This article outlines recent advances in establishing and understanding the prehistoric sequence in mainland Southeast Asia. Research has been unevenly distributed, varying from virtually none in Cambodia to a marked intensity in Hong Kong and the adjoining mainland. A new pattern is becoming apparent, due in no small part to the new findings in southern China. It is argued that despite its long history of occupation, beginning withHomo erectus almost a million years ago, tropical Southeast Asia was occupied by scattered inland groups and larger, possibly sedentary coastal foragers until exposed to intrusive agricultural societies during the third millennium BC. These communities, which originated ultimately in the Yangzi Valley, brought with them rice cultivation and were responsible for the wide distribution of Austroasiatic languages. The three divisions of this language superfamily are now distributed from eastern India to southern China. Following a relatively brief Neolithic period, small and autonomous communities, particularly in Lingnan and Bac Bo (Guangdong and Guangxi provinces of China and the area of the Red River Delta), were exposed to exchange contact with the Shang state of the Chinese Central Plains, and this brought exotic jades and bronzes. Within this context, a local bronze industry was established between 1500 and 1000 BC over much of Southeast Asia, but without any obvious social developments until the middle of the first millennium BC, when several major changes occurred. These incorporated iron smelting and forging and exposure in the southern parts of the region to Indian mercantile contact and along the northern margins to the expanding Chinese empire. Adaptations varied regionally, from the establishment of warrior chiefdoms to counter the Chinese to the construction of water control systems in the arid heart of Southeast Asia to alleviate environmental unpredictability. It is within these regional changes that we can identify trends toward the establishment of states, some of which persisted in an unbroken lineage to the present.  相似文献

In this article, we present the results of application of petrographic and neutron activation analyses to a group of pottery fragments dating to the 12th century BCE deriving from ancient Eleon (Boeotia, Greece) as a means of investigating regional and interregional networks in which the site participated. Production centres in Boeotia and central Euboea provided, as could be expected, the majority of sampled pottery across various shapes. A number of more distant areas, however, such as eastern Attica, the Cyclades, Macedonia, and western Crete, are also documented in the present study, suggesting their products were available to local consumers at ancient Eleon. These results are discussed with reference to consumer preferences and exchange networks operating at that time. Finally, some of the identified petrographic and chemical groups can be securely identified at the macroscopic level, allowing us to arrive at conclusions pertinent to a substantial part of the entire pottery assemblage.  相似文献

We analyze the firm-level labor productivity growth returns of social capital—defined as a synthetic measure of “generalized trust,” “active participation,” and “social norms”—using a large sample of manufacturing firms in France, Germany, Italy, Portugal, and Spain. We find that firms' labor productivity growth is higher in areas with a better social capital endowment. The positive returns of social capital are, nevertheless, unevenly distributed across firms, with smaller, less productive, less capital-endowed, and low-tech firms benefitting the most from operating in strong social capital ecosystems.  相似文献

对12件山东古代青铜镜进行了金相分析,其中6件为铸态,6件为热处理态,热处理的基本特征是:观察面上可看到许多明晃的交叉状物和不太明显的晶界状、环链状物。这与我国古镜的特征组织是一种“两端尖锐的长条状及针状”物之说是不相符的。  相似文献

Recent research by Chinese archaeologists has identified many late prehistoric (2000-400 B.C.) oases, pastoral settlements, and cemeteries in eastern Central Asia (Xinjiang province of China). The synthesis presented here organizes the data into 10 archaeological cultures, defined on the basis of ceramics, burials, small finds, and architecture. The archaeological cultures reveal two periods, corresponding to the Bronze Age and the Iron Age. The oases cultures formed a core area before the Chinese Han period and maintained close contacts with nearby highland pastoralists in Siberia and western Central Asia. The evidence for interaction between Xinjiang and the complex cultures in China and western Central Asia is evaluated with regard to the origins of the early Xinjiang cultures.  相似文献

杭州萧山老虎洞东周遗址出土两件青铜工具,工具出土时已碎裂为数段,锈蚀状态严重。针对两件青铜工具的研究,主要从微观领域来探讨青铜工具的工艺技术及腐蚀特点,并通过建立电化学反应模型,运用电极电位差的理论,来试析电极电位对金相组织腐蚀的影响。同时提出在青铜修复时,可利用电极电位的原理来补配修复材料,以达到文物保护的目的。  相似文献

Between 2010 and 2012, the AROURA project conducted magnetometric prospection in the ancient polder around the Late Bronze Age (ca. 1300–1190 b.c.) fortress of Glas, mainland Greece. As had been hypothesized, the anomalies detected were consistent with a system of agricultural fields. This system appears to have been irrigated and drained through previously identified hydraulic mechanisms in and around the polder. Comparison of soil profiles of anomalies with those of background areas, including their magnetic susceptibilities, corroborated magnetometric data. Anomalies were traced from sampled to unsampled areas through corresponding reclassified satellite bandwidths. Constituent sediments of features discovered were dated to the Late Bronze Age through AMS radiocarbon and OSL analyses. The results validated the use of extensive geophysics to detect and investigate ancient agricultural landscapes.  相似文献

This paper presents the latest methodological advances using the LA‐ICP–MS technique for differentiating the origin of petrographically and chemically similar ceramic raw materials. Based on several examples form the Armorican Massif (France), from a chronological period extending from the Neolithic to the Second Iron Age, we will show that the comparison of the chemical signatures of minerals included in fired clay with those from clay and source rocks enables us to distinguish productions and to accurately trace the sources of the raw materials used by potters.  相似文献

ABSTRACT

The Tell es-Sultan, ancient Jericho, is amongst the earliest “cities” that rose in the Southern Levant between the end of 4th and the beginning of the 3rd millennium BCE. The site is being excavated, studied and rehabilitated for tourism by Sapienza University of Rome and the Palestinian Ministry of Tourism and Antiquities since 1997. In 2017, during the 13th season of excavation, an unexpected discovery occurred: five Chambardia rubens shells have been found piled up in a dwelling unit dating back to the Early Bronze Age IB-II. The discovery is a tangible evidence of trade and cultural interconnections between the Southern Levant and Egypt, as these shells belong to a species that is only been found to live in the Nile. Moreover, chemical analysis, and thorough Scanning Electron Microscopy examination revealed that the shells contained Manganese Dioxide, an inorganic compound used as make-up ingredient in ancient Egypt, and available in the ores of the Sinai. These findings strongly support the existence of a link between the urban rise in EB IB-II through international trade of luxury goods, and are suggestive of the emergence at Jericho of a ruling elite that was influenced by Egypt.  相似文献

为深入研究古代青铜器示踪矿料来源中矿料混合问题,通过铅同位素研究数据构建矿料混合模型,从理论上探讨满足条件的青铜器数据样本其矿料混合的情况。基于模型,通过对铅同位素数据的处理,不仅能够匹配相应的矿料混合模式,而且可为器物分类提供依据。此外,还可计算出相应的铜料中表观含铅量,为相关研究提供参考依据。  相似文献
