Technological examination of Neolithic-Bronze Age pottery from central and southeast Europe and from the Near East

Scanning electron microscopy is used to examine sequences of pottery sherds from central and southeast Europe, Greece and the Near East spanning the period from the Neolithic to the Bronze Age, in order to obtain information on the ceramic technologies employed in antiquity. On the basis of the vitrification observed and the chemical composition, the types of clay and firing procedures (temperature and atmosphere) employed in the manufacture of the pottery are defined. Two under-lying trends in the associated ceramic technologies are thus identified. The first is based on the use of non-calcareous or “unstable” calcareous clays fired in a reducing atmosphere at temperatures below 800 °C and the second on the use of “stable” calcareous clays fired in an oxidizing atmosphere at temperatures in excess of 800 °C.     

Diet Variability and Stable Isotope Analyses: Looking for Variables Within the Late Neolithic and Iron Age Human Groups from Gougenheim Site and Surrounding Areas (Alsace,France)

Several human groups (from the Neolithic to the Bronze Age) have been analysed in France during the past decade (mainly for C and N stable isotope) as part of research programmes focusing on prehistoric dietary variability. The environment, cultural/social choices or even biological characteristics are among the parameters influencing food acquisition and consumption. This short report presents the first diachronic isotopic results on the palaeodiet in northeastern France. Because of the exceptional archaeological characteristics (human deposits in various positions in pits) of the bone collection from the site of Gougenheim and the surrounding areas (Late Neolithic‐Iron Age, Alsace, France), this assemblage provides a new isotopic dataset to study diet and the potential relationship with social elements or other factors involved in food choices. In order to obtain individual palaeodietary information, carbon and nitrogen stable isotope analyses were performed on 23 adults and 20 immature human bone collagen samples as well as on 25 animal remains. Data were then combined with zooarchaeological and anthropological/archaeological results to reconstruct part of the dietary pattern (i.e. protein consumed) and to detect possible links between the deposit and individual or group social status, defined here by specific mortuary practices. For the Late Neolithic period, isotopic values show, among other things, a wide δ¹³C range within the female human group, which is statistically lower than the male one. Women probably consumed more diversified food sources, suggesting increased residential mobility. Although body deposits point to the presence of two distinct subgroups, no relationship with animal protein intake was identified. Moreover, the comparison with Iron Age individuals brought to light different dietary patterns between the two periods, indicating that stable isotope values were affected throughout time either by increased millet/legume consumption or environmental/anthropic changes.

Lead isotope and metal source of Shang bronzes: a response to Sun et al.’s comments

In this brief response to Sun et al.’s ( 2018 ) comments on our paper, we re‐emphasize that archaeological, chemical and isotopic evidence are all relevant to the discussion about the metal source of the Shang period with highly radiogenic lead isotope ratios. The southern African bronzes have much lower lead contents and quite different lead isotopic signatures than the Shang bronzes. More importantly, there was no metallurgy of any kind in southern Africa before c.200 ce , so southern Africa cannot possibly be the source of Shang bronze, which date to about 1500 to 1000 bce .     

Thirty‐Four Years of Stable Isotopic Analyses of Ancient Skeletons in China: an Overview,Progress and Prospects

Stable isotope analysis of ancient skeletons has become a routine method and widely used to answer diverse archaeological questions related to the human (animal) diets since the initial study in 1977. However, this study in china is underestimated and much less unknown to international circles considering the infrequent publications in English journals. In this review paper, the research history in China was overviewed shortly and then, the research progresses concerning different research themes, such as the chronological trajectory of human diets, the development and spread of agriculture, the mechanism of animal domestication, human social hierarchy, and so on, were introduced in detail, trying to draw a rough framework of human dietary evolution given the unique Chinese geography and cultures. At last, the potential research directions were also suggested for the future studies.     

The spatial dimension of the woodland period

ABSTRACT

State archaeological site files are a critical component of cultural resource management and information management toolkits. Yet, engagement with these datasets for research purposes can be difficult, at best. We address some of the challenges to a synthesis of spatial data from state site files by examining the Woodland period components of Deptford/Cartersville, Swift Creek, and Weeden Island. We also examine time slices of a large set of radiocarbon dates from contexts reported to be associated with Deptford and Swift Creek. Dates are plotted on a map at the same spatial scale as our site files dataset to evaluate time and space simultaneously. This study reveals important gaps in the radiocarbon dataset that can be rectified with strategic sampling. It also supports some long-held ideas about the spatial distribution of Deptford, Swift Creek, and Weeden Island. For example, Weeden Island is demonstrated to be strongly centered on the Alabama and Florida Gulf Coast, whereas Deptford is concentrated on both the Gulf and the Atlantic Coastal Plains.     

Evaluation of Quantitative XRF Analysis Applied to Determine Cobalt Sources in Chinese Blue‐and‐White Porcelain

A method using the ratios between MnO, Fe₂O₃ and CoO to differentiate the cobalt sources for Chinese blue‐and‐white porcelain was developed in Oxford in the 1950s using X‐ray fluorescence (XRF) analysis directly on the glaze. In this paper, six blue‐and‐white porcelain sherds from the Luomaqiao kiln were analysed by XRF on the glaze and by scanning electron microscopy with energy‐dispersive spectrometry (SEM‐EDS) in cross‐section. The ratios between MnO, Fe₂O₃ and CoO calculated by quantitative XRF and EDS analyses are different. The analysis depths for MnO, Fe₂O₃ and CoO are < 60 μm by XRF analysis. However, the average glaze thickness of samples is > 400 μm, and the MnO, Fe₂O₃ and CoO mainly remain in the lower layer of the glaze, which is beyond the analysis depths of XRF analysis. The limitations of major and minor quantitative analyses for differentiating cobalt sources are discussed.     

Complex raw materials and the supply system: Mineralogical and geochemical study of the jade artefacts of the Longshan Culture (2400–2000 bce) from Sujiacun site in coastal Shandong,China

X‐ray fluorescence (XRF), X‐ray diffraction (XRD) and Raman spectroscopy were employed to analyse the chemical compositions and phase structures of nine pieces of jade artefacts unearthed from Sujiacun, a Longshan Culture (2400–2000 bce ) site in coastal Shandong, eastern China. The results of the analyses indicated these samples were primarily made from multiple raw mineral materials, including antigorite, actinolite, clinochlore, turquoise and muscovite. No nephrite was recovered from the Sujiacun site. This is strikingly different from other top‐ranking settlements of Longshan Culture, such as Dantu, Liangchengzhen and Xizhufeng, in which nephrite was the main material of jade artefacts. This may reflect the distinctions in the supply system of jade raw materials among different rankings of Longshan period sites. In addition, laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS) was used to analyse the composition of the rare earth elements of serpentine jade. These preliminary results were compared with published data on the composition of serpentine jade and it was found that the Sujiacun serpentine jade artefacts were likely sourced from the Taishan jade deposit.     

Assessment of risks on a territorial scale for archaeological sites in İzmir

This article focuses on natural, institutional, and human factors threatening archaeological sites. A methodology is developed for assessing risks to multiple assets on a territorial scale. The methodology consists of hazard assessment, vulnerability assessment, and risk assessment. Hazard assessment involves identifying hazard exposure areas and measuring the frequency and intensity of each hazard. Vulnerability assessment incorporates examining physical, managerial, and contextual vulnerabilities of structures and remains. Geographical information systems are utilised for producing hazard, vulnerability, and risk maps. An overall picture of risks for an entire territory allows decision-makers to make informed decisions at an upstream level to limit further degradation and ensure the preservation of archaeological assets. The methodology was tested by conducting a comprehensive study in ?zmir (Turkey), where 229 archaeological sites located in 21 metropolitan districts were studied. The proposed approach provides the promise of applicability across a range of historic environments.     

The place of immigration in studies of geography and race

This paper argues that geographical research on immigration and geographical research on race and racism in the USA must be explicitly connected. Geographic processes such as globalization and urban development already link immigration with race and racism and suggest a need to conceptualize research agendas around immigration and race in relation to each other. Not only are racialized groups spatially connected in many neighbourhoods, cities and regions of the USA, but they are also linked through policies structured by the state at various scales and narratives produced about subordinated and racialized groups. In making this argument, I attempt to highlight work in geography, in related social sciences and in ethnic studies that demonstrates the necessity and usefulness of this approach. Geographers are uniquely positioned to illuminate how the construction of space, place and scale overlaps with the construction of racial-ethnic and immigrant identities and with racism itself. The paper argues that these and other research questions also benefit from linking race and immigration to gender, as some feminist geography and feminist studies have done. Likewise, ethnic studies offer a wealth of theoretical, methodological and empirical insight into linking immigration, race and racism in geographical work.
