Patterns of plant δN values on a Greenland Norse farm

In a further empirical study of the impact of past human activities on modern plant δ¹⁵N values, plants were collected in each of two growing seasons from several defined contexts of an inland Norse farm in southwest Greenland. The δ¹⁵N measures of the plants show a clear distinction between areas with definite evidence of past human activity and those without. The data for the plants on this farm's infield indicates that it was purposely fertilized. The intriguing intra- and inter-variations in the ¹⁵N values of plants from several structures are not easily explained, but the differences appear to reflect the different functions of the various farm structures. The findings of this study suggest practical applications for future use of plant δ¹⁵N values in archaeology.     

Strangers in the grave? Investigating local provenance in a Greek Bronze Age mass burial using δS analysis

The present study employs δ³⁴S analysis to investigate the potential of this method in the investigation of local/geographic origin for the 12 individuals buried collectively over the ruins of a Bronze Age building, under a tumulus, in Thebes, Greece, and to help in the understanding of this unique case in Greek archaeology. Sulphur isotope analysis of bone collagen is applied with increasing frequency to elucidate aspects of paleodiet and movement in archaeology. Sulphur is linked to local geology and can also be used to indicate proximity of people and animals to the sea. The osteoarchaeological analysis of the assemblage revealed that it included individuals of both sexes and all age groups, a configuration which could traditionally be interpreted as an extended family. The absence of synchronous burials in Thebes amplifies the importance of this assemblage. At the same time, traditional archaeological practice has been unable to elucidate the conditions that led to this event, proposing a biological affinity for the individuals and personal reasons for their extinction. However, sulphur isotope analysis clearly demonstrated that at least one of the individuals had spend the last years of life in an environment different from the rest, a fact likely to indicate a rather random composition of this assemblage.     

Geographic variation in bone carbonate and water δO values in Mendoza,Argentina and their relationship to prehistoric economy and settlement

Questions of mobility, settlement pattern, and their relation to economic organization and resource use are central to ongoing work in central-western Argentina. Here we analyze geographic patterns in the distribution of 178 human bone carbonate δ¹⁸O samples, 46 human tooth enamel carbonate δ¹⁸O samples, and 48 water δ¹⁸O samples from throughout the Andean Cordillera and Monte Desert and evaluate their implications for prehistoric mobility and economy. We confirm and refine previous generalizations regarding a highland/lowland dichotomy in water δ¹⁸O values and show that the range of human carbonate δ¹⁸O values generally reflect available water sources. While there is little within-lifetime change in patterns of water use, we show that most individuals have stable isotope signatures consistent with water use from multiple areas or areas other than where they were ultimately interred. These data indicate high levels of residential mobility, and we conclude by discussing their implications for our understanding of regional prehistory.     

汉阳陵地下博物馆遗址表面硫酸钙(CaSO4·2H2O)形成原因探析

汉阳陵地下博物馆是我国首个遗址保存在恒温恒湿环境的博物馆,但遗址表面仍然析出了硫酸钙(CaSO_4·2H_2O)。本研究通过对汉阳陵13号坑封闭展厅内环境温湿度、土壤蒸发量、遗址本体及地下水可溶盐的长期监测分析硫酸钙(CaSO_4·2H_2O)产生原因。结果表明,13号坑环境湿度长期保持100%,由于遗址表面温度高于露点温度,空气中水分子在土壤表面不能转化为液态水返回到土壤中,而随着土壤水分蒸发遗址表面土壤溶液浓度逐渐增大,溶液中离子相互发生反应在遗址表面析出白色的硫酸钙。

我的徽菜(外二篇)简

我外公在去世前的很长一段时间,生活得很简朴,牙口也不太好,他总是喜欢呆呆地坐在八仙椅上,一边嚼着馒头喝着稀饭,一边极慢地呷着从街上打来的山芋干酒,沉默不语,像一头缅怀岁月的老牛。这个时候的外公,已拿不动锅铲烧菜烧饭了。在此之前,外公的菜一直烧得很好。徽州人烧菜似乎是无师自通的．不仅仅是外公,
