【摘要】：古骨中的O同位素分析可以揭示先民和动物的饮用水来源,复原其所处的古环境,可为探索先民的来源地和迁徙状况提供重要的参考信息.选取中国商代都邑级别的郑州小双桥遗址出土的17例动物和先民骨骼,在C、N稳定同位素分析食物结构的基础上,利用O稳定同位素分析,对动物物种间δ18O值的差异状况与饮用水来源、代谢方式和饮食结构的关系,以及先民δ18O值的差异原因和身份进行了探讨.结果表明,不同种属动物骨胶原的δ18O值存在较大差异,并且这些差异与个体饮食中C3和C4食物比重的关系不大,更多地是受饮用水中δ18O值与新陈代谢方式(反刍和非反刍)的影响,反刍类动物明显高于非反刍类动物.此外,遗址中先民的δ18O值也有较大差别,表明这些先民生前可能至少来自2个区域,Ⅴ区丛葬坑H66中埋葬的先民相比Ⅸ区地层中的部分先民,来自于更接近海洋的地区.结合古文献和考古资料,推测Ⅴ区丛葬坑H66中埋葬的先民极有可能是东夷族人.
[Abstract]:The O isotope analysis of ancient bones can reveal the drinking water sources of ancestors and animals, restore their paleoenvironment, and provide important reference information for exploring the origin and migration status of ancestors. In this paper, 17 bones of animals and ancestors unearthed from Xiaoshuangqiao ruins of Zhengzhou in the capital of Shang Dynasty were selected. Based on the analysis of food structure by Con N stable isotopes, O stable isotopes were used to analyze the food structure. The relationship between the difference of 未 18O value among animal species and drinking water source, metabolic style and dietary structure, and the reason and status of 未 18O value difference among the ancestors were discussed. The results showed that there were significant differences in 未 18O values of bone collagen between different species of animals, and the difference was not related to the specific proportion of C3 and C4 in individual diet. The values of 未 18O and metabolism (ruminant and non-ruminant) in drinking water were more affected, and the ruminant was significantly higher than that of non-ruminant. In addition, the 未 18O values of the ancestors in the site are also quite different, indicating that the ancestors may have come from at least two regions before their lifetime. Some of the ancestors buried in the cluster burial pit H66 in area 鈪，
