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.  相似文献

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.  相似文献

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 .  相似文献

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.  相似文献

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.  相似文献

ABSTRACT

Regional inequality within Japan has been a key political issue in Japanese politics throughout the entire postwar period. In this analysis, we examine how Japanese parties have positioned themselves on the question of regional inequality, focusing on how the party system response has been shaped by ideas and ideologies. The article analyses two 15-year periods separated by a quarter of a century (1960–75 and 2000–15) during which regional inequalities became a particularly salient and pressing issue. We compare institutional and socioeconomic contexts, broader governing ideas, and policy responses to this issue by major parties in their election platforms (manifestos). We find that party ideology and broader paradigms continued to shape party responses to regional inequality during both periods.  相似文献

Japanese intelligence operations in Scandinavia became active after the collapse of Poland in September 1939. Both the Japanese and the Finns exchanged information on Soviet military cryptography and tried to decrypt the enemy's codes. As a result of the cooperation, the Finns succeeded in decrypting Soviet naval code at the beginning of the Continuation War. Onodera Makoto, Japanese military attaché in Sweden, collected a lot of valuable information on the Allied Powers in the neutral country, though the General Staff in Tokyo disregarded them as unreliable.  相似文献

Japanese–French negotiation for their 1907 entente revealed contrasting approaches to the application of the Open Door principle in China, particularly to the Fukien province after the Japanese victory in the Russo-Japanese War. Having learned about France's wish to receive Japanese guarantee for the safety of its colony in Indo-China, Japan strove to define Fukien as its additional sphere of influence once it had secured much needed loans in the Paris financial market. France tried to resist Japan's request to define Fukien as its sphere by adopting a secret note, and attempted to restrain Japan's future expansion into China by enmeshing Japan in the web of political and financial ententes with itself and Britain supporting Open Door. This approach of France was a continuation of French policy toward East Asia since the Boxer Uprising, securing its economic interests by supporting Open Door rather than pursuing territorial competition with other great powers in China. In contrast, the Japanese government strenuously attempted to weaken the general application of Open Door doctrine in China, and could define Fukien as Japan's additional sphere by securing a secret explanatory note for such a purpose.  相似文献

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.  相似文献

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.  相似文献
