Opacifiers in Late Bronze Age glasses: the use of ToF-SIMS to identify raw ingredients and production techniques

Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is applied to the study of four samples of opaque glass of Late Bronze Age date. The technique is uniquely capable of identifying compositional heterogeneity at a sub-micron resolution within the crystalline opacifiers dispersed through homogeneous glass matrices. It is shown that this provides crucial information on the possible raw ingredients of the opacifying inclusions used, and has the potential for highlighting regional variations in the production technology involved in creating different colours of opaque glass.

Ancient DNA typing shows that a Bronze Age mummy is a composite of different skeletons

Excavations at Cladh Hallan, a Bronze Age-Iron Age settlement on South Uist in the Outer Hebrides off the west coast of Scotland, revealed the skeletons of two adults, a sub-adult and a child buried beneath the foundations of three roundhouses. Osteological and isotopic evidence has shown that the male adult skeleton is a composite made up of parts of at least three different individuals. To test the hypothesis that the female skeleton was also a composite we examined ancient DNA from four of its components: the skull, mandible, right humerus and right femur. Seven polymerase chain reactions (PCRs) were attempted, these covering positions 15,996–16,420, 16–132 and 232–368 of the mitochondrial DNA hypervariable I and II regions. Three PCRs were successful for each sample and a total of 55 sequences were obtained from the cloned products. After exclusion of possible contaminating sequences, the remaining 34 were compared. It was concluded that the mandible, humerus and femur come from different individuals. Insufficient data were obtained to draw conclusions regarding the origin of the skull. The presence of two composite skeletons at Cladh Hallan indicates that the merging of identities may have been a deliberate act, perhaps designed to amalgamate different ancestries into a single lineage.     

Iron and bronze production in Iron Age IIA Philistia: new evidence from Tell es-Safi/Gath, Israel

A metallurgically-oriented excavation in Area A at Tell es-Safi/Gath yielded evidence for iron and bronze production dating to the early Iron Age IIA. Two pit-like features, which differed considerably from one another in colour, texture and content, were excavated. Evidence shows that each feature represents a different in situ activity related to iron production, inferred by the presence of hammerscales, slag prills and slag. An upturned crucible was found on top of one of the features. Analysis of the crucible slag showed that it was used for bronze metallurgy. Tuyères, both round and square in cross-section, were found in and around the two features. The presence of the two industries together presents a unique opportunity to explore the relationship between copper and iron working. This is especially important against the background of the scarcity of evidence for iron production in the Levant during the early phases of the Iron Age.     

An Analysis Of Mitochondrial Dna From The Pakhomovskaya Population Of The Late Bronze Age,Western Siberia

This article presents the results of an analysis of mitochondrial DNA extracted from bone samples from Stary Sad – a burial ground representing the eastern variant of the Late Bronze Age Pakhomovskaya culture in the Baraba forest-steppe, Western Siberia. Comparison with mitochondrial DNA data from earlier populations of the region and also with archaeological facts, points to the origins of the Pakhomovskaya people. Certain components of their gene pool were evidently derived from the local pre-Andronovo populations, others from the actual Andronovo (Fedorovka) population and also from later immigrants. In this article an integrative reconstruction based on biological and cultural facts is proposed.     

韩城出土一件镂空、粉碎性青铜盒修复的实例

2012年5月在上海博物馆展出的"金玉华年—陕西韩城出土周代芮国文物珍品展"陈列陕西省韩城市梁带村两周墓地的考古成果。其中,有一件出土镂空、粉碎性青铜盒,破损非常严重,不成器型,铜胎胎质氧化严重。由于其所具有的艺术和学术价值,急需修复。为此,根据文物自身的特点,用传统修复方法对碎片进行编号、查找拼对、拼接、补缺、篆刻纹饰、打底、作色做旧,并做了临时的框架,在短时间内修复。从修复的结果看,本次修复取得了良好的效果,其修复思路和方法可给同类器物的修复研究工作提供一个借鉴和参考。     

浙江瓯海出土一件西周青铜器腐蚀成因研究

为研究浙江温州瓯海M24墓出土的一件青铜器的腐蚀成因,采用扫描电镜（SEM）、X射线荧光光谱仪（XRF）、X射线衍射仪（XRD）、离子色谱分析仪（HPIC）等,对青铜剑腐蚀产物及其埋藏土壤进行了分析。结果表明,青铜剑已严重腐蚀,铜元素大量流失形成以锡元素为主的腐蚀产物。通过测量模拟瓯海土壤环境下的自腐蚀电位并参照CuH₂O体系的电位-pH图,推导出了浙江瓯海出土一件西周青铜器腐蚀反应历程。研究结果对类似出土文物有参考价值。

Hunter–gatherer foraging ranges, migrations, and travel in the middle Holocene Baikal region of Siberia: Insights from carbon and nitrogen stable isotope signatures

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.
