骨骼中无机质的主要组成成分为羟磷灰石,羟磷灰石中的微量元素又是人类饮食结构的潜在表现物,活体骨骼中微量元素的含量是饮食中微量元素的最好体现,而被埋葬的骨骼经过沉积作用后骨骼中微量元素变化较小,是其生前获得微量元素的合理反映。因此分析骨骼内羟磷灰石中的微量元素,是探索古代人类的食物结构的重要方法。
In recent years, the study on palaeodiet is one important research in the international archaeological field. Trace elements in human bones can provide a lot of valuable information to reconstruct ancient diet. In this study, nine trace elements in Bronze age human bone from Gumugou cemetery in Luobunaoer, Xinjiang were determined by ICP-AES. They are ferrum (Fe)、zincum (Zn)、calcium (Ca)、phosphornm (P)、manganum (Mn)、magnesium (Mg)、strontium (Sr)、baryum (Ba)、cuprnm (Cu). This analysis established Xinjiang's consult system of trace elements analysis for ancient human bones. Results indicacated that the ancient inhabitants in Luobunaoer primarily ate meat products with only a small amount of plants.
