木炭在考古学研究中的应用   总被引:1,自引:0,他引:1  
利用考古发掘出土的木炭可以重建考古遗址周围的环境,重建植物群,探索遗址的居民与自然界植被的关系,寻找有关古人类的信息。该对木炭在考古学研究中的可行性、必要性及取样与鉴定方法进行了简要的概括,并以研究实例进一步说明木炭的鉴定过程,对拓宽我国科技考古研究方法有一定的意义。  相似文献

We studied interrelationships among age, sex, and cross‐sectional cortical bone dimensions using quantitative computed tomography (QCT) scans of metatarsal bones of 180 moose (Alces alces) that died in Isle Royale National Park, Michigan. As a large‐bodied quadruped with demanding ecological constraints on movement and behaviour, a moose experiences different weight‐bearing and mechanical stressors than humans, to whom most existing studies of mechanical adaptations of bone pertain. In moose, both sexes showed significant subperiosteal expansion and an increase in medullary area, with an overall increase in cortical bone area over time. Female moose did not exhibit cortical thinning or reduction in cross‐sectional area with age, rather they showed an increase in cortical bone area with periosteal apposition exceeding endosteal resorption, similar to the males. We also found that moose undergo changes in bone geometry through remodelling of bone similar to humans, suggesting a compensatory mechanism for increasing bone strength under conditions of decline in bone mineral density with age.

The biased way in which some inferences may be drawn from archaeobotanical assemblages, due to problems in identification, is briefly discussed. A potentially important class of plant remains, vegetative parenchymous organs, commonly sources of food, are indicated as being such a class rarely identified from archaeological contexts. Their identification based on characters of the plants' anatomy and morphology together with an understanding of the way in which tissues degrade on preservation by charring is suggested. Characters of the charred tissues that make up vegetative parenchymous organs are described in detail. The processes of sorting and identification are then briefly discussed.  相似文献

This paper ponders a number of theoretical and methodological aspects concerning historical archaeology and resulting from an analysis of their development and integration with disciplines such as history, ethnohistory, and anthropology. Special attention is paid to how these are involved in the research of documentary evidence and how the different approaches have an influence on a given case. The authors' viewpoint in the matter is explained and reported on the basis of the fleldwork they conducted at an archaeological site: a midnineteenth-century fortlet located in the center of Province of Buenos Aires, Argentina.  相似文献

Correct identification of textile fibres is an important issue in archaeology because the use of different materials can yield crucial information about the society that produced the textiles. Textiles made of plant and animal fibres can normally be easily distinguished, but to distinguish between different types of plant fibres, in particular different types of bast fibres, is difficult. Some years back it was shown that the features fibre diameter, lumen diameter, dislocation (nodes), and cross markings cannot be used on their own to distinguish between the typical bast fibres used for textiles in ancient Europe: flax, hemp, and nettle. Particularly not when only a few fibres are available for an examination so that statistical analysis is not possible, as is often the case in archaeology. The last two characterization features typically used to distinguish between bast fibres are cross‐section shape and lumen shape. In this paper, we present a study of retted and unretted fibres (in the stem) of flax, nettle, and hemp, and show that also cross‐section shape and lumen shape cannot be used as distinguishing features on their own.  相似文献

从广西民族博物馆易滋生霉菌的展柜里分离、纯化及鉴定了三株霉菌,并研究香叶精油、罗勒精油和山苍子精油对霉菌的抑菌效果,测试这些植物精油喷洒于纸张表面后纸样的防霉性及鉴定三种精油的主要抑菌活性成分。实验结果显示,三种供试植物精油对霉菌均具有显著的抑菌效果,在纸张上的防霉效果也很明显,其综合抑菌效果大小为:香叶精油罗勒精油山苍子精油。GC-MS分析表明,香叶精油的主要活性成分为:香叶醇(56.73%)、橙花醇(38.31%)。罗勒精油的主要活性成分为:丁香酚(83.14%),己二醇(16.15%)。山苍子精油的主要活性成分为:柠檬醛(36.01%),(Z)-3,7-二甲基-2,6-辛二烯醛(29.71%)和柠檬烯(16.67%)。植物精油作为博物馆展存环境的空气防霉剂具有良好的应用前景。  相似文献

New excavations at Border Cave use high-resolution techniques, including FT-IR, for sediment samples and thin sections of micromorphology blocks from stratigraphy. These show that sediments have different moisture regimes, both spatially and chronologically. The site preserves desiccated grass bedding in multiple layers and they, along with seeds, rhizomes, and charcoal, provide a profile of palaeo-vegetation through time. A bushveld vegetation community is implied before 100,000 years ago. The density of lithics varies considerably through time, with high frequencies occurring before 100,000 years ago where a putative MSA 1/Pietersburg Industry was recovered. The highest percentage frequencies of blades and blade fragments were found here. In Members 1 BS and 1 WA, called Early Later Stone Age by Beaumont, we recovered large flakes from multifacial cores. Local rhyolite was the most common rock used for making stone tools, but siliceous minerals were popular in the upper members.  相似文献

Vegetative remains of four dyeplants (Rubia tinctorum L., Genista tinctoria L., Diphasium complanatum (L.) Rothm. and Isatis tinctoria L.) found in 9th–10th century deposits at York, are described in detail. A fifth species (Reseda luteola L.), so far only found as seeds, is also described.  相似文献
