Clay plates with stylized representations of birds found at Section VI of the Gorbunovo Peat Bog (Trans-Urals) in 1926 and 2009 are described here with regard to technology, typology, function, and age. Similarities with Suzgun and Late Cherkaskul artifacts (13th – 12th centuries BC) point to the date of the plates. Suzgun sanctuaries and Andronovo burial sites suggest that the site with which the plates are associated might be either ritual or memorial. 相似文献

2007年6—7月,在位于西安市长安县北里王村村东的上洛县主墓中,出土了一批色彩鲜艳的彩绘木俑。因该墓葬曾遭受早期盗扰,出土时木俑较为凌乱摆放在墓室前厅,原来的摆放位置已被扰乱。出土的彩绘木俑均有不同程度的腐朽,其中部分彩绘木俑保存较完整,部分有残缺;整体彩绘保存相对完整,局部有脱落现象。由于长期遭受墓葬环境的影响,所有的彩绘木俑出土时都处于亚饱水状态,而且机械强度较低,没有彩绘或彩绘脱落部位的木胎外观变黄、变脆。这批木俑的木俑颜色鲜艳、姿态各异,不仅具有较高的艺术价值,而且对研究明代民间的宗教信仰,以及葬丧习俗也颇有裨益。为了保护这批珍贵的文物,通过对比试验研究,采用自然脱水法使其脱水定形。使用3%PrimalAC33的水溶液对其彩绘层进行加固保护。同时,在保护处理的过程中,通过显微观察以及一些科学分析手段,对这批木俑的制作方法、装饰材料及工艺进行了初步的探索与研究。 相似文献

出土、出水饱水木质文物冷冻干燥研究进展 总被引:1,自引:0,他引:1
冷冻干燥是稳定出土、出水饱水木质文物的主要方法之一。该方法基于水由固态直接成为气态的升华过程不产生表面张力的原理,可避免饱水木材脱水时受到干燥应力的破坏。数十年来,经过实验实践和不断完善,冷冻干燥在出土、出水降解木材的稳定中取得了很好的效果,在大型、厚重木质文物的保护方面得到成功应用。本研究基于在出土、出水含盐饱水木质文物保护方面的多年实践,对国内外在脱盐、抗菌、热浸、预冻和升华干燥工艺等方面的进展进行了回顾,并提出了解决一些现有问题的技术设想。 相似文献

ABSTRACTThe US Middle Atlantic region, known for its rich archaeological record and diverse topographic settings, is experiencing a range of climate change impacts, most notably: sea level rise and coastal erosion in its tidal zones. Documented palaeostratigraphic and palynological studies throughout the region provide a record of late Pleistocene/Holocene environmental response to changing climate, confirming observations from other disciplines that the magnitude of modern impacts exceeds past temporal and spatial patterns. The corresponding impact on archaeological resources is great, requiring a renewed effort to document threatened sites while also working with local and state governments to develop mitigation strategies. The Middle Atlantic Archaeological Conference (MAAC) created the Sea Level Rise and Storm Surge Committee to promote regional partnerships in site impact assessment and mitigation strategies. The network highlights the predicament of archaeology in this time of climate change: accelerated research and discovery in the face of catastrophic loss. 相似文献

丙烯酸非水分散体等几种土遗址防风化加固剂的效果比较 总被引:11,自引:3,他引:11
对丙烯酸树脂非水分散体等几种土遗址防风化加固剂进行了加固效果对比检验,包括加固前后土样各种性能的变化,如:重量、颜色、孔隙率变化,抗压强度的提高,耐水、耐冻融、耐盐能力的增加等。通过检验发现,在所试材料中丙烯酸树脂非水分散体加固刑在浓度非常低的情况下对土体就有加固作用,使土体具有很好的耐水性、耐冻触能力,耐盐破坏能力也有提高,并且不影响土体的外观和透气性。而其它材料如正硅酸乙酯、丙烯酸树脂、聚氨酯、聚酯等虽在一些性能上能满足需要,但还有一些方面不能满足要求。对比表明,丙烯酸非水分散体是一类优良的土遗址防风化加固剂。 相似文献

Recent fieldwork on the south coast of the island of Socotra, Yemen, has revealed a hitherto unknown petroglyph site. This site represents the first rock art to have been recorded on the south coast, an area generally regarded as being unpopulated up until the recent past. The corpus of recorded petroglyphs includes feet, cupules, anthropomorphic figures and geometric motifs, whose designs parallel those from known rock‐art sites on the north coast. The importance of this site is that it provides us with the first glimpse into the religious and socio‐political lives of the inhabitants of the previously unknown southern half of Socotra. Placing these petroglyphs within the broader context of rock‐art studies on the island of Socotra has also allowed us to begin to disentangle the skewed view of Socotra's inhabitants. 相似文献

南越国宫署遗址为大型土遗址类型,1996年11月国务院公布为全国重点文物保护单位,由于挖掘时间较长,遗址场地条件有限,已经出现了不同程度的风化、粉化、开裂、局部坍塌等严重病害。为此本课题组经过前期分析测试研究,采用有机硅改性丙烯酸、PS材料、有机硅改性硅酸盐、硅酸酯类和无机-有机复合材料等几种常用土遗址防风化加固材料,对南越国宫署土遗址样块进行了加固效果对比测试,研究了加固前后土样各种性能的变化情况。研究发现:硅酸酯类和无机-有机复合材料加固土体具有很好的耐水性,耐盐破坏能力,抗压强度也有提高,并且不影响土体的外观和透气性;PS材料加固土体后透气性和渗透性虽好,但耐水性能较差,加固强度低,而且容易泛白;有机硅改性丙烯酸和有机硅改性硅酸盐材料加固后土样强度适中,但透气性、耐盐性和耐水性较差。可以看出硅酸酯类和无机-有机复合材料加固南越国宫署土样的效果较好,建议可进入现场试验评估阶段。 相似文献

AbstractThe paper presents the results of the restoration and conservation work which has been carried out in three archaeological areas in the Autonomous Province of Trento. The areas, which have been opened to the public for more than ten years, are the open-air archaeological site of Monte S. Martino, Roman Tridentum (an underground site under the historical city centre of Trento), and Fiavé (a pile dwelling site in a peat bog). These areas present very different environmental characteristics and have therefore required different interventions according to their speci?c situation.In order to reduce maintenance and extraordinary costs, appropriate conservation of the archaeological remains is required. This consists of methodologies of conservation according to the characteristics of the environment; continuous monitoring systems and indirect preventive intervention; and annual maintenance planning. 相似文献

AbstractThis paper will outline the approach taken for monitoring of two waterlogged areas in England: the multi-period deposits beneath the historic town of Nantwich, Cheshire, and the Bronze Age timber platform at Whittlesey, Cambridgeshire. These two examples allow contrast and comparison between urban and rural contexts, and between multiple ownerships and single development. The projects also illustrate how English planning guidance can be variously interpreted dependent on conflicting aims and objectives. The paper will describe the characteristics of the sites, their past history and present threats, and the suggested management strategies for each. The duration, spatial interval, and methods of monitoring (including use of in situ redox probes, Time Domain Reflectometry, sediment geochemistry, and water-level measurement) will be discussed, and how short-term data-gathering is actually what influences decision-making. 相似文献

非水分散体加固剂固结砂土能力的研究 总被引:4,自引:1,他引:3
有机树脂非水分散体是一种新的土体防风化加固材料,对黄土样品和考古遗址都有好的加固效果。为检验这种加固剂对不同土体的加固能力,选择砂土作为被加固材料,用1.5%TD和2%21J加固剂进行加固试验。结果表明这种材料以低的浓度就有好的加固效果,经过加固的砂土样颜色和孔隙率变化小,土样的力学强度得到提高,具有好的耐水耐冻融能力及较好的耐盐能力,证明这种材料可用于砂土质遗址的加固保护。 相似文献

Two ancient wooden anchors with ropes, dating to different periods, were found on the western shore of the Dead Sea. The one-armed anchor was dated by 14C to the Late Iron Age—Persian Period, and the second anchor to the Roman Period. The saline water of the Dead Sea preserved the wood and ropes, but corroded almost all the metal parts. A thin black crust of lead and a green crust of copper are the only remains of the collar of the Roman anchor. The finds were made from local tree species and were probably made locally: the one-armed anchor from Acacia, the Roman one from Christ-thorn, and both ropes of date-palm.

The condition of a wooden shipwreck varies considerably according to the nature of the site environment. Each marine site exhibits a unique biodeteriogenic potential influenced by prevailing hydrographic factors. The potential rate of degradation of organic archaeological material can be determined by monitoring the diversity and activity of marine organisms and is important in determining if in situ protection is required. To illustrate the deteriogenic potential of marine archaeological sites a cold water site (Langstone Harbour, UK) was compared with a warm water site (Zakynthos, Greece). The warm water site supported a greater diversity and activity of wood-boring crustaceans and molluscs than the cold water site. However, although the mycodiversity at the two sites was different the deteriogenic potential was similar. These results indicated that warm water sites are more hazardous and in situ protection is required during and after excavation. 相似文献

为研究潮湿环境土遗址加固效果评估方法,在杭州地区进行现场模拟探方加固实验,并对加固后坑壁的波速、含水率、相对水平位移进行监测,对加固的模拟探方稳定性做出评估,以望通过采用科学定量手段评价土遗址夯筑支顶加固效果,为土遗址夯筑支顶加固效果评估提供参考。试验结果表明:模拟探方坑壁表层含水率随深度的增加而升高,含水率变化量逐渐减小;加固后坑壁土体初始强度随深度的增加而提高,且后期硬化过程也较上部区域快,土体强度随时间在逐渐增加;夯筑后坑壁前四五天位移值逐渐增大,且位移值随深度的增加而升高,后期趋于稳定。研究表明,基于变形监测技术评估夯筑体整体稳定性科学合理,基于表层含水量和波速变化评估夯筑土体强度变化是较好的手段。评估结果可为其他潮湿地区土遗址夯筑加固效果评估方法提供参考。 相似文献

AbstractDuring the four seasons of excavations of the Roman town of Iovia-Botivo (present-day Ludbreg, Croatia), a smaller bath and sizeable (presumably public) building were discovered. An optimal plan for presentation was made with all due consideration for the site’s speci?c situation. The plan encompassed scholarly and professional requirements concerning conservation in situ combined with the needs of successful cultural management, thus resulting in alignment between the latter two factors as well as cost effectiveness. By applying the aforementioned principles (which served more as guidelines rather than rigid edicts) and facilitating successful, interdisciplinary cooperation between the national government, the municipal authorities, and researchers, it was possible to provide a sound, legally secure future for this site. 相似文献
