Neutron activation analysis of fine grey pottery from Conimbriga,Santa Olaia and Tavarede,Portugal

The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga.     

Archaeometric analysis of ceramic production in Tiwanaku state (c.500–1000 ce): An exploratory study

The chemical and mineralogical characterization of seven ceramic fragments produced within Tiwanaku state (c.500–1000 ce ) is reported. The instrumental techniques used included X‐ray elemental and mineralogical chemical analysis, Raman spectroscopy, and scanning and light microscopy. The results indicate there are several clay types, although they show similarities, such as the use of a plant‐based temper. The red colour of the decoration is hematite, and manganese oxides such as jacobsite are present in the black. The white colour is a mixture of gypsum and clay, and the orange is a mixture of hematite and clay. The use of colours, the quality of the clays and the temperatures reached during pottery firing point to expertise in ceramic production and to complex decision‐making processes. The multi‐elemental archaeometric approach documented here could become an important tool to shed a light on ancient ceramic technology and the internal variance of Tiwanaku pottery.     

Geochemical evidence for the manufacture,logistics and supply‐chain management of Emperor Qin Shihuang's Terracotta Army,China

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .     

Change and Inertia on the Frontier: Archaeology at the Paraje de San Diego, Camino Real, in Southern New Mexico

Archaeological testing was conducted at the Paraje de San Diego, a late sixteenth- through nineteenth-century camp site on the Camino Real 30 mi north of Las Cruces. The site is well preserved, though the site structure is complex, reflecting repeated, short-term occupation. The archaeological record (especially the many, diverse ceramics to be recovered) reflects certain changing conditions in southern New Mexico and elsewhere over time. However, the record also indicates a pervasive resistance to development. This resistance, which might be a widespread frontier phenomenon, is called structural interia.     

Cohabitants,Captives, or Trade: The Early Late Woodland Non-Weaver Ceramic Assemblage at the Marseton #2 Weaver Village in Mercer County,Illinois

The Marseton #2 site is a Weaver ring midden in the Mississippi Valley of Mercer County, Illinois, that was buried by a catastrophic flood event a few centuries after the site had been abandoned. Analysis of the more than 740,000 ceramic items from the village provides insights as to Weaver interactions with other non-Weaver early Late Woodland groups of the region. While the presence of non-Weaver ceramics at the village might represent trade items, or vessels manufactured by potters peacefully or forcibly brought to the site, it is suggested that a non-Weaver household producing Levsen-like ceramics was coexisting at Marseton #2 alongside multiple Weaver households.     

从“良渚全考古”到“良博全展示”——以良渚博物院2018年改陈策展为例

良渚考古工作历经八十余年,考古内涵不断丰富,考古价值不断提升,已进入到"良渚全考古"时代,是边发现、边研究、边保护、边利用、边传承的模式。2018年良渚博物院改陈,进入"良博全展示"阶段。现有的展览全面展示良渚考古成果,全面呈现良渚文化内涵,全面阐释良渚文明价值,全面解读良渚遗存信息。良渚的展示除了依靠文物本身或图文所呈现和传递的信息,还采用过程性展示、功能性展示、复原性展示、对比性展示、演变性展示、场景性展示等多种手段,多角度、全方位地解读和展示遗物,力图将良渚文物的故事讲清楚、讲明白。     

Linking Heritage Preservation and Community Development: An Assessment of Grassroots Heritage Based Projects as Vehicles for Socio-Economic Development and Sustainable Heritage Preservation in Zimbabwe

This paper engages the practical aspects of linking heritage, in particular, archaeological heritage, with both individual and community economic development. In recent years, there has been growing realisation that culture, inclusive of cultural heritage, can be both a driver and an enabler of economic development, especially in developing countries. However, few documented examples demonstrate the validity of such arguments. The paper explores some practical examples of how, at the grassroots level, individuals and communities are attempting to exploit archaeological heritage sites as well as other cultural and natural heritage resources for income generation in Zimbabwe. The major thrust of the paper is to assess the manner of use and the viability of such ventures. Since the ability of archaeological heritage to generate revenue and support people around the sites has a direct effect on long-term survival of such heritage, ultimately, the paper contributes to the discourse on linking heritage and economic development as well as the theme of sustainable heritage preservation.     

Justification for reassessing elemental analysis data of ceramics,sediments and lithics using rare earth element concentrations and ratios

The mensuration of multi‐elemental concentrations from assorted archaeological materials has always required great care and attention to detail to ensure good‐quality data and their ensuing interpretations. Although most suspect data were generated before the wide use of computers, error‐free data are not still a certainty. This paper presents the geochemical rationale for a proposed chemical data‐assessment process, using a globally dispersed collection of ceramic, sediment and lithic data. It is argued that this process can allow archaeologists and archaeometrists to investigate systematically older and current data sets and, if need be, alter them to the reliable values they were originally intended to include.     

The technology and production of glazed ceramics from Middle Islamic Jerash,Jordan

Jerash in northern Jordan was, despite a focus on its classical heritage, also active in the Middle Islamic period, but little is known about actual developments during this period. This study represents the first study on the Middle Islamic glazed pottery from the site using scanning electron microscopy energy‐dispersive spectrometry (SEM‐EDS) and thin‐section petrography. The results show that two production traditions existed, each with different provenances. The local production is characterized by a non‐calcareous ceramic body and the use of a high‐lead glaze coloured with iron and copper oxides, whereas the turquoise‐glazed samples, likely imported from Mesopotamia, have a calcareous ceramic body and alkali or alkali‐lead glaze.     

‘M GLOW BLUE’: ARCHAEOMETRIC RESEARCH AT MICHIGAN'S FORD NUCLEAR REACTOR

The Ford Nuclear Reactor operated from 1957 to 2003 on the University of Michigan's North Campus in Ann Arbor, Michigan. Over its 45‐year lifespan, the facility played a key role in archaeometric research, fostering early methodological studies using INAA and supporting archaeological materials science investigations of lithics, ceramics, metals and bone. One small part of the FNR's abundant legacy was the initiation of trace‐element studies of Oaxacan ceramics, which are now beginning to shed light on early exchange interactions and the origin of the Monte Albán state in the Valley of Oaxaca, Mexico, between 500 bce and 200 ce .
