| 摘 要： | 基于富集在铜料中而保留其母矿信息的元素可以用于示踪青铜器的矿料来源,为了解郑韩故城青铜器的矿料来源,利用ICP-AES方法对郑韩故城出土东周时期青铜器的微量元素进行了检测。结果显示,21个青铜器样品微量元素特征具有相对一致性,推测可能具有相同的原料来源。与小双桥遗址出土青铜器的微量元素特征进行对比,二者存在明显的差异,说明从商代中期到春秋战国时期,这一地区的原料来源发生了改变。研究结果可为研究东周时期这一地区铜业发展状况提供线索。

| Abstract: | Elements containing information of the mother lode and concentrated in copper after smelting of copper ore can be used to deduce the source of materials in bronze .In order to study the provenance of copper minerals, the trace elements of 21 bronzes excavated from the ancient city of Zheng and Han in the Eastern Zhou Dynasty are analyzed using Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). The analytical results showed that the compositions of the trace elements in the bronzes are relatively uniform, and from this it could be inferred that the ores are from the same or similar mining sites. There are some remarkable differences between the traces elements identified in objects from ancient capital city of Zheng and Han and those from the Xiaoshuangqiao site. This illustrates that the ores chosen for casting changed between the middle-Shang and Spring and Autumn periods in this area. The results of the study can provide clues to the mineral provenance of bronzes. |
