4–E5) as shown by the foraminifera and other marine fossils. The Eemian transgression occurred through the Kiel Canal area in addition to the Danish straits-Kattegat seaway, indicating that a connection to the North Sea was present in the area during the interglacial sea-level maximum highstand.

Studying the response of coastal environments, such as submerged embayments, to sea-level changes in the past, can provide important insights into the response of present-day coastlines to future sea-level rise. Kalø Bay is an embayment situated in south-western Kattegat, north of the Aarhus Bay, Denmark. This shallow embayment was influenced by sea-level changes governed by global sea-level rise and glacio-isostatic rebound from the Scandinavian Ice Sheet during the latest Pleistocene and Holocene. In this study, we analyse the palaeolandscape in the bay to identify the depositional succession preserved in the bay and understand the dominant geological processes occurring after the last glaciation in response to sea-level changes. Four major depositional units reflect the variable environment in the bay as it changed from a glacial to proglacial setting through coastal and lagoonal infill stages, and gradually developed into a shallow marine environment as the area was inundated approximately 9–6 cal. ka BP. During a relative sea-level fall in the Mid- and Late Holocene, the deposits in the bay reversed to more coastal facies. Our study highlights the sensitivity of coastal embayments and their dynamic response to sea-level changes. Our results show how the bay changed from a wave-dominated setting in the Early Holocene to a current-dominated setting in the Late Holocene, and how the former glacial landscape and coastal deposits were affected differently by the sea-level rise and associated erosion and redeposition.

Extensive geomorphological evidence exists along the modern-day course of the Hvítá River in southwestern Iceland for floods from Glacial Lake Kjölur in the central highlands. Existing palaeoenvironmental records indicate flood drainage during the final phase of IIS retreat, but chronology is poorly constrained. This study reports Chlorine-36 cosmogenic nuclide exposure ages of seven bedrock surfaces along this flood route, marking the first time this method has been used to date Hvítá jökulhlaup evidence. Results yield four clustered ages that indicate flood drainage between 9.2 and 10.0±1.0 ka. When interpreted alongside geomorphological evidence and hypothesized ice sheet dynamics, this suggests either a single flood or multiple floods with decreasing sizes, indicating rapid ice sheet retreat. These results may also suggest that ice persisted in the region up to ~1 ka later than previous records show; however, this could be due to the ~1 ka uncertainty range in exposure ages. This pioneering application of exposure dating of the Hvítá floods yields insight into IIS deglaciation dynamics, flood landscape modification and hydrological response to glacier retreat in a warming climate, serving as a potential analogue to contemporary and future ice sheets worldwide.
