周原贺家遗址铜马车的矿料来源

周原地区是周文化的起源地，也是研究我国西周青铜器重点区域。采用扫描电镜能谱仪（SEM-EDS）和多接收电感耦合等离子体质谱仪(MC-ICP-MS)对贺家遗址的铜马车进行成分分析和铅同位素比值分析，以探讨该铜马车的合金配比及矿料来源。成分测试结果显示周原贺家铜马车合金类型为锡青铜。同位素比值分析结果显示样品的铅同位素比值均属于普通铅的范围。通过与秦岭矿石进行对比，发现其铅同位素比值与陕西境内秦岭地区的数据较为接近，说明秦岭金属资源可能在西周得到开发。本研究为周原地区西周青铜器的矿料来源研究提供了新的科学依据。

Source of Mineral Materials of Bronze Carriage at Hejia Site in Zhouyuan

Zhouyuan area is the origin of Zhou culture, and it is also one of the important areas to study bronzes of the Western Zhou Dynasty in China. In this work, SEM-EDS and MC-ICP-MS were used to analyze the composition and lead isotope ratio of the copper carriage in Hejia site. The composition test results show that the alloy type of Zhouyuan Hejia copper carriage is tin bronze. The isotope ratio analysis results show that the lead isotope ratios of samples belong to the range of ordinary lead. By comparing with the ore, it is found that lead isotope ratio is close to the data of Qinling region in Shaanxi province. This study shows that the metal resources of the Qinling Mountains may have been developed in the Western Zhou Dynasty, which provides a new scientific basis for the study of ore source of bronzes of the Western Zhou Dynasty in Zhouyuan area.
