Kiacatoo Man, a large, rugged Aboriginal adult buried in the Lachlan riverine plains of southeastern Australia, was discovered in 2011. Laser‐ablation uranium series analysis on bone yielded a minimum age for the burial of 27.4 ± 0.4 ka (2σ). Single‐grain, optically stimulated luminescence ages on quartz sediment in which the grave had been dug gave a weighted mean age of 26.4 ± 1.5 ka (1σ). Luminescence samples from the grave infill and from sediment beneath the grave exhibit overdispersed dose distributions consistent with bioturbation or other disturbance, which has obscured the burial signal. The overlap between the minimum (U‐series) and maximum (luminescence) ages places the burial between 27.0 and 29.4 ka (2σ). Luminescence ages obtained from the channel belt of between 28 ± 2 and 25 ± 3 ka indicate that fluvial sedimentation was occurring before the Last Glacial Maximum, which is consistent with the broader geomorphic setting. Together, these results are internally and regionally consistent, and indicate that Kiacatoo Man was one of the more ancient individuals so far identified in Australia. His remains are important to our understanding of patterns of biological variation and other processes that have shaped people in the Murray‐Darling Basin through time.

The middle pleistocene deposits of Waverley Wood Pit,Warwickshire, England

A complex of channels underlying the Baginton-Lillington Gravel (Baginton Formation) at Waverley Wood Quarry, Warwickshire is described. Fossil pollen and plant macrofossils, Coleoptera, Ostracoda, Mollusca and Mammalia are described from the channel-fill deposits. Consideration of all the evidence allows the identification of four separate stages of channel fill which largely occurred under a cool temperate climate. At the top of Channel 2 evidence for a cold, continental climatic episode can be recognised, suggesting that the whole complex was deposited under a fluctuating climate at the end of a temperate stage. At two levels in the channels human artefacts were recovered confirming the presence of Palaeolithic people in Warwickshire during the deposition of the sediments. Amino-acid geochronology suggests an age within the ‘Cromerian Complex’ Stage for the channels. The small vertebrate and molluscan faunas indicate that the deposits are no older than the latter part of the ‘Cromerian Complex’ Stage of East Anglia. The regional stratigraphic significance of the Waverley Wood succession is outlined.  相似文献   

Imaging of Buried Archaeological Materials: The Reflection Properties of Archaeological Wood   总被引：1，自引：0，他引：1

Effective marine archaeological site management demands detailed information on not only the spatial distribution of artefacts but also the degradation state of the materials present. Although sonar methods have frequently been used in an attempt to detect buried wooden shipwrecks they are currently unable to indicate their degradation state. To assess the sensitivity of acoustic measurements to changes in the degradation state of such material, and hence the potential for sonars to quantify degradation, laboratory measurements of compressional wave velocity, as well as bulk density for oak and pine samples, in varying states of decay, were undertaken. These data enabled the calculation of theoretical reflection coefficients for such materials buried in various marine sediments. As wood degrades, the reflection coefficients become more negative, resulting in the hypothesis that the more degraded wood becomes, the easier it should be to detect. Typical reflection coefficients of the order of −0.43 and −0.52 for the most degraded oak and pine samples in sand are predicted. Conversely, for wood exposed to seawater the predicted reflection coefficients are large and positive for undegraded material (0.35 for oak, 0.18 for pine) and decrease to zero or slightly below for the most degraded samples. This indicates that exposed timbers, when heavily degraded, can be acoustically transparent and so undetectable by acoustic methods. Corroboration of these experimental results was provided through comparison with high resolution seismic reflection data that has been acquired over two shipwrecks.  相似文献   

Progress in Environmental Evolvement and Environmental Archaeology Study in the Yangtze Delta （China）     

CHEN Lei 《地球空间信息科学学报》2008,11(3):228-234

A review was conducted on the environmental evolvement and environmental archaeological research since the 1980s in the Yangtze Delta. Former environmental evolvement and environmental archaeological research results can be summed up into 4 aspects： 1） Formation and evolution of the Taihu Lake; 2） Transgression and sea-level changes in the Holocene epoch; 3） Reconstruction of the pre-historical environment; and 4） Impacts of environmental variations on the rise and fall of human civilization （formation of the cultural interruptions）. Based on this review, some limitations in the present research methods and possible outcomes are pointed out in this paper.  相似文献   

湖北辽瓦店遗址地层记录的环境变迁与人类活动的关系研究   总被引：6，自引：4，他引：2       下载免费PDF全文

用XRF和ICP-AES方法分别测试了湖北辽瓦店遗址地层样品的氧化物含量和地球化学元素含量,恢复了遗址地层中夏代文化层、东周文化层和明清文化层记录的环境变化和人类活动特征。结果表明:1)夏代文化层时期,气候温暖湿润,生态环境良好,人类活动与自然环境和谐度高,有原始的手工业活动记录。2)东周时期气候开始进入干旱期,干旱程度在上东周文化层中部逐渐加深(LOI=6.98%),到了上东周文化层顶部气候进入暖湿期。该层Cu含量的异常高值(0.31mg/g)和出土的青铜器表明本文化层反映了青铜社会的繁荣期,而P含量的高值(22.73mg/g)和动物骨屑则反映了该期人们驯养、捕猎动物的普遍性。3)明清时期的气候趋于干凉,明代文化层中部有短暂暖湿期,后又进入冷干期。清代文化层中下部有暖湿特征,之后重新进入干冷期。该层Ca(均值101.5mg/g),Mg(均值60.27mg/g),Zn和Pb的高含量表明遗址曾有过制陶(瓷)业的历史。另外,Mg和Ca含量的高值与耕作区、墙壁灰浆、生活垃圾堆积等人类活动相关。Ca和Mg含量在近现代层逐步升高揭示了人类活动逐渐增强的事实。地层的平均粒径自上东周文化层(<142cm)开始出现振荡,暗示汉江洪水和季节性山洪发生的频率不断增加,表明恶劣环境条件虽然促进了人类生产力水平的提高,但原始生态系统却遭到破坏,人类活动对自然环境的正反馈效应日益凸显。  相似文献

长江三角洲长江以北地区全新世以来人地关系的环境考古研究   总被引：14，自引：10，他引：14

通过长江三角洲长江以北地区高邮龙虬庄和海安青墩两个新石器时代考古遗址剖面粒度、磁化率、孢粉以及年代学测定，较为全面地分析了该区全新世以来生态环境变化与人类文明兴衰的相互关系，研究结果表明：在有人类活动以前，该区距离海洋较远，但受海面变化影响强烈。此后，气候向暖湿方向发展，7000—6000间的大西洋温暖湿润气候以及3700aB．P．左右期间，该区气候适宜，人类文明在这样的适宜气侯条件下得到长足发展。值得注意的是，海安青墩遗址剖面中出现厚达1m多的自然沉积地层，粒度分析以及孢粉分析表明，这一自然沉积地层是4000aB．P．以来的海侵事件所致，正是这次海侵事件，使研究区人类文明得以衰落。  相似文献
