Coastal phosphorus (P) burial represents a critical biogeochemical process regulating marine productivity and global P cycle, yet the mechanisms controlling its long-term sequestration during the Holocene remain poorly constrained. This study employs a multi-proxy approach (P speciation, AMS 14C dating, and XRF core scanning) to reconstruct P burial dynamics in the Southern Yellow Sea. Four depositional phases are identified, each controlled by sea-level rises and climatic forcing, with a critical transition at ∼7.5 cal ka BP. This transition marks a shift from terrestrial-dominated to marine-driven P burial following sea-level stabilization. During 8.0–4.6 cal ka BP (DU3), P burial was dominated by terrestrial inputs linked to riverine discharge. Since 4.6 cal ka BP (DU4), marine productivity became the primary driver of P burial, with phytoplankton dominating sedimentary P sequestration (>80 %). Mechanistic analyses reveal that sea-level rise amplified coastal erosion, simultaneously increasing terrestrial reactive P influx while reducing burial efficiency by ∼30 % through sediment reworking. Collectively, these findings quantitatively constrain sea-level-driven P transfer, highlight the critical role of phytoplankton-mediated burial during the mid-to late Holocene, and identify a tipping point in burial regimes at 7.5 cal ka BP. This study establishes a pre-anthropogenic baseline for coastal P cycling, critically informing models of modern eutrophication and ecosystem resilience under climate change.
沿海磷埋藏是调节海洋生产力和全球磷循环的重要生物地球化学过程，但其在全新世的长期封存机制尚不清楚。本研究采用多代理方法（P物种形成、AMS 14C测年和XRF岩心扫描）重建南黄海P埋藏动力学。确定了四个沉积阶段，每个阶段都受海平面上升和气候强迫的控制，关键转变发生在~ 7.5 cal ka BP。这一转变标志着海平面稳定后由陆地主导向海洋驱动的P埋藏的转变。在8.0 ~ 4.6 cal ka BP （DU3）期间，磷埋藏主要由与河流排放有关的陆地输入主导。自4.6 cal ka BP （DU4）以来，海洋生产力成为P埋藏的主要驱动力，浮游植物主导沉积P封存（> 80%）。机制分析表明，海平面上升加剧了海岸侵蚀，同时增加了陆地活性磷流入，同时通过沉积物改造使掩埋效率降低了约30%。总的来说，这些发现定量地限制了海平面驱动的磷转移，强调了全新世中晚期浮游植物介导的埋藏的关键作用，并确定了埋藏制度的转折点在7.5 cal ka BP。本研究建立了沿海磷循环的前人类活动基线，为气候变化下的现代富营养化和生态系统恢复模型提供了重要信息。

The fluvial development in the Sichuan Basin of southwestern China plays a significant role in the drainage evolution of the Yangtze River. The assumed initially west-flowing middle Yangtze River in the basin was reversed through gradual headward erosion by the lower Yangtze River via the Three Gorges area, resulting in a significant reorganization of the East Asian fluvial system. However, fluvial terrace chronology in the Sichuan Basin is poorly constrained, and the related drainage network development of the middle Yangtze River remains vague. Five distinct terrace levels of the Yangtze River were identified in the field, which could be efficiently correlated with terrace sequences from three major tributaries in the basin: Jialing Jiang, Tuo Jiang, and Min Jiang. This study presents in-situ cosmogenic nuclide 26Al and 10Be ages from these terraces to construct a robust chronology among different rivers, and more importantly, to build a reliable fluvial evolution relationship in the basin. Temporal and spatial variations in the terrace formation ages indicate that: (1) Five terrace levels from the Yangtze River in the southern basin were dated between 1.68 (+1.18/-0.56) Ma and 20.84 (+4.30/-5.03) ka. (2) The formation age of five terrace levels derived from the Jialing Jiang in the eastern basin is concentrated between 0.61 (+0.14/-0.13) Ma and 0.22 ± 0.20 Ma. (3) The highest terrace T5 of the Tuo Jiang in the middle basin was deposited at 1.24 (+2.86/-0.22) Ma. (4) Three terrace levels from the lower Min Jiang in the western basin were deposited between 0.81(+0.28/-0.26) Ma and 15.24 ± 1.21 ka.
Our new cosmogenic nuclide chronologies provide the first evidence for the Yangtze drainage network evolution in the Sichuan Basin. The Yangtze River and Min Jiang had been aggraded during 1.02–0.14 Ma in the western basin margin with an accumulation rate of 125 m/Ma and then incised after 0.14 Ma. The aggradation in front of the mountain may be attributed to both the active tectonics of the eastern Tibetan Plateau and climate cooling during the Middle Pleistocene Transition. Conversely, the Yangtze River and Jialing Jiang in the eastern basin and the Tuo Jiang in the middle basin cut down into bedrock more than 100 m since 1.68 Ma. The average incision rate of Jialing Jiang (360 m/Ma) in the last 0.6 Ma is higher than those of the Yangtze River (67 m/Ma) and Tuo Jiang (74 m/Ma) over longer timescales. Moreover, we conclude that the present-day eastward-flowing Yangtze River was established in the Sichuan Basin before 1.68 Ma, which further suggests that the downstream Three Gorges connection should have occurred before this point in time.

The global warming has led to the frequent occurrence of extreme weather events, and the study of paleoclimatic is crucial for understanding current climate changes. The Marine Isotope Stage 3 (MIS3) represents a relatively warm period within the Last glacial period, characterized by unstable climate conditions with multiple abrupt changes, similar to the present. The Asian summer monsoon (ASM) has a significant effect on the global climate, and its variations directly affect extreme climates and precipitation. Studying the changes in monsoon precipitation during MIS3 helps to understand the prediction of modern climate changes. This study, based on the analysis of optically stimulated luminescence (OSL) dating of loess in the central Yangtze River watershed, combined with environmental magnetism results, reconstructs the history of monsoonal precipitation changes in the upper-middle Yangtze River watershed during MIS3. The results indicate that the central region of the Yangtze River watershed experienced abundant precipitation during MIS3c, relatively less humid conditions during MIS3b, and a more humid pattern during MIS3a. The integration of other climatic forcing characteristics during MIS3 indicates that the variation of the East Asian summer monsoon (EASM) caused by the difference in the pressure gradient between land and sea under the regulation of solar radiation variations at low latitudes in the Northern Hemisphere is the main driving force for the dry and wet changes in the Yangtze River watershed, and the Indo-Pacific warm pool effect (IPWP) is the main source of the humidity changes in the watershed.The variations of the EASM and the strength of the IPWP effect are the primary cause of the 'humid-less humid-humid' characteristics in the hydrological changes of the Yangtze River watershed and their adjacent regions during the MIS3 stage.

Stratigraphic and geomorphic analysis paired with 10Be surface exposure dating provides evidence of extensive local ice growth in the Ruby Range, southwest Yukon, during the Late Pleistocene that contributed significantly to the extent of the St. Elias lobe of the northern Cordilleran Ice Sheet (CIS). Local ice growth occurred in cirques and on plateau surfaces above ∼1600 m producing significant valley glaciers in at least Marine Isotope Stages (MIS) 4 and 2. St. Elias lobe incursions of the CIS into the Ruby Range occurred during MIS 2 and MIS 4 based on stratigraphic evidence and surface exposure dates. No evidence was found for Early and Middle Pleistocene advances of the St. Elias lobe in contrast to areas affected by the Cassiar, Selwyn and Ogilvie lobes of the CIS. However, landforms and sediments on high-elevation upland surfaces suggest that ice was locally cold-based, making the delineation of glacial limits challenging. Non-glacial sediments containing fossil horse bones and newly described tephras were dated to MIS 3 and indicate Gladstone Creek was ice-free by approximately 50 ka, and the St. Elias lobe was reduced to an extent where drainage from Gladstone Creek was unimpeded. Ruby Range ice reached the mouth of Gladstone Creek after 29 ka then retreated beyond the stratigraphic study area prior to the arrival of the St. Elias lobe, possibly due an expanding St. Elias lobe cutting off moisture to the inland ranges. Alpine ice centers in the Ruby Range were responsive to climatic fluctuations and despite their location in the rain shadow of the St. Elias Mountains hosted significant advances contemporaneous with the Older Dryas and retreated from this position at 14.5–13.2 ka.
地层和地貌分析与10Be地表暴露年代测定相结合，提供了育空地区西南部红宝石山脉晚更新世广泛的局部冰生长的证据，这对北科迪勒兰冰盖（CIS）的圣埃利亚斯叶（St. Elias lobe）的范围做出了重大贡献。至少在海洋同位素阶段（MIS） 4和2中，环流和高原表面出现了局部冰生长，产生了显著的山谷冰川。根据地层证据和地表暴露日期，CIS的圣埃利亚斯叶侵入红宝石山脉发生在MIS 2和MIS 4。与受Cassiar、Selwyn和Ogilvie裂片影响的地区相比，没有发现圣埃利亚斯裂片早更新世和中更新世进展的证据。然而，高海拔高地表面的地貌和沉积物表明，冰是局部冷基的，这使得描绘冰川极限具有挑战性。含有马骨化石和新描述的tephras的非冰川沉积物的年代为MIS 3，表明Gladstone Creek在大约50 ka之前是无冰的，St. Elias lobe的减少程度使Gladstone Creek的排水畅通无阻。红宝石山脉的冰在29 ka后到达格拉德斯通溪口，然后在圣埃利亚斯裂片到达之前退到地层学研究区域之外，可能是由于圣埃利亚斯裂片的扩张切断了内陆山脉的水分。红宝石山脉的高山冰中心对气候波动做出了反应，尽管它们位于圣埃利亚斯山脉的雨影中，但与老仙女木时期同期发生了重大进展，并在14.5-13.2 ka从该位置撤退。

It was well established that the East Asian summer monsoon experienced a long-term weakening during the transition from precession minimum (Pmin) to maximum (Pmax), but how the leading monsoonal precipitation modes at interdecadal/interannual timescale superimposing on this weakening trend may vary remains unknown, owing to the dispersively distributed proxies and their coarse resolution. To address this challenge, we perform a transient global climate simulation at ∼1° resolution during 130–115 ka that encompasses the transition from Pmin (∼127 ka) to Pmax (∼116 ka). We demonstrated that the first leading mode of summer precipitation over eastern China shifted from monopole to dipole patterns during the Pmin-to-Pmax transition, with the second leading mode switching from dipole to tripole patterns. The shifts of precipitation modes were shaped by the southward shift of the regressed atmospheric circulation systems at interdecadal/interannual timescale during the Pmin-to-Pmax transition, which were further regulated by the long-term southward retreat and weakening of the East Asian summer monsoonal circulations due to decreased summer insolation. This elucidated interdecadal/interannual drought-flood variability superimposing on the long-term weakening of the East Asian summer monsoon, which may provide insight into how gradual orbital changes reorganize short-term precipitation variability and shed light on ecological civilizations over East Asia during the Pmin-to-Pmax transition.

The interaction between hunter-gatherer and early farming communities, and its relationship with climate change during the early to middle Holocene—corresponding to the transitional phase from the Late Paleolithic to the Neolithic—has become a central focus of interdisciplinary research in archaeology and environmental history. Foragers dominated central north China during the early Holocene, whereas farming groups who primarily engaged in millet cultivation expanded extensively after the middle Holocene. This expansion coincided with the contraction of forager habitats into ecotones unsuitable for rain-fed agriculture. Currently, the spatiotemporal trajectories and driving mechanisms of these dynamics remain poorly explained. Here we report new evidence from archaeological surveys, archaeobotanical analysis and radiocarbon dating from the Luoshan Mountain Region, which is located at the boundary between loess and deserts in northwest China. Our results reveal that foragers likely occupied this region during the late Pleistocene and the early Holocene. Two major phases of millet farmer settlement were ∼5000-4800 BP and ∼4100-3800 BP, and the northwestern boundary of prehistoric millet cultivation was found to surpass prior estimates by approximately 200 km. In contrast with previously published archaeological and paleoclimate records, we propose here that climate change was an important factor influencing the distributions of foragers and farmers in the desert-loess ecotone of north China between ∼11700 and 6500 BP. However, in the following millennia, from ∼6500 to 4000 BP, agricultural intensification instead emerged as the primary trigger for the expansion of farmer habitats.

However, in the following millennia, from ∼6500 to 4000 BP, agricultural intensification instead emerged as the primary trigger for the expansion of farmer habitats.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109662"},"PeriodicalIF":3.3,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145324582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how denudation rates vary over time is critical for assessing landscape stability, sediment budgets, and the impacts of climate and land-use change. Here, we reconstruct long-term catchment-wide denudation rates in the Murrumbidgee River, a major tributary within the Murray–Darling Basin, using in situ cosmogenic nuclides (10Be, 26Al) measured in sediments from palaeochannels and the modern river. To account for potential nuclide production during floodplain storage, we use U-series comminution ages to constrain sediment residence times, with storage depths treated as independent assumptions. Our modelling shows that sediment storage can substantially alter cosmogenic nuclide inventories, leading to underestimation of denudation rates by up to several fold when uncorrected. Although 10Be- and 26Al-derived rates are closely aligned under conventional assumptions, they diverge in storage-corrected models, with 26Al more strongly affected by radioactive decay during prolonged burial due to its shorter half-life. Nevertheless, long-term denudation rates remain low, ranging from 6 to 7 m Ma−1 under the conventional model (over ∼30–130 ka), and 4–10 m Ma−1 when accounting for sediment storage at depths ≥200 cm and residence times up to 480 ka. These values reflect catchment-scale processes operating over Late Quaternary timescales and contrast sharply with modern denudation rates, which are 5–10 times higher based on sediment yield data since the onset of widespread land-use change following British invasion. This divergence highlights a recent disruption to a long-standing regime of geomorphic stability in inland southeastern Australia. Our findings underscore the importance of accounting for sediment storage – through approaches such as comminution dating and paired-nuclide analysis – when interpreting cosmogenic nuclide-derived denudation rates in low-relief, storage-prone landscapes.
了解剥蚀率如何随时间变化对于评估景观稳定性、沉积物收支以及气候和土地利用变化的影响至关重要。在这里，我们利用在古河道和现代河流沉积物中测量的原位宇宙生成核素（10Be, 26Al）重建了穆伦比吉河（墨累-达令盆地的一条主要支流）的长期流域范围内的剥蚀率。为了考虑洪泛平原储存期间可能产生的核素，我们使用u系列粉碎年龄来限制沉积物停留时间，并将储存深度视为独立假设。我们的模型表明，沉积物储存可以极大地改变宇宙核素库存，导致在未经校正的情况下，剥蚀率被低估了几倍。尽管10Be-和26Al的衍生率在传统假设下是紧密一致的，但它们在存储校正模型中出现了分歧，26Al由于半衰期较短，在长时间埋藏期间受放射性衰变的影响更大。然而，长期剥蚀率仍然很低，在传统模型下（超过30-130 ka）为6 - 7 m Ma - 1，当考虑深度≥200 cm的沉积物储存和长达480 ka的停留时间时为4-10 m Ma - 1。这些值反映了在晚第四纪时间尺度上运行的流域尺度过程，并与现代剥蚀率形成鲜明对比。根据英国入侵后广泛土地利用变化开始以来的产沙量数据，现代剥蚀率高出5-10倍。这种分化突出表明，澳大利亚东南部内陆地区长期以来的地貌稳定性最近受到了破坏。我们的发现强调了考虑沉积物储存的重要性——通过粉碎测年和配对核素分析等方法——在解释低起伏、易于储存的景观中宇宙核素衍生的剥蚀率。

Valdegoba Cave (Burgos, Spain) is a site of longstanding importance for studying Neanderthal behaviour and anatomy within the interior of the Iberian Peninsula. Previous research at Valdegoba has explored various aspects of Neanderthal life histories, including records of mitochondrial DNA and oral microbiomes, use of the mouth for manual tasks, and resource acquisition – particularly specialised hunting of chamois. This latest article presents significant new insights into Neanderthal use of Valdegoba Cave based on the discovery of additional human remains, analysis of unpublished lithic artifacts, and examination of new geochronology results obtained using luminescence (single-grain OSL and pIR-IRSL) dating of sediments and amino acid racemisation (AAR) dating of mammal teeth. Our combined chronological dataset indicates that Neanderthal occupation of Valdegoba's Levels 4 and 5 (Unit D) occurred within, or close to, the transition between Marine Isotope Stage (MIS) 6 and 5, most likely between ∼140 and ∼120 ka. The newly discovered fifth distal phalanx from Level 5 presents clear Neanderthal morphology characterized by the expansion of the distal region (apical tuft), which is a typical Neanderthal trait. The updated lithic analysis of Valdegoba demonstrates the technological variability of Neanderthals in the Iberian Peninsula during the MIS 6/5 transition and their ability to adapt to diverse environments and resources. Our latest findings suggests that the Neanderthal group from Valdegoba Cave employed varied strategies for territorial and subsistence management towards the end of the Middle Pleistocene and beginning of the Late Pleistocene.

The Baltic Sea region has experienced numerous Pleistocene seismic events associated with glacial isostatic adjustment and icequakes, resulting in widespread sediment deformation and evidence of seismically induced liquefaction. Our investigations reveal clear indicators of such liquefaction, in the form of seismites (layers with seismogenic deformations), at eleven sites across the south-western, southern, and south-eastern Baltic Sea region. These include two locations in Germany (Weiβer Berg and Dwasieden), three in Poland (Siekierki, Ujście, and Rzucewo), two in Lithuania (Dyburiai and Slinkis), three in Latvia (Baltmuiža, Valmiera, and Rakuti), and one in Estonia (Pikametsa). The analysed sedimentary successions exhibit a variety of soft-sediment deformation structures (SSDS), such as injection structures, load structures (load casts, pseudonodules), ball-and-pillow structures, fragments of broken-up laminae, and flame structures, typical for liquefaction triggered by seismic shaking.
Our analysis combines detailed sedimentological investigations with numerical modelling of seismite formation and simulations of Coulomb failure stress changes under Pleistocene glacial conditions. This study aims to highlight that a wide range of SSDS in formerly glaciated sediments may indicate a seismogenic origin, and that some structures previously attributed to periglacial or glaciotectonic processes may require reinterpretation. We compile and document SSDS features from all eleven study sites to assist in identifying seismites and reconstruct the timing of palaeoseismic activity associated with the Fennoscandian Ice Sheet along the Baltic Sea coastline. Furthermore, we propose refined criteria for distinguishing seismogenic SSDS from those of nonseismogenic origin, especially relevant in intraplate regions of low present-day seismicity.
Our studies underscore the significance of seismically induced deformation structures as key archives of past seismicity and glacial/post-glacial geodynamics, summarising investigations conducted between 2013 and 2025, including those carried out as part of the GREBAL (Recognition of traces left by earthquakes in Pleistocene sediments affected by glacio-isostatic rebound in the Baltic Sea Basin) project. Seismites provide evidence of seismic activity that occurred between the MIS (Marine Isotope Stage) 6 and MIS 2 glaciations, including during their subsequent deglaciation phases. The results suggest that seismicity in the formerly glaciated intraplate areas of the Baltic Sea region was more frequent than previously recognised. This research offers new insights into the region's geological history, tectonic evolution, and glacial dynamics, advancing our understanding of the complex interactions between glacial processes and seismic activity in postglacial terrains.
