Here, we present results from lake sediments of dark grey, laminated, organic-rich medium sand, on top of very dark grey gyttja at the site of Ejstrup, west of Kolding, Denmark. Based on pollen counts, the sediments were biostratigraphically classified as mid-Eemian. Despite the lake deposition, the assemblage of aquatic insect subfossils clearly indicates a river environment. The aquatic assemblage was rich, including five beetle taxa, 23 caddisfly taxa and 29 taxa of dipterans (non-biting midges, blackflies and brine flies). Specifically, analyses of the species' habitat traits point to a 15–25 m wide river, likely a tributary to a lake. This lowland river was likely fast-flowing, and meandering, with a sequence of riffle areas containing boulders, stones and gravel, separated by areas of sand, and bordered by silty/muddy areas along the banks. Furthermore, the riverbed may have contained a large amount of submerged dead wood but only sparse vegetation, due to an overall dense riparian canopy dominated by <i>Carpinus betulus</i>, <i>Corylus avellana</i> and <i>Alnus</i> sp. Based on the Trichoptera species, we reconstruct a mid-Eemian July mean air temperature of 18.1°C, that is, 1.2°C higher than the 1991–2020 average. The Eemian river environment, assumed to be unaffected by human influence, may serve as a useful reference for the present-day restoration of heavily anthropogenically impacted Danish and European rivers.</p>\u0000 </div>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"41 6","pages":"857-872"},"PeriodicalIF":1.9,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148700035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated. This paper presents palaeoenvironmental evidence for long-term social-economic change at Loch Clunie, contributing to a region with few well-dated environmental–archaeological sequences for the Roman Iron Age and beyond. Pollen, non-pollen palynomorph and sedimentological analyses are used to investigate patterns of environmental change and social activity from the later prehistoric period through to the late medieval era. The results indicate the presence of a local farming community pre-dating Roman incursions into Scotland. This is followed by a marked increase in barley cultivation either slightly before or during the early Roman Iron Age. The mid-Roman Iron Age is represented by a short-lived vegetation downturn and subsequent recovery. However, the most distinct change occurs during the late Roman Iron Age, represented by a pronounced decline to almost complete disappearance of barley from the third to fourth centuries AD, lasting approximately 400 years. Settlement–economic downturns are emerging at other sites in north-eastern Scotland with comparable temporal scales, although their causes appear to be complex. At Loch Clunie, there is no evidence to link this event to the Severan campaigns of AD 208–211. Indeed, this event appears slightly later. There is evidence, however, for a rise in lake levels, which could potentially be linked to Late Roman climatic deterioration.</p>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"41 6","pages":"915-932"},"PeriodicalIF":1.9,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jqs.70085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148700008","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}

Despite its importance, a distal co-ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass shows a broad chemical composition range, available refractive index and major-element glass data remain limited. This issue has made it difficult to identify the distribution area of the widespread Aso-3 tephra and utilize it as a marker layer. Consequently, the ability to synchronize terrestrial and marine records from Japan and the northwestern Pacific during the Marine Isotope Stage (MIS) 6/5 transition is limited. This study reports the identification of a previously unrecognized tephra layer (SKR tephra) within the basal part of the Furuya Formation in the Omaezaki area of central Japan as Aso-3 tephra. Petrological and geochemical analyses reveal that the SKR tephra consists of two compositionally distinct glass groups, whose major element composition closely corresponds to that of the Aso-3B unit within the Aso-3 pyroclastic flow deposits. Furthermore, the glass composition of SKR tephra matched that of cryptotephra (MD26.70 tephra) contained within a sample taken from marine core MD012422 off the coast of Shikoku at a depth of approximately 26.7 mbsf. The MD26.70 tephra was deposited during the MIS 6/5 transition, demonstrating that the SKR tephra represents a valuable stratigraphic marker synchronizing terrestrial and marine records for this period. Consequently, the SKR tephra contributes to refining the regional tephra chronology of central Japan.

Proposed mechanisms include Neolithic human transport via marine or overland routes or southward movement as a glacial erratic. Here, we combine sandstone provenance analysis with ice flow modelling to constrain potential sources and transport pathways. Ice sheet reconstructions show that southward transport vectors from northeast Scotland were highly localised, making precise source determination critical to evaluating glacial erratic transport plausibility. Candidate source areas farther south within the Orcadian Basin are more compatible with southward glacial dispersal, but show weaker correspondence with the detrital zircon age spectra that characterise the Altar Stone. By contrast, sandstones from Caithness on the mainland of northeast Scotland provide the closest match in zircon age structure; yet, modelled glacial transport from this region is predominantly towards the north-east, with a localised south-eastward pathway directed towards Dogger Bank. Glacial dispersal to Dogger Bank would reduce the anthropogenic transport distance required to Stonehenge from 700 km to 400 km. However, such a model raises an additional temporal problem, as Dogger Bank was inundated by post-glacial sea-level rise before the Altar Stone likely arrived at Stonehenge. Glacial transport may have provided an intermediate stage in the stone's journey, but alone cannot account for the final emplacement on Salisbury Plain.

In this paper, we combine lithostratigraphy, targeted foraminiferal assemblage analysis, and swath bathymetry to reconstruct the early phase of retreat of the LIS margin across the Broughton and Merchants fjord–cross-shelf–trough systems in southeastern Baffin Island, Canadian Arctic Archipelago. Radiocarbon dates based on mixed foraminiferal assemblages provide a revised deglacial chronology for southeastern Baffin Island.

In contrast, the Merchants Ice Flow stabilized on a grounding-zone wedge (GZW) between the LGM and 12.0 k cal a BP. Within the associated turbidite sequence downflow of the GZW, the transition between the presence of the foraminiferal species <i>Islandiella helenae</i> typically associated with ice-edge or seasonally open-water conditions and the absence of ice-rafted debris suggests the development of an ice shelf during this stabilization phase.

In conjunction with existing measurements of Burren karst features, we applied the new age constraint for postglacial exposure to refine long-term denudation rates, which are broadly similar to other maritime European karstlands. The close agreement between the ¹⁰Be surface-exposure ages and independent ages for Burren deglaciation also permits an empirical test of our chosen production rate and confirms it is applicable to this period and these latitudes.
