Despite a long history of geologic research in the European Eastern Alps, Quaternary landscape evolution before the Last Glacial Maximum (LGM) remains poorly constrained due to the scarcity of dated sedimentary archives, particularly in inneralpine regions. In this study, we reinvestigate an 880-m-long drill core from Bad Aussee (Styria, Austria), originally drilled for salt exploration. Sedimentological, geochemical, and geochronological analyses allow us to identify three major depositional units spanning the last two glacial cycles. The succession starts with glaciolacustrine deposition during the penultimate glaciation (Rissian, Marine Isotope Stage 6), consisting mainly of glacially sourced material of local provenance (carbonates and evaporites). In contrast, the >500-m-thick overlying deltaic and lacustrine deposits (Early to Middle Würmian) indicate a source area dominated by crystalline rocks. This observation suggests that, for a prolonged period between the Last Interglacial and the Late Würmian (MIS 2), the Upper Enns Valley drained into today's Traun Valley, crossing the present-day drainage divide. Furthermore, the lack of glacial deposits indicates that glacial advances during this phase did not reach the Bad Aussee Basin. On top of the succession, a carbonate-rich subglacial till can be attributed to the LGM. While questions regarding the formation mechanism of this exceptionally deep and confined Quaternary basin remain, our results challenge the previously suggested model of subglacial dissolution and subsequent formation and rapid infill of a deep lake. Salt-related syndepositional subsidence could serve as an alternative explanation for the observed stratigraphy.
尽管在欧洲东阿尔卑斯进行了长期的地质研究,但由于缺乏年代沉积档案,特别是在阿尔卑斯内部地区,末次盛冰期之前的第四纪景观演变仍然缺乏限制。在这项研究中,我们重新研究了来自Bad Aussee (Styria, Austria)的一个880米长的岩心,该岩心最初是为盐勘探而钻探的。沉积学、地球化学和地质年代学分析使我们能够确定跨越最后两个冰期旋回的三个主要沉积单元。演替开始于第二次冰期的冰湖沉积(Rissian,海相同位素阶段6),主要由当地的冰川来源物质(碳酸盐和蒸发岩)组成。而上覆500 m厚的三角洲和湖相沉积(早-中眠世)则是一个以结晶岩为主的烃源区。这一观察结果表明,在末次间冰期和晚冰河期(MIS 2)之间的一段很长的时间里,上恩斯山谷穿过今天的分水岭,流入今天的特劳恩山谷。此外,冰川沉积物的缺乏表明,这一阶段的冰川推进没有到达巴德奥西盆地。在演替的顶部,一个富含碳酸盐的冰下坡地可归因于LGM。虽然关于这个异常深且受限的第四纪盆地的形成机制仍然存在疑问,但我们的结果挑战了先前提出的冰下溶解和随后形成和快速填充深湖的模型。与盐有关的同沉积沉降可以作为观测到的地层的另一种解释。

Paleoeconomy and mortuary practices in the Mediterranean Copper Age: zooarchaeology of the Bell Beaker assemblage from Padru Jossu, Sardinia (Italy) 地中海铜器时代的古经济和墓葬实践:意大利撒丁岛帕德鲁·约苏的钟烧杯动物考古

The Bell Beaker phenomenon, as evidenced by its distinctive material culture, is regarded as a pivotal period of intensified connectivity in Western Europe and the Western Mediterranean, spanning several centuries from the mid-3rd millennium BC to different periods in different regions. The nature and mechanisms behind the diffusion of its markers have been under interpretive scrutiny for many decades, until the recent contribution of stable isotopes and ancient DNA supporting the reconstructed picture of an increasingly mobile lifestyle. Some aspects, however, remain elusive. This study addresses two key areas: the economic practices related to livestock, and the funerary practices recorded at the burial site of Padru Jossu in central southern Sardinia, with special reference to animal offerings. Whereas the context's human remains have been only partially morphologically and isotopically studied, the results of the comprehensive examination of the faunal remains are presented here. A substantial prevalence of caprines, found alongside and among the human remains, provided clues that could reflect management practices and ceremonial preferences across several generations. Data on age and skeletal districts provide clues regarding ceremonial use that are interpreted in light of available stable isotopic results, and then compared with evidence from other sites in the area across Sardinian prehistory and other surrounding Mediterranean regions. This illuminates apparent trends in management practices and contributes to our knowledge of Mediterranean Bell Beaker practices and economy, including potentially symbolic choices, adding to our knowledge of the diverse funerary rituals characterizing this cultural phenomenon.
从公元前3千年中期到不同地区的不同时期,贝尔烧杯现象被认为是西欧和西地中海加强联系的关键时期,其独特的物质文化证明了这一点。其标记物扩散背后的性质和机制几十年来一直处于解释性审查之下,直到最近稳定同位素和古代DNA的贡献支持了一种日益流动的生活方式的重建图景。然而,有些方面仍然难以捉摸。本研究涉及两个关键领域:与牲畜有关的经济实践,以及撒丁岛中南部Padru Jossu墓地记录的丧葬实践,特别提到了动物祭品。虽然环境中的人类遗骸只进行了部分形态学和同位素研究,但这里介绍了对动物遗骸进行全面检查的结果。在人类遗骸的旁边和中间发现了大量的山羊,这为反映几代人的管理实践和仪式偏好提供了线索。年龄和骨骼区域的数据提供了关于仪式使用的线索,这些线索是根据现有的稳定同位素结果来解释的,然后与撒丁岛史前地区和其他周围地中海地区的其他遗址的证据进行比较。这阐明了管理实践的明显趋势,并有助于我们了解地中海贝尔烧杯的实践和经济,包括潜在的象征性选择,增加了我们对这种文化现象特征的各种丧葬仪式的了解。

Romito 9: A new Palaeolithic burial from Grotta del Romito (Calabria, Italy) 罗米托9号:在意大利卡拉布里亚的罗米托Grotta del Romito发现的一个新的旧石器时代墓葬

During recent excavations at Grotta del Romito (Papasidero, northern Calabria, Italy), a new Upper Palaeolithic burial—designated Romito 9—was identified. The burial pit had been partially disturbed ab antiquo, resulting in an altered depositional context. The burial pertains to a female individual, approximately 11–12 years of age, and is associated with an archaeological layer dated to 16,129 ± 100 uncal BP (19,809–19,157 cal BP, 2σ), corresponding to the evolved phase of the local Epigravettian culture. Romito 9 presents a richly furnished burial, featuring the use of red ochre and abundant ornamentation. It represents the earliest known funerary evidence chronologically positioned between the Gravettian burials of Italy and those of the Final Epigravettian. This intermediate position underscores the continuity of complex ceremonial traditions characteristic of the Gravettian, prior to the ritual simplification documented in southern Italy during the Final Epigravettian. The individual, likely a prepubertal female at the time of death, exhibits dental dimensions more closely aligned with Middle Upper Palaeolithic (MUP) individuals than with those from the Late Upper Palaeolithic (LUP). Her estimated adult stature would have exceeded that of Romito's LUP adult females by approximately 20 cm, approaching the maximum values recorded for LUP females and aligning closely with the average stature of LUP adult males from the site. Given the paucity of comparative data for LUP individuals of the same age range, her body proportions and overall dimensions appear to be more consistent with MUP populations. A meticulous excavation strategy, combined with detailed post-excavation analysis of the funerary context, facilitated the reconstruction of both taphonomic and post-depositional processes. This work further enabled the creation of a visual model illustrating the original position of the buried individual and portions of the associated ornamentation.
最近在意大利卡拉布里亚北部帕帕西德罗(Papasidero)的Grotta del Romito发掘中,发现了一个新的旧石器时代晚期墓葬,命名为Romito 9。墓坑部分被反方向扰动,导致沉积环境发生改变。该墓葬为一具女性个体,年龄约11-12岁,所处考古层的年代为16,129±100伯伯BP (19,809-19,157 cal BP, 2σ),与当地Epigravettian文化的进化阶段相对应。Romito 9呈现了一个装饰华丽的墓葬,以使用红赭石和丰富的装饰为特色。它代表了已知最早的丧葬证据,按时间顺序定位在意大利的格拉韦提墓葬和最后的埃格拉韦提墓葬之间。这种中间位置强调了格拉维特人复杂仪式传统特征的连续性,在最后的埃格拉维特时期,在意大利南部记录的仪式简化之前。该个体在死亡时很可能是一名青春期前的女性,其牙齿尺寸与中上旧石器时代(MUP)的个体更接近,而不是与晚上旧石器时代(LUP)的个体更接近。她估计的成年身高将超过Romito的LUP成年女性大约20厘米,接近LUP女性记录的最大值,并与该地点LUP成年男性的平均身高非常接近。鉴于缺乏相同年龄范围的LUP个体的比较数据,她的身体比例和整体尺寸似乎与MUP人群更一致。细致的挖掘策略,结合对殡葬环境的详细挖掘后分析,促进了地貌学和沉积后过程的重建。这项工作进一步创造了一个视觉模型,说明了被埋葬的个人的原始位置和相关装饰的部分。

The European Middle Paleolithic laminar technologies can be divided into Levallois and non-Levallois blade production. Despite the abundance of detailed publications about the reduction strategies and their differences, only a few discuss the causes of their variability. The paper addresses the variability of laminar technology from the aspect of its use, mobility, and technological organization of Neanderthal communities in the Central Balkans in MIS 3. Results of use-wear analysis of Levallois and non-Levallois laminar products are compared with metrics, frequency, and raw material procurement, as indicators of their potential for carrying and reshaping with an aim to represent the fundamental differences between curated and expedient technological strategies. Integrated results, considered in the wider regional context, contribute to the understanding of laminar variability in the Middle Paleolithic, as the reconstruction of the technological behavior of Neanderthal communities.

The new key sections of the Last Interglacial transgression in the Eurasian Arctic (Eastern White Sea): paleoenvironmental reconstructions and interregional correlations 欧亚北极(东白海)末次间冰期海侵新关键剖面:古环境重建与区域间对比

New stratigraphic, micropaleontological and geochronometric (optically stimulated luminescence, OSL) data for the basal sediment units of the six sections around the periphery of the Kuloi Plateau (Zimnii Coast and Soyana-Kuloi River valley) assign them to the end of MIS 6 – MIS 5 Boreal (Eemian) transgression in the eastern White Sea Region. Most of the studied Boreal marine beds are composed of two units, with the dark grey fossiliferous silty clay overlain by beige and light grey loose (sand and gravel) variously bedded material. Presumably high sedimentation rates due to the proximity to the Kuloi Plateau resulted in the low total abundance of microfossils and their relatively monotonous taxonomic composition. Benthic foraminifers display almost equal proportions and coexistence of ecologically different groups occurring in the Arctic shelf seas, from shallow inner shelf inhabitants to relatively deep-water ones. Rare ostracods are represented by typical dwellers of the Arctic mid-outer shelf areas. Similar to benthic foraminifers, dinocysts show a mixture of heterotrophic, including cryophilic, and autotrophic forms. The constant presence of freshwater green algae points to river runoff influence. Findings of rare polar and subpolar planktonic foraminifers together with benthic foraminifer species Cassidulina neoteretis allow assuming periodical inflows of subsurface Atlantic-derived water. Altogether, this gives evidence for an Arctic-type marine basin likely corresponding to the early stage of the transgression probably including the local highstand prior to regression. The age assignment of these beds is supported by OSL dates from overlying sandy layers generally ranging between 140 and 87 ka, with possibly older (MIS 7) age in one of the Zimnii Coast sections.
The cross-correlation through the Northern Eurasia enables us to state that the common characteristic of the Last Interglacial (LIG) marine sedimentary succession is its two-unit structure. The lower unit corresponds to the early stage of inundation, the upper indicates the littoral sedimentary setting during the stillstand and regressive stage. The substantial range of available dates from 160 to 80 ka, encompassing the end of the MIS 6 glaciation, its degradation, and part of the MIS 5 stage, precludes precise determination of the duration of the Boreal transgression.
The “gap” in the occurrence of the LIG marine deposits in the northeastern Eurasia along the Laptev and western East Siberian coasts might be related to the formation and existence of the glacioisostatic forebulge at the periphery of the MIS 6 ice sheets in combination with local neotectonic movements.
对库洛伊高原外围6个剖面(Zimnii海岸和Soyana-Kuloi河流域)的基底沉积物单元进行了新的地层、微古生物学和地质年代学(OSL)研究,将其确定为白海东部地区MIS 6 - MIS 5北纬(Eemian)海侵末期。大多数研究的北方海相床由两个单元组成,深灰色的化石粉质粘土覆盖着米色和浅灰色的松散(砂和砾石)各种层状物质。可能由于靠近库洛伊高原,沉积速率高,导致微化石总丰度低,分类组成相对单一。底栖有孔虫在北极陆架海洋中,从浅层陆架居民到相对较深的陆架居民,显示出几乎相同的比例和生态不同群体的共存。罕见的介形类以北极中外陆架地区的典型居民为代表。与底栖有孔虫类似,二囊虫表现出异养的混合,包括嗜冷和自养形式。淡水绿藻的持续存在表明河流径流的影响。罕见的极地和亚极地浮游有孔虫以及底栖有孔虫Cassidulina neoteretis的发现允许假设大西洋地下水的周期性流入。总的来说,这提供了一个北极型海相盆地的证据,可能对应于海侵的早期阶段,可能包括回归之前的局部高地。这些层的年龄分配由上覆砂层的OSL日期支持,通常在140 - 87 ka之间,在Zimnii海岸的一个区段可能更老(MIS 7)。通过欧亚大陆北部的相互对比,我们认为末次间冰期海相沉积演替的共同特征是其双单元结构。下部单元对应早期淹没期,上部单元代表静止期和退潮期的滨海沉积环境。从160 - 80 ka的大量可用日期,包括MIS 6冰期的结束、其退化和MIS 5阶段的一部分,使得无法精确确定北方海侵的持续时间。欧亚大陆东北部沿拉普捷夫海岸和东西伯利亚西部海岸的LIG海相沉积赋存的“缺口”可能与MIS 6冰原外围冰川均衡前隆起的形成和存在以及局部新构造运动有关。

We describe here the vertebrate fauna collected by the West Turkana Paleo Project at Lomekwi, a site best known for yielding the holotype of Kenyanthropus platyops and Lomekwian stone tools, and consisting of several collecting areas providing fossil samples ranging in age from about 3.6 to 2.2 Ma. Analysis of the newly recovered material, alongside a thorough revision of earlier collections, has led to the identification of 85 vertebrate taxa, which provide biochronological indications that help refine the site's chronology and shed light on the paleoenvironmental conditions prevailing during a critical period of early hominin diversification. The newly described fauna illustrates that during the time of Kenyanthropus, hominins shared their landscapes with a rich assemblage of vertebrates, including abundant megaherbivores, some 28 species of artiodactyls, diverse large and medium-size carnivores, and giant crocodiles as apex predators in the lakes and rivers of the Turkana region in the Pliocene. Among primates, the recurring association of Theropithecus with hominins is found at Lomekwi as it is elsewhere. Paleoenvironmental proxies from the Turkana region emphasize the complex and dynamic nature of the habitats that supported this rich biodiversity.
我们在这里描述了由西图尔卡纳古石器项目在洛梅克威收集的脊椎动物群,该遗址以发现肯尼亚猿人platyops和洛梅克威石器的完整模式而闻名,由几个收集区组成,提供的化石样本的年龄从3.6到2.2 Ma不等。对新发现的材料进行分析,并对早期收集的材料进行彻底修订,已经确定了85个脊椎动物分类群,这些分类群提供了生物年代学指标,有助于完善该遗址的年代学,并阐明了早期人类多样化关键时期的古环境条件。新描述的动物群表明,在肯尼亚猿人时代,人类与丰富的脊椎动物群落共享他们的景观,包括大量的巨型食草动物,大约28种偶蹄动物,各种大中型食肉动物,以及上新世图尔卡纳地区湖泊和河流中的巨型食肉动物。在灵长类动物中,像在其他地方一样,在洛梅克威也发现了兽猿与古人类之间反复出现的联系。来自图尔卡纳地区的古环境指标强调了支持这种丰富生物多样性的栖息地的复杂性和动态性质。

The Lateglacial fossil avifauna from Grotta del Romito (Calabria, Southern Italy) and the exploitation of birds by the Upper Paleolithic hunters Grotta del Romito(意大利南部卡拉布里亚)的冰河鸟类化石和旧石器时代晚期猎人对鸟类的利用

Grotta del Romito represents one of the most relevant Upper Palaeolithic sequences of Southern Italy, spanning the end of the Last Glacial Maximum and the Lateglacial (GS1 and GI1) and providing remarkable insights on the Gravettian and Epigravettian lifeways and symbolic behaviours. With this work, we analyse the avian assemblage from Grotta del Romito in order to clarify the dynamics of bird exploitation by the Upper Paleolithic people and assess changes in the paleonvironment due to the Lateglacial climatic shift. Based on the bird species, the surroundings of the cave were characterized by forests alternated with open grasslands, rocky exposures and riverine or marshy habitats. Between unit E and unit D the bird taxa indicate a change from grassland-dominated habitats to forest-dominated habitats, correlated with the beginning of the GI1. The food exploitation of birds, indicated by a number of anthropic modifications, is more intense in the Final Epigravettian and involves Galliformes, Anatidae, Rallidae, Otidiformes, Strigidae, Accipitridae, Falconidae, Corvidae and Passseriformes. The Final Epigravettian hunter-gatherers of Grotta del Romito were also interested in the wings of large Accipitridae (Aquila chrysaetos, cf. Gyps fulvus) for utilitarian purposes or symbolic-mediated behaviour.
Grotta del Romito代表了意大利南部最相关的旧石器时代晚期序列之一,跨越了末次盛冰期和冰河期(GS1和GI1)的末期,并提供了关于格拉韦特人和后格拉韦特人的生活方式和象征性行为的重要见解。通过这项工作,我们分析了Grotta del Romito的鸟类组合,以阐明旧石器时代晚期人类对鸟类的开发动态,并评估由于冰川气候变化而导致的古环境变化。根据鸟类种类,洞穴周围的特征是森林与开阔的草原、岩石暴露和河流或沼泽栖息地交替存在。在单位E和单位D之间,鸟类类群由草地为主生境向森林为主生境转变,与GI1开始相关。鸟类的食物开发在末上移期更为激烈,包括鸡形目、鸭形目、鸟形目、鸟形目、刺形目、刺形目、鹰形目、鸦形目和雀形目。Grotta del Romito的最后的Epigravettian狩猎采集者也对大型阿奎拉科(Aquila chrysaetos,参见Gyps fulvus)的翅膀感兴趣,因为它们具有实用目的或象征媒介行为。

Queen Charlotte Strait (QCSt), along the glacial Pacific margin of Canada, preserves seabed geomorphological records of past tectonic, glacial, and oceanographic processes, particularly since the Last Glacial Maximum. These records can provide an analogue for predicting future seabed and sediment dynamics in contemporary ice-covered region and their surroundings under global warming. The present study identifies and maps the seabed geomorphology and stratigraphy of QCSt by analyzing extensive multibeam bathymetry data, sub-bottom profiles, seafloor images, surface sediments, sediment cores, and 14C dates. The analysis of seabed morphology, erosional and depositional patterns, and sedimentary lithofacies of the late glacial marine geology and postglacial stratigraphy in QCSt collectively allows interpretation of the sequence of processes that formed, shaped, and filled this region. Four primary stratigraphic units were delineated: bedrock, moraines, glaciomarine deposits, and postglacial deposits, along with their seafloor distributions. Seabed features recognized in specific areas include active or relict sand and gravel bedforms, gas masking in thick hemipelagic muds, fan deltas, landslide-gully-fan systems, channels, iceberg lineations, and glass sponge reefs. A series of NNE–SSW-oriented moraines generally indicate ice-sheet retreat eastward toward the Coast Mountains during the last deglaciation, while arcuate moraines northwest of Malcolm Island, curving approximately southward, reflect valley-glacier retreat toward the northern mountains of Vancouver Island. The unconformity atop the glaciomarine deposits, leveled banks, terraces, and other truncated bedforms may indicate past lower sea levels.
夏洛特女王海峡(QCSt)位于加拿大的冰川太平洋边缘,保存着过去的构造、冰川和海洋学过程的海底地貌记录,特别是自末次盛冰期以来。这些记录可以为预测全球变暖下当代冰雪覆盖地区及其周围地区未来的海底和沉积物动态提供模拟。本研究通过分析广泛的多波束测深数据、海底剖面、海底图像、表面沉积物、沉积物岩心和14C年代,确定并绘制了QCSt的海底地貌和地层。通过对QCSt晚冰期海洋地质和冰期后地层的海底形态、侵蚀沉积模式和沉积岩相的分析,可以共同解释该地区形成、塑造和填充的过程序列。划分了四个主要地层单元:基岩、冰碛、冰期海洋沉积物和冰后沉积物,以及它们的海底分布。在特定区域识别的海底特征包括活跃或废弃的砂和砾石床、厚半深海泥浆中的气体掩蔽、扇三角洲、滑坡-沟壑-扇系统、河道、冰山线和玻璃海绵礁。一系列nne - ssw方向的冰碛通常表明在最后一次消冰期,冰盖向东向海岸山脉退缩,而马尔科姆岛西北方向的弧形冰碛大约向南弯曲,反映了温哥华岛北部山脉的山谷冰川退缩。冰川海洋沉积物顶部的不整合,平整的河岸,梯田和其他截断的河床可能表明过去海平面较低。

From lapping waters to marshy lands and back: Quaternary environmental dynamics of the North Caspian inferred from the Raigorod site and contemporary regional correlations 从冲刷水到沼泽地再回来:从Raigorod遗址和当代区域相关性推断的北里海第四纪环境动态

The Caspian Sea underwent a complex series of transgressive and regressive episodes during the Quaternary, with the North Caspian region particularly sensitive to even minor sea-level fluctuations. Outcrops along the Volga River preserve a valuable depositional record of these changes. The Raigorod site, one of the northernmost sections, provides a key stratigraphic archive for reconstructing regional Quaternary environmental changes, but aspects of its stratigraphy, sedimentary architecture, and geochronology have remained uncertain. In this study, using a multi-proxy approach, combining companion borehole data, biolithostratigraphy, geological mapping, and OSL dating, we refined the regional Quaternary framework and clarified several debated regional stratigraphic boundaries. This multidisciplinary approach permitted us to stratify the entire Quaternary interval of the Raigorod site into a series of regional horizons and subhorizons including the Akchagylian, Apsheronian, Tyurkyanian, Bakunian, Khazarian and Khvalynian. Our results show that the Raigorod site evolved from a nearshore setting during the Akchagylian–Apsheronian transgressive phases in the Early Pleistocene to a fluvial regime during the Tyurkyanian regression at the beginning of the Middle Pleistocene. A subsequent Bakunian transgression re-established marine conditions in the study area. The early Khazarian phase is characterized by alternating transgressive and regressive events. Borehole data confirm that Singilian deposits are embedded within the Khazarian sequence, supporting our earlier regional interpretations. The Singilian phase reflects widespread regression and marshland development at the end of the Middle Pleistocene, around MIS 7–6, although OSL dates suggest a younger MIS 5 age. Upper Khazarian deposits reflect stable floodplain conditions driven by local hydrology rather than global climatic forcing. Finally, the overlying Atelian unit, traditionally used as a regional marker, is reinterpreted as periglacial alluvium rather than subaerial loess deposits formed during a major regression, likely associated with MIS 4-3. Our results highlight the value of integrated stratigraphic approaches for regional correlations, while emphasizing limitations in OSL dating in sedimentary settings with complex hydrological and hydrogeological dynamics.
里海在第四纪经历了一系列复杂的海侵和海退事件,北里海地区对即使是很小的海平面波动也特别敏感。伏尔加河沿岸的露头保存了这些变化的宝贵沉积记录。Raigorod遗址是最北端的部分之一,为重建区域第四纪环境变化提供了关键的地层档案,但其地层学,沉积结构和地质年代学方面仍然不确定。在这项研究中,我们使用多代理方法,结合伴随钻孔数据、生物岩石学、地质填图和OSL测年,完善了区域第四纪框架,并澄清了几个有争议的区域地层边界。这种多学科方法使我们能够将Raigorod遗址的整个第四纪区间划分为一系列区域层和亚层,包括Akchagylian, Apsheronian, Tyurkyanian, Bakunian, Khazarian和Khvalynian。结果表明,Raigorod遗址由早更新世akchagyian - apsheronian海侵期的近岸环境演变为中更新世初tyurkyian退行期的河流环境。随后的巴库尼亚海侵恢复了研究地区的海相条件。早期可萨阶段的特点是交替的海侵和退行事件。钻孔数据证实,新加坡的矿床嵌套在可萨层序中,支持了我们之前的区域解释。singlian期反映了中更新世末期(MIS 7-6左右)的大范围退化和沼泽发育,尽管OSL测年表明MIS 5的年龄更小。上可萨矿床反映了由当地水文而非全球气候强迫驱动的稳定洪泛平原条件。最后,上覆的阿特利亚单元,传统上被用作区域标志,被重新解释为冰缘冲积层,而不是在主要回归期间形成的地面黄土沉积物,可能与MIS 4-3有关。我们的研究结果强调了综合地层学方法对区域相关性的价值,同时强调了在具有复杂水文和水文地质动力学的沉积环境中OSL定年的局限性。

The role of climate and eustatic sea-level changes in post-Eemian sedimentary succession in the southern Baltic Sea region 波罗的海南部地区eemian后沉积演替中气候和海平面上升变化的作用

Multiproxy analyses were employed to determine the age and origin of the Pleistocene sedimentary succession at the Kadyny site in the northern part of the Elbląg Heights, northern Poland. Lithofacies analysis yielded the identification of four distinct lithofacies complexes (U1-U4). The units of analysis are fluvial (U1, U3 and U4) and lacustrine-lagoonal sedimentary environments (U2). The formation of the site commenced with the Early Vistulian (units U1, U2 and lower part of U3) and the Lower and Middle Pleniglacial (upper part of unit U3 and unit U4). The sequence of depositional environments was controlled by transgressive-regressive cycles functioning in a glacial-interglacial (main cycle) and stadial-interstadial (secondary cycle) rhythm. The textural characteristics of the sediments and the evolution of vegetation were influenced by climatic factors. The warmest climatic conditions prevailed during the deposition of unit U2 (Odderade Interstadial), which was deposited as a result of fluctuations in the water level in a coastal lake or lagoon separated from the open sea by a sandy spit. The analysed sediments are part of thrust-bounded ridges that form the Elbląg Glacitectonic Complex. These were subsequently thrust-stacked and imbricated, which occurred during the Marine Isotope Stage (MIS) 2 period. This process occurred in two distinct phases: initially from the west, and subsequently from the north. The displacement of the deformed sediments is believed to have taken place over a distance of 10–30 km from the area that is now occupied by the Gulf of Gdańsk.
采用多代理分析方法确定波兰北部Elbląg高地北部Kadyny遗址更新世沉积演替的年龄和起源。岩相分析鉴定出四个不同的岩相复合体(U1-U4)。分析单元为河流环境(U1, U3和U4)和湖-泻湖沉积环境(U2)。遗址的形成始于早维斯陶纪(U1、U2单元和U3单元的下部)和下、中冰期(U3单元和U4单元的上部)。沉积环境序受冰期-间冰期(主旋回)和冰期-间冰期(次旋回)海侵旋回控制。沉积物的结构特征和植被的演变受气候因素的影响。U2单元(Odderade Interstadial)的沉积期间气候条件最温暖,这是由于一个沿海湖泊或泻湖的水位波动而沉积的,该湖泊或泻湖被一个沙嘴与公海隔开。分析的沉积物是冲断边界脊的一部分,形成Elbląg冰川构造复合体。这一过程发生在海洋同位素阶段(MIS) 2时期。这个过程发生在两个不同的阶段:最初从西部开始,随后从北部开始。据信,变形沉积物的位移发生在距离现在被Gdańsk海湾占据的地区10-30公里的地方。
