Biomolecular and micromorphological analysis of suspected faecal deposits at Neolithic Çatalhöyük,Turkey

Suspected coprolites from midden, burial and room fill contexts at Çatalhöyük were analysed by GC/MS and thin section micromorphology. Assessment of sterol biomarkers enabled a distinction between faecal and non-faecal sources for the deposits to be made, with bile acid biomarkers indicating that many of the faecal deposits are human coprolites. The relative lack of ruminant faeces could be due to this material being used as a fuel source. Deposits in burials were observed to contain soil and plant derived sterols rather than their faecal counterparts. Further analysis in thin section enabled identification of associated materials and contents. Diagnostic inclusions such as bone and plant fragments were only present in some of the human coprolites, which were observed to have a very similar morphology to decayed plant remains. This study illustrates the difficulties in distinguishing coprolites in the field and under the microscope, and demonstrates the importance of integrating biogeochemical methods, particularly when such deposits are used as the basis for interpreting human health and diet, and use-of-space in settlements.     

Tongan and Samoan volcanic glass: pXRF analysis and implications for constructs of ancestral Polynesian society

A provenance study of volcanic glass specimens from 12 archaeological sites in the Kingdom of Tonga is carried out employing pXRF (portable X-ray fluorescence) analysis. To accomplish this, volcanic glass samples from previously identified sources in northern Tonga and the adjacent islands of Samoa are analyzed. Results indicate inter-island voyaging and interaction over a 600 km linear distance along the Tongan island chain from first Lapita settlement ca 2900 BP throughout later prehistory. Tongan volcanic glass, however, is not found in Samoa and, with the exception of one late prehistoric specimen, Samoan volcanic glass is not present in Tonga. This distribution challenges current concepts of an integrated ancestral society and homeland common to Tonga and Samoa from the Lapita period onward.     

A chronometric tool for Hawaiian archaeology: the hydration dating of Pu'u Wa'awa'a trachytic glass

The Pu'u Wa'awa'a trachytic glass deposit located on the Big Island of Hawai'i was a source of lithic tools for much of Hawaiian prehistory. Routinely encountered at habitation sites, the glass has the potential to provide absolute dates based upon the degree of surface hydration. Infrared photoacoustic spectroscopy and secondary ion mass spectrometry were used to monitor the diffusion of water in archaeological and experimental samples. Accelerated laboratory hydration experiments show that water diffusion in trachytic glass containing a structural water content of 0.16% ± 0.03% is linear with time. Application of the calibration to trachytic glass artifacts from the Kahalu'u habitation cave have produced chronometric dates in the 17th–18th centuries. These age estimates are in agreement with radiocarbon dates and artifactual data that bracket the site occupation. However, the glass dates do not correlate well with site stratigraphy and this suggests that slight sample imperfections that retain water may be one factor that results in ages that are too early for later occupation levels.     

Interpreting elements and isotopes in glass: A review

Substantial databases of elemental and isotopic analyses of ancient glass exist and are used to investigate raw material origin, trade, exchange, and processes such as mixing and recycling. However, the chemistry of archaeological glass may be challenging to the untrained. The paper provides structured information on the origin of chemical elements and their isotopes in ancient glass. It details some of the functions of individual elements in the glass and from which raw material(s) or process(es) they originate.     

中国史前玉文化板块论

中国史前玉器有着长达6000余年的历史,遍布东、北、西、南各地,组成相对独立发展的群体及其玉文化区域。其历经玉兵器、玉美器、玉神器以及早期“王室玉”等若干阶段的演进和积淀,为华夏文明的创造奠基了第一块坚实的基石。本文采纳地质学上的“板块”一词以概括说明史前玉文化的宏观性质及其微观特点,史前玉文化板块分为东夷玉文化板块、淮夷玉文化板块、古越玉文化板块等三大玉板块以及海岱玉文化东夷亚板块、陶寺玉文化华夏亚板块、石峁玉文化鬼国亚板块、齐家玉文化氐羌亚板块和石家河玉文化荆蛮亚板块等五个文化亚板块。它们按自身规律运动又互为碰撞、渗透、并存以至融合,终于走向其归宿,熔铸为统一的中华玉文化。     

Chemical analyses of organic residues in archaeological pottery from Arbon Bleiche 3, Switzerland – evidence for dairying in the late Neolithic

Fatty acids distribution and stable isotope ratios (bulk δ¹³C, δ¹⁵N and δ¹³C of individual fatty acids) of organic residues from 30 potsherds have been used to get further insights into the diet at the Late Neolithic (3384–3370 BC) site of Arbon Bleiche 3, Switzerland. The results are compared with modern equivalents of animal and vegetable fats, which may have been consumed in a mixed ecology community having agrarian, breeding, shepherd, gathering, hunting, and fishing activities. The used combined chemical and isotopic approach provides valuable information to complement archaeological indirect evidence about the dietary trends obtained from the analysis of faunal and plant remains. The small variations of the δ¹³C and δ¹⁵N values within the range expected for degraded animal and plant tissues, is consistent with the archaeological evidence of animals, whose subsistence was mainly based on C₃ plants. The overall fatty acid composition and the stable carbon isotopic compositions of palmitic, stearic and oleic acids of the organic residues indicate that the studied Arbon Bleiche 3 sherds contain fat residues of plant and animal origin, most likely ruminant (bovine and ovine). In several vessels the presence of milk residues provides direct evidence for dairying during the late Neolithic in central Europe.

饱水平整漆膜保护方法在风篷岭汉墓出土漆器中的应用

漆器是研究古文化的实物资料,多有精美纹饰和铭文,但考古发掘出土的漆器多有饱水、糟朽和变形等病害,甚至胎体完全腐蚀,仅剩漆膜,且无法复原。在研究前人对漆膜保护的基础上,提出一种平整漆膜的保护方法,整形脱水后以棉纸为背衬、虫胶漆为粘接剂粘接漆膜,再用镶嵌磁铁的有机玻璃板夹住固定。成功保护了长沙风篷岭汉墓出土的60余件漆膜,为今后研究漆膜的保护修复方法提供参考作用。
