The widespread occurrence of Celtic field systems in the central part of the Netherlands

The detailed elevation model based on airborne laser altimetry (AHN) proved to be a reliable tool to detect well-developed Celtic field systems, characteristic arable plots of the Iron Age. They were detected in the central part of the Netherlands, where only a limited number of Celtic field systems have been recognized in the past. Most of these previously detected systems were identified in the northern part of the Netherlands or in the southern part, but not in this zone. About 1200 ha of well-developed systems could be identified by AHN in the central part of the Netherlands, of which only 136 ha were registered as an archaeological monument. Another 335 ha of archaeologically identified Celtic field systems were not accepted or recognized by AHN, because they were morphologically less well-developed. Most of the around 1050 ha new discoveries occur in rough vegetations and forested areas, and can hardly be identified with previously used geodetic methods and aerial photography. Less well-developed or preserved systems were even more extensive and remnants were traced as fossil arable layers below plaggen soils or on lower slopes incorporated in mediaeval reclamations. The newly identified Celtic field systems, therefore, can be considered as remnants of much larger areas once covered with these arable plots. In the central part of the Netherlands, the estimated area once covered was at least around 4500 ha, more than enough to supply 10,000 people with cereals. Well-developed Celtic field systems started to develop in the late Iron Age with formation intensifying during the early Roman Period. The central part of the Netherlands is situated just north of the river Rhine, the former boundary of the Roman Empire, the Limes. The newly discovered extent of Celtic field systems will have influenced the interaction between different cultures on the border of the Roman Empire in the early Roman Period, about which very little is known. This perspective underscores the need for an integrated conservation policy and in-depth research through excavations in the near future.     

红山文化研究

红山文化是燕山南北地区新石器时代非常重要的考古学文化,有关红山文化分期的文章已发表多篇,但由于受到当时考古资料所限,学者们分歧较大。本文以近年来所发表的两处层位关系较好的遗存为突破口,尝试对红山文化进行分期,并在分期的基础上,对以往有学者将红山文化划分为不同考古文化类型等问题进行讨论。     

Characterization of dyestuffs in ancient textiles from Xinjiang

Extraordinarily well-preserved organic remains from mortuary and settlement sites, including mummified bodies, are scattered along the outer, oasis-laden rim of the Tarim Basin in Xinjiang Province, China, ranging in date from about 1400 BC to the late first millennium BC. Specimens of textile finds from Chärchän, dated at about 1000 BC were selected for dye analysis using newly developed protocols employing high performance liquid chromatography with spectrophotometric and mass spectrometric detection. A single blue (from an indigo plant), a red (from madder, a Rubia species) and two yellow dyes were detected, although the exact plant source for none of them could be identified with certainty. This research offers new insights in the interpretation of textile finds from prehistoric Xinjiang, and more generally, of early Bronze Age Eurasia.

秦俑二号坑出土一件彩绘跪射俑的保护修复

本研究针对秦俑二号坑出土的一件彩绘跪射俑进行了保护修复,是在考古出土现场保存状况、文物病害及病害机理科学分析的基础上进行的现场保护与实验室保护修复。现场保护重在稳定文物状态和应急处理;实验室保护则依据文物保护程序进行保护修复,在进行文物表面清理工作后,使用AC33(丙烯酸乳液)及PEG200(聚乙二醇)加固彩绘层,使用环氧树脂对陶俑进行了粘接修复,收到了良好的效果。此彩绘陶俑的保护修复工作可为以后大型彩绘文物的保护修复提供参考和借鉴。     

基于环境监测的三星堆遗址祭祀坑考古现场预防性保护

目前考古现场保护主要以应急保护技术与临时加固材料的研究和应用为主,而关于考古现场预防性保护少有报道。本次三星堆遗址祭祀坑发掘保护构建了由考古舱、考古舱环境调控系统、空气质量监测系统、土遗址监测系统、区域气象站、预防性保护措施、监测信息智能管理平台组成的预防性保护体系。发掘前,通过土遗址监测系统和区域气象站获取文物埋藏环境信息和区域气象信息,为考古舱内环境设置提供了依据。发掘过程中,采取舱内温湿度调控、保湿、空气杀菌净化、控制舱内人数与新风换气等预防性保护措施,达到控制考古舱温湿度、减少细菌和真菌总数、降低舱内CO_(2)浓度,减缓象牙等文物失水速度的目的,有效控制了出土文物开裂、酥粉、霉菌暴发等病害发生,为考古发掘与保护赢得了时间。三星堆祭祀坑考古现场预防性保护的创新探索与实践为以后重要遗址的现场保护指引了方向、提供了可借鉴经验。     

Contextualizing Kuruçay Höyük: Assessing the Unexplored Late Chalcolithic Landscape Near the Beginning of Early Social Complexity in SW Turkey

Kuruçay Höyük can be considered a key site for our understanding of Late Prehistory in southwest Turkey and above all, the poorly known Late Chalcolithic (4200–3100 b.c.). Until now, limited research has been conducted on the relationship between the excavated site and its surrounding. This article discusses the Late Chalcolithic results of an integrated survey in the vicinity of Kuruçay Höyük in the Burdur Plain. Drawing upon these results, this paper illustrates that the site was far from an isolated feature during the 4th millennium b.c. The picture that emerges is one of a differentiated settlement system consisting of both larger höyük/tell settlements (like Kuruçay Höyük) and smaller sized, possibly short-lived, flat settlements. These results are further contextualized within the developments that took place in the region during the Chalcolithic, which seem to have opened the door for communities to become more complex during the Early Bronze Age.
