世界铜鼓之王——北流型101号铜鼓铸造工艺研究

体大壁薄的世界铜鼓之三──北流型101号铜鼓是世界上迄今所见最大的一面铜鼓,具有相当大的铸造难度。本文对北流型101号铜鼓的内外陶范及鼓耳的制作方法、内范结构、在外范上直接制作纹饰的方式、浇注工艺和垫片的使用等古代铸造工艺进行了研究。还探讨了该铜鼓的结构特征及鼓足残缺的成因。     

对激光清除青铜器粉状锈技术的分析和探讨

用激光技术清除青铜器文物的粉状锈开辟了防治“青铜病”的一种新途径.本文阐述了粉状锈生成机理和激光清除粉状锈的基本理论,介绍用激光器处理粉状锈的一些实际情况.对把激光用于清除粉状锈,作者提出了从理论到实际应用中的一些看法,且认为该技术目前仍处于试验阶段。采用何种类型的激光器?如何控制激光参数?还需要做大量的试验和研究.进而指出,用非调 Q 脉冲式钕玻璃激光器进行清除工作,实际上对青铜器会带来严重损伤,对珍贵的青铜器文物不宜采用.     

铅同位素考古研究的可行性问题——浅议“青铜器铅同位素指示意义的范铸实验研究”

国际上对铅同位素示踪方法在青铜器原料产地研究中的应用做过很多探讨。《范铸》一文再次提出有关问题,认为铅同位素分析结果不能确切指示青铜器铜锡铅原料的来源信息。本文考察了其依据的实验数据,它们似乎与其观点互相矛盾,其结论说服力相当有限。     

辽东半岛古代生存经济模式的转变及其环境背景

本文首先根据对辽东半岛考古遗址中出土的生产工具的统计分析,结合遗址出土的动物骨骼和贝类遗骸的种类及数量,讨论了辽东半岛从小珠山下层时期到青铜时代生存经济的模式及其变化。然后从自然环境变迁、人类对自然环境的影响以及对外文化交流等方面,对上述变化的原因进行了探讨,认为辽东半岛北部区、南部区和海岛区的生存经济模式及其变化,与各区不同的自然环境以及人类对自然资源的影响有关。     

Anthropological and physicochemical investigation of the burnt remains of Tomb IX in the ‘Sa Figu’ hypogeal necropolis (Sassari,Italy) – Early Bronze Age

Excavations carried out in Tomb IX of the hypogeic necropolis of ‘Sa Figu’, near the village of Ittiri (Sassari, Italy), supplied burnt human bone remains and pottery unambiguously referred to the Early Bronze Age (characterised by the local culture of ‘Bonnannaro’). Besides the anthropological study, we have investigated and evaluated the possibility of a funerary cremation practice in Sardinian pre‐history, a subject that has previously not been considered from a scientific point of view. Making use of a calibration procedure based on X‐ray diffraction (XRD) line‐broadening analysis, related to the microstructural properties, it was possible to estimate the combustion temperature to which the fragmented bones were subjected. It was found that the studied bones reached temperatures varying from 400°C up to a maximum of 850°C. This spread of values suggested inhomogeneous combustion of the bones, which seems compatible with funerary cremation practices. Copyright © 2007 John Wiley & Sons, Ltd.

Characterization and textural analysis of Middle Bronze Age Transdanubian inlaid wares of the Encrusted Pottery Culture,Hungary: a preliminary study

Inlaid ceramics belonging to the Encrusted Pottery Culture and dated to the Middle Bronze Age (2000–1500 BC) are highly distinctive vessels with complex decorative motifs found in large numbers in the Transdanubia region of Hungary. Despite this considerable corpus of material there has been little systematic investigation of the composition of the inlays. Micro-analysis of Transdanubian inlaid wares by X-ray diffraction (XRD), micro-Fourier transform infrared microscopy (FT-IR), and scanning electron microscopy (SEM) provides new compositional, structural and textural information on the inlays. In contrast to common statements in the literature regarding the materials used to make inlays, these new data show that the majority of inlays are composed of hydroxyapatite (bone) that was previously ashed, although some of the inlays are composed of calcium carbonate. Additional compositional and textural variation in the bone inlays suggests that bone material from different skeletal elements and/or of different age may have been used, and that contrasting recipes for inlay preparation were employed during fabrication. These results suggest that the production of inlaid vessels of the Encrusted Pottery Culture was more complex than has hitherto been thought.     

Bronze Age upland settlement decline in southwest England: testing the climate change hypothesis

The division of land on Dartmoor during the Bronze Age by the construction of moor-wide boundaries known as reaves represents a significant development in agricultural practice and land tenure. Previous research relating to the Dartmoor reaves suggests this way of life may have continued for no longer than 200–400 years. It has been suggested that their abandonment occurred as the result of a deteriorating climate, although there are no published palaeoclimatic reconstructions from the area. We therefore test the hypothesis that on Dartmoor, a marked climatic deterioration occurred in the late Bronze Age that can be linked to the abandonment of the reaves. A palaeoclimatic reconstruction derived from testate amoebae and peat humification analyses is presented from Tor Royal Bog, central Dartmoor, the first such record from southwest England. A major shift to a cooler and/or wetter climate is inferred from ca. 1395 to 1155 cal BC that is coincident with the period hypothesised as encompassing the abandonment. This climatic deterioration is replicated in sites in northern Britain, suggesting it was a widespread event. It is concluded that while the evidence supports a climatically forced retreat, there are a range of other socio-economic factors that must also be taken into consideration.     

Stable isotope evidence for salt-marsh grazing in the Bronze Age Severn Estuary,UK: implications for palaeodietary analysis at coastal sites

Stable isotope analyses of modern coastal and salt-marsh plant species (‘salt-loving’ plants or halophytes) have demonstrated that these are significantly enriched in ¹⁵N compared to other terrestrial plants. Coastal salt-marshes were far more extensive in the past than they are today. They represented a vast and much-exploited resource in many areas of the UK and north-western Europe and were considered to be prime land for the grazing of animal stock.     

Exchange patterns,boundary formation,and sociopolitical change in Late Bronze Age Southern Caucasia: preliminary results from a pottery provenance study in northwestern Armenia

In the South Caucasus—roughly the territory of today's Armenia, Georgia, and Azerbaijan—the transition from the Middle Bronze Age (MBA) to the Late Bronze Age (LBA) is equated with fundamental shifts in settlement patterns, subsistence economy, and political strategies. During the mid-2nd millennium BC, nomadic pastoral societies that had dominated the region began to settle down and construct stone fortresses along the foothills of the Lesser Caucasus; these fortifications largely replaced the expansive and often opulently adorned kurgan burials as the most prominent expression of political dominance on the landscape. After a decade of intensive archaeological study at various fortifications, very little remains known about the political and economic relationships among fortresses on a regional scale that might improve our understanding of the roots of these sociopolitical transformations. In this paper, we highlight the results of a recent neutron activation analysis (NAA) of ceramics from elite and non-elite contexts at a selection of LBA fortresses on the Tsaghkahovit Plain in northwestern Armenia, and offer some preliminary interpretations about political and economic organization and boundary formation. Most strikingly, the NAA data suggest that the fortresses on the Tsaghkahovit Plain appear to have isolated themselves economically from surrounding valleys, perhaps in an attempt to forge boundaries and legitimating ideologies attendant to new political formations that were quite distinct from their nomadic predecessors in the MBA.
