ABSTRACT

Traditional interpretation of Mississippian copper symbol badges is that they were prestige items associated with both inherited and earned status. In this article we review the current state of knowledge regarding copper symbol badges, introduce two previously unreported examples from the Big Tallassee (1MC1) and Abercrombie (1RU61) sites, and propose a new interpretation for the circulation and disposition of copper symbol badges during the Mississippian and Protohistoric periods. We argue that these objects were initially incorporated into headdresses (worn in both life and death) at major Mississippian towns and then were later transformed into inalienable possessions associated with particular beings, people, or places as large polities collapsed and new political entities were formed.  相似文献

Until today, raw material information of copper (Cu) objects is mostly gained from impurities and trace elements and not from the Cu itself. This might be obtained using its stable isotopes. However, isotopic fingerprinting requires the absence of fractionation during the smelting process. The Cu isotope evolution during outdoor smelting experiments with Cu sulphide ore was investigated. It is shown that external materials, in particular furnace lining, clay, manure and sand, alter the isotopic composition of the smelting products. Cu isotopes are fractionated within low viscosity slag derived from matte smelting. The produced metallic Cu has a Cu isotope signature close to the ore.  相似文献

The ancient Chinese barium copper silicate minerals mainly comprise Chinese purple (BaCuSi2O6) and Chinese blue (BaCuSi4O10), which were widely used from the late Warring States Period to the late Eastern Han Dynasty. In order to clarify the raw material of the pigment, a series of simulation experiments was conducted to produce Chinese purple pigment under varying mineral conditions. The minerals that we applied in the experiment were quartz as the source of silicon, malachite and copper oxide as the sources of copper, barite and witherite as the sources of barium and lead oxide as the source of lead. Simulation experiments showed that the barium copper silicate minerals and the purple pigment can be produced easily when witherite is used as the barium‐containing raw material. From the perspective of mineral resources, the birth of the ancient Chinese pigment associated with a unique barium mineral resource. The Chinese copper‐based pigments are assumed to have been developed independently and are presumably an outcome of historical developments in glazing techniques.  相似文献

The Late Chalcolithic (4400–3950 b.c.) occupation levels from Ovçular Tepesi have yielded a significant assemblage of copper objects and remains of copper production. Together with ore finds, two fragments of nozzle, crucible remains, and a number of small metal artifacts, this assemblage includes the unexpected discovery of three copper axes in an infant burial jar. These axes are the earliest examples of large copper tools known to date in southwestern Asia, whether it is in the Caucasus, Iran, or the Anatolian highlands. More importantly, the fact that these objects were locally produced suggests that significant metallurgical activities were being carried out at Ovçular as early as the second half of the 5th millennium b.c. After presenting the evidence from Ovçular Tepesi, this paper will proceed to a reassessment of the available archaeological and geochemical data concerning the emergence of extractive metallurgy in the southern Caucasus.  相似文献

Metallography and neutron activation analysis have been used to investigate copper artifacts from 19th century archaeological sites associated with the “Copper Inuit” of the west-central Canadian Arctic. A knowledge of the source of the copper from which the artifacts were manufactured - native (local) copper or European (exotic) copper - is important, for example, to studies of the effects of European contact on utilization of native copper and on the general lifestyle of the Copper Inuit. Trace element analysis by neutron activation using the SLOWPOKE reactor has allowed local native copper, from the Coppermine River and Victoria Island, NW Territories, to be clearly distinguished from 19th century European smelted copper, which was found to contain higher concentrations of arsenic, antimony, nickel and selenium. Moreover, optical and scanning electron metallography revealed significant microstructural differences between native copper and the 19th century smelted copper. As a consequence it was possible to differentiate between native copper archaeological artifacts and those produced from smelted copper.  相似文献

This paper argues that the agricultural aspect of the Umm an-Nar economy has been largely ignored by researchers, due to an overemphasis on copper production and trade. This is true at the level of the smallest rural settlements, villages and settlements whose primary focus was agricultural production.
The key social developments of this period have often been explained by linking them to the exploitation of copper ore and its trade with surrounding regions such as Mesopotamia and the Indus. However, this paper will argue — based on quantified pottery analysis — that it is during this time that we see the development, for the first time in the Oman peninsula, of widespread sedentary occupation that was based on small agricultural villages where there is no evidence of copper ore exploitation, thus suggesting that the economic basis of Umm an-Nar society was essentially agricultural.
Furthermore, it will be argued that, through the use of a new survey methodology, it is possible to locate such settlements, even where they have left no traces of monuments, such as tombs or round towers. The methodology allows preliminary comparisons to be made between the intensity of occupation in different periods. The paper also argues that the Umm an-Nar period was one of the most intensive periods of occupation in pre-Islamic history.  相似文献

The saturation magnetization σ of soft baked pottery appears to be determined during the firing process by transitions between the iron oxides magnetite, maghemite, hematite and perhaps goethite. The finding of large variations in σ motivated the design and construction of a ‘magnetization–gravitation’, or ‘MG’, balance for rapid non‐destructive magnetization measurements. The first results with this MG balance are presented: iso‐σ contours, typical histograms and correlations with colour features. Practical MG applications are summarized.  相似文献

In a paper on the effects of the global financial crisis in Central and Eastern Europe (CEE), a European Union economist reacts to a companion paper (Åslund, 2001) published in the same issue of Eurasian Geography and Economics on the influence of exchange rate policies on the region's recovery. The author argues that post-crisis corrections in current account deficits in CEE countries do not in themselves signal a return to steady economic growth. Disagreeing with Åslund over the role of loose monetary policy in fostering the region's economic problems, he outlines a number of competitiveness problems that remain to be addressed in the 10 new EU member states of CEE, along with improvements in framework conditions supporting future macroeconomic growth.  相似文献
