We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies. 相似文献

This paper re‐analyses a considerable corpus of glass from the Late Bronze Age site of Nuzi, found near Kirkuk in Iraq. SEM–WDS and Sr and Nd isotopic analysis were applied, in addition to cataloguing the glass. The work showed that the glass technology at Nuzi was subtly different from contemporary Egyptian sites, using different ways of opacifying and working glass. At least two, perhaps three, Near Eastern production sites are postulated. The range of glass colours and the skill of their application at Nuzi was perhaps not on a par with the Egyptian sites. This led to a reconsideration and review of the accepted wisdom that the Near East is the source of the innovation that is glass‐making. This opinion is based on limited textual and iconographic sources and is dominated by an erroneous early date for a very developed Nuzi glass industry along with a few finds of glass vessels in early contexts. Some of this evidence has now been at least questioned, suggesting that glass‐making in Egypt, at least as early as the middle of the 15th century bc , and probably earlier, is no later than that in the Near East. It is argued that it is far from clear that the Near East was the source of the innovation and that a more cautious approach would better fit the evidence. 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

铅钡硅酸盐是中国古代费昂斯和玻璃制品的典型成分类型。本文首先明确了铅钡硅酸盐制品包含铅钡釉陶、铅钡釉砂、铅钡玻璃以及硅酸铜钡颜料四大类,并重点讨论前三者,强调不宜用“铅钡玻璃”指代铅钡硅酸盐制品。其后,文章整体梳理了战国时期铅钡硅酸盐制品的出土范围和存续时间。在此基础上,重新讨论了铅钡釉陶、铅钡釉砂、铅钡玻璃的关系问题,提出铅钡釉陶和铅钡釉砂都不是铅钡玻璃的先驱,三者在战国早期的出现更像是铅钡这种全新助熔剂在不同材质上的应用。 相似文献

明清时期国家对于汉水下游的水利管理制度经历一个变迁的过程,与这一区域的水利问题的日益突出密切相关,垸田的发展以及带来的问题是主要的因素。钟祥至沙洋的汉江干堤极易溃决,并且关系到整个下游地区的安全,因此在人力组织、资金筹集、岁修维护上,国家的政策表现出明显的倾斜性,相对于沙洋以下的区域,给予了充分的重视。沙洋以下,天门、潜江、沔阳等州县所在区域主要以垸田为主,国家将这一区域的堤防修筑与维护主要交由地方来进行。垸堤岁修维护采取堤甲制的组织形式,由垸民完成,一方面没有固定的资金,另一方面在正常年景之下,垸民可以获得基本的物质生存,因此垸堤的维护面临相当的困难。 相似文献

This paper reports the earliest securely dated evidence for intentional dental modification in West Africa. Human remains representing 11 individuals were recovered from the sites of Karkarichikat Nord (KN05) and Karkarichinkat Sud (KS05) in the lower Tilemsi Valley of eastern Mali. The modified anterior maxillary dentitions of four individuals were recovered from KN05. The dental modification involved the removal of the mesial and distal angles of the incisor, as well as the mesial angles of the canines. The modifications did not result from task‐specific wear or trauma, but appear instead to have been produced for aesthetic purposes. All of the filed teeth belonged to probable females, suggesting the possibility of sex‐specific cultural modification. Radiocarbon dates from the site indicate that the remains pertain to the Late Stone Age (ca. 4500–4200 BP). Dental modification has not previously been reported from this region of West Africa and our findings indicate that the practice was more widespread during prehistory.

During the Late Intermediate period (LIP, c. A.D. 1000–1400), the central Andes experienced the decline of the Wari and Tiwanaku states, as well as processes of state formation, regional population growth, and competition culminating in the imperial expansion of the Chimú and Inka polities. The LIP holds the potential to link the archaeological features of early Andean states with the material signatures of the later ones, providing a critical means of contextualizing the intergenerational continuities and breaks in state structures and imperial strategies. The recent proliferation of LIP research and the completion of a number of regional studies permit the overview of six LIP regions and the comparison of highland and lowland patterns of political and economic organization, social complexity, and group identity. 相似文献

During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use. 相似文献
