关于夏商周碳十四年代框架

中国历史教科书将翻开新的一页,因为新的夏商周三代年表公布了,它将中国有确切纪年的历史向前推进了 １２２９年。 由历史学、天文学、考古学和Ｃ测年技术等学科的２００多位专家参加的我国建国以来社会科学领域规模最大的科学研究项目—夏商周断代工程,历经４年多的时间,终于实现了既定的目标,建立了三代年表。这标志着我国在年代学方面的研究又迈上了新的台阶。 夏商周三代年表从西周共和元年的公元前８４１年到公元前２０７０年跨越中国早期的三个朝代,总年数长达１０００多年,中间涉及了许多重要的年代定点和时段。其复杂性、其…     

Developing a Landscape History as Part of a Survey Strategy: A Critique of Current Settlement System Approaches based on Case Studies from Western New South Wales,Australia

In Australia, geomorphological change since the late nineteenth century ensures surface artifact visibility but the contribution of full coverage regional survey to an understanding of past landscape use is limited by the lack of easily datable artifacts. Here, we describe a multi-stage survey strategy based around intensive archaeological, geomorphological and chronological studies as an alternative to traditional site-based approaches. We view the formation of the archaeological record as a sedimentary process and use a geomorphological approach to understand the history of landscape use from surface artifact scatters. We pay particular attention to recording datasets with reference to the timescales over which they have accumulated, and we discuss the types of behavioral inferences that can be drawn from the results of intensive survey, illustrated using the results from our western New South Wales research.     

Expanding the utility of Uranium-series dating of speleothems for archaeological and palaeontological applications

Uranium-series (U-series) dating of speleothems is frequently used for palaeoclimate studies but its archaeological and palaeontological applications are limited to stratigraphically significant speleothem formations, such as flowstones, to provide maximum and minimum temporal points. This study targeted soda straw stalactites for U-series dating. In contrast to other speleothem formations, soda straw stalactites are fragile, have typically short life spans (usually only years but rarely up to a few hundred years) and are frequently incorporated into cave deposits. Results of thermal ionisation mass spectrometry (TIMS) U-series dating of soda straw stalactites from palaeontological excavations at Blanche Cave, South Australia, show that small, dense, clean straws tend to yield ages closest to the time of stratigraphic deposition. A correlation between soda straw U-series ages and radiocarbon ages of charcoal from the site is shown. Multiple soda straw age determinations for a single stratigraphic unit are required in order to verify age concordance. In conjunction with other dating methods, U-series dating of soda straw stalactites may help to significantly constrain the age of stratigraphic units and associated archaeological and palaeontological deposits in order to provide more robust chronologies. Here we advocate the collection of soda straw stalactites at future excavations of limestone cave sites.     

Hayonim Cave: a TL-based chronology for this Levantine Mousterian sequence

The thermoluminescence dating method was applied to 77 heated flints from the Mousterian layers of Hayonim Cave in order to provide a precise TL-based chronology for this important Levantine sequence. A detailed dosimetric study was performed by using 76 dosimeter capsules and revealed strong spatial dose-rate variations. In parallel, Fourier transform infrared spectrometry enabled the identification of various mineral assemblages in the sediments of the cave and to localize the boundaries of these assemblages. By comparing these two data sets, it is shown that low dose-rate values (∼500 μGy/a) are systematically recorded in areas where the calcite-dahllite (CD) assemblage is preserved, whereas higher values (up to 1300 μGy/a) are associated with the leucophosphite, montgomeryite, variscite and siliceous aggregates (LMVS) assemblage. The dosimetric and mineralogical information was combined in order to assess, where possible, the dose-rate experienced by each flint during its burial. Some of the flint samples analyzed were too close to mineral assemblage boundaries and were therefore discarded. This rigorous selection led to TL ages ranging from 230 to 140 ka for the lower part of the Mousterian sequence (layers F and Lower E), which contains lithic industries characterized by blade production using the laminar method.     

清末民初的“纪年”变革与国家建构

清末,中国传统时间思维受到西方线性时间观念的冲击而发生根本变革,纪年变革就是这种变化最为直接的表现。知识分子将纪年视为建构＂现代国家＂的重要方面,并为争夺纪年所具有的政治资源展开激烈论争。民国建立之后,革命党人将建构新纪年体系视为革新政治的重要标志,并在社会上大力播扬新纪年的意义,此做法却受到了普通民众的抵制。时间观念及与之相伴的生活习俗与现实政治之间的复杂关系是近代社会变革的重要论题。

New radiometric dating of water management features at the prehistoric Purrón Dam Complex,Tehuacán Valley,Puebla, México

Recent investigations at the prehistoric Purrón Dam Complex in the Tehuacán Valley of southern Puebla, México applied radiometric dating to more securely date the complex. Ceramic-based dating in the 1960′s placed the Dam's origin to the Formative Period. While Formative Period origins are widely accepted, the chronology lacks resolution and direct dates. Samples from impounded sediments behind the dam and from prehistoric canal fill were dated through Optically Stimulated Luminescence (OSL) as well as both standard ¹⁴C and accelerated mass spectrometry (AMS) assays. These samples directly date the functioning of the water management features within the complex. The results confirm the Formative Period origins of the Purrón Dam, and offer new insights into the construction and functioning of the dam and irrigation system.     

夏商周断代工程与夏商考古学文化研究

学习和了解自己的历史是每个国家的共同追求。中华文明是人类历史上少有的独立起源的古代文明之一 ,绵延流传 ,从未中断 ,世所罕见。无论是战乱、暴政或外族入侵及水旱灾疫 ,都未能阻止中华文明的持续发展和进步。历史的长河培育了伟大的民族精神 ,造就了民族的伦理道德 ,形成了强大的民族凝聚力。数千年来 ,我们的祖国虽然经过多次分裂 ,继之而来的是又一次的大统一。但中国历史还缺少夏商周以前和夏商周大部分的确切年代 ,我国古书记载的上古确切年代 ,只能依照司马迁的《史记·十二诸侯年表》追溯到西周共和元年即公元前 84 1年 ,再往上…     

Tree-rings and archaeology: some problems explained

Some uncertainty amongst archaeologists about dendrochronology has prompted an explanation of some of the points which cause most concern. These include the probability of obtaining a date for a wood sample and the reliability and accuracy of that date. Uses of tree-ring analysis, other than for dating, are also mentioned.
