东晋墓葬制度的考古学分析

东晋墓葬等级制度仅限于高级官员,中下级官员至庶民墓葬等级差异不明显。东晋家族内部墓葬等级差异也不明显,但各家族墓葬的形制和规格似有一定规则,而与家族地位之高低不甚关联。东晋帝王陵墓家族墓葬化,乃当时现实政治之曲折反映。东晋墓葬制度状况与东晋门阀世族社会的现实等级差异不甚相符,此认识对东晋历史研究有一定价值。     

考古发现反映出的成都平原先秦社会经济文化发展

综合分析近数十年来发现的大量考古资料,广泛参证相关文献资料,似乎可以得出这样的认识,在原始社会末期,成都平原的土著先民已经创造出较为发达而具有文明因素的“宝墩村文化”,建立了以渔猎经济为主的父系氏族社会;夏、商至西周,从汉水上游迁徙而来的巴蜀人兴建了虽然仍以渔猎经济为主、但农业经济比重日益增大的古蜀王国,创造出由“三星堆文化”和“十二桥文化”所反映的文明相当发达的“早期蜀文化”;东周时,楚人鳖灵取代蜀王杜宇建立开明王朝,兴农开国而致使蜀国成为以农业经济为主、渔猎经济为辅的富裕国家,致使“晚期蜀文化”成为楚、蜀糅合、多元一体的混融型文化。历秦入汉,基本上华夏化并且体现出华夏文化发展趋向的蜀文化,也就很快消融在汉文化的统一体中了。     

赤藓糖醇在考古木材保护中的应用

选取3种不同遗址出土(出水)的考古木材为试验样品,以赤藓糖醇为定形加固材料,在50℃恒温水浴中以不同质量分数的赤藓糖醇溶液对试验样品进行渗透填充,渗透填充结束后采用真空冷冻干燥方式对试验样品进行脱水干燥。分别从尺寸稳定性、环境稳定性、力学性能、显微形貌几个方面考察了赤藓糖醇对考古木材的定形保护效果。试验结果显示赤藓糖醇作为定形加固材料能够对考古木材起到良好的定形保护作用,定形保护效果随赤藓糖醇质量分数的增加而提升,质量分数为30%赤藓糖醇即可显著提升考古木材的尺寸稳定性、环境稳定性和力学性能。赤藓糖醇以晶体形式在考古木材细胞壁上析出,对木材组织起到支撑和加固作用,提高了考古木材的尺寸稳定性和环境稳定性。     

长沙铜官窑谭家坡遗迹馆内优势病害真菌的分子鉴定

针对长沙铜官窑谭家坡遗迹馆内大肆爆发的微生物病害,为确定造成考古遗迹污染的优势真菌类型,项目组开展了病害真菌的现状调查和快速检测鉴定工作。利用无菌手术刀收集考古遗迹表面典型病害微生物的菌体样品,通过提取样品基因组总DNA、真菌ITS区PCR扩增、构建克隆文库、序列测定和系统发生关系分析等技术完成了病害菌的分子生物学鉴定和类群组成特点分析。结果表明,遗迹馆内考古遗迹表面爆发的主要病害菌为尖孢镰刀菌(Fusarium oxysporum)、白腐菌(Phlebia brevispora)、荷叶离褶伞(Lyophyllum decastes),它们分别隶属于丛赤壳科(Nectriaceae)、伏革菌科(Corticiaceae)、离褶伞科(Lyophyllaceae),均为营腐生真菌,与土壤中木质材料的降解密切相关。考古现场大量的根系残留为病害菌的大肆繁殖提供了重要的营养源,而高的温度和相对湿度是促进病害菌快速生长扩散的主要环境因素。建议人工清除病害菌和根系残留,并对遗迹馆进行适当的环境控制。     

考古发掘现场智能预探测系统的统计与应用

鉴于考古工作中发掘现场情况的不确定性,为改进我国古墓葬遗址等发掘现场的传统探测方法,探讨利用自动化技术,设计开发一套考古发掘现场智能预探测系统,在无考古人员进入墓葬发掘现场的情况下实现预探测功能。该系统主要面向古墓葬遗址的发掘考古需求,由远程监控端、机器人及传输线缆组成。采取分体模块化设计小尺寸机器人,使其可简便拆装成直筒式或车体式两种外形,以适用小直径手工探洞或大直径盗洞两种不同形式的发掘入口。机器人本体集成视频采集及气体传感等环境检测功能模块．实时采集数据并通过传输线缆发送至远程监控端。远程监控端提供窗口化的监控界面软件,该软件在Micro Visual Studio 2005开发平台下完成,在显示并记录采集所得图像和数据的同时,可对机器人的部分模块进行控制。该考古发掘现场智能预探测系统设计制造后在陕西省三个古墓葬遗址进行了实地测试。研究结果显示,数据采集准确及时、视频图像清晰可靠、整体系统运行稳定、可操作性强,基本满足了考古发掘现场的实际需要,推进了考古发掘工作的科技化进程。     

Selected physical parameters to characterize the state of preservation of waterlogged archaeological wood: a practical guide for their determination

Non-destructive and destructive methods for determining the physical parameters of waterlogged wood such as the porosity, the water content, the wet and dry bulk densities plus the density of the cell wall material are presented. Considerations in respect to determination of masses, volumes and sampling size are discussed.     

The emerald and gold necklace from Oplontis,Vesuvian Area,Naples, Italy

The present study refers to the characterization of an emerald and gold necklace, dating from the first century AD, found in Oplontis (Torre Annunziata, Naples, Italy), using non-destructive methodologies such as EPMA and microFTIR. Reference samples, from mines known to be active in the Roman Imperial period, were collected and analyzed using the same techniques. Experimental data were also statistically treated in order to classify the emeralds' mines. The comparison of archaeological and reference data allowed to hypothesize, with high probability, an Egyptian origin for the Oplontis emeralds – even if the Habachtal mine cannot be definitively excluded.

Modelling spatial heterogeneity and nonstationarity in artifact-rich landscapes

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.     

Possible sources of archaeological maize found in Chaco Canyon and Aztec Ruin,New Mexico

Maize played a major role in Chaco's interaction with outlying communities in the southern Colorado Plateau. This paper seeks to determine where archaeological corn cobs brought to Chaco Canyon were grown. Strontium-isotope and trace-metal ratios of 180 soil-water and 18 surface-water sites in the Southern Colorado Plateau have revealed possible source areas for some of 37 archaeological corn cobs from Chaco Canyon and 10 archaeological corn cobs from Aztec Ruin, New Mexico. The most probable source areas for cobs that predate the middle-12th-century drought include several Upper Rio Chaco sites (not including Chaco Canyon). There are many potential source areas for cobs that date to the late A.D. 1100s and early 1200s, all of which lie in the eastern part of the study area. Some Athapascan-age cobs have potential source areas in the Totah, Lobo Mesa, and Dinetah regions. One Gallo Cliff Dwelling cob has a strontium-isotope ratio that exceeds all measured soil-water values. Field sites for this cob may exist in association with Paleozoic and Precambrian rocks found 80–90 km from Chaco Canyon. Potential source areas for most Aztec Ruin cobs (many of which were found in rooms dating to the first half of the 13th-century) appear to be associated with a loess deposit that blankets the Mesa Verde and McElmo Dome regions.
