河南安阳市辛店遗址商代墓葬出土青铜器的矿料来源研究

Study of Ore Sources for Bronzes Unearthed from Shang Dynasty Tombs at the Xindian Site in Anyang City,Henan

前言.铸铜遗址所保存的铸铜技术、生产工序、青铜物料、工匠生活等信息,是研究古代青铜工业发展水平的重要材料。铸铜遗址所出青铜器产地较为明确,对这些青铜器进行合金成分和铅同位素分析对于揭示资源流通和青铜器生产模式具有重要意义。

Copper ore source analysis was conducted on 74 bronzes unearthed from the Xindian site in Anyang through lead and copper isotopes.Lead isotope results indicate consistency between variations in lead resources for bronzes from different phases at the Xindian site and those from Yinxu,suggesting possible direct supply of lead resources from Yinxu to the Xindian site.Both the highly radiogenic lead of the Shang Dynasty and the ordinary lead of the Yinxu phase IV culture may have originated from lead mines in western Henan Province,emphasizing the significance of western Henan metal resources,which provided an important economic foundation for sustaining bronze production and stable rule during the Shang Dynasty.Copper isotope analysis reveals that copper used at Xindian was primarily smelted from oxidized ores such as malachite.Copper resources used during Yinxu phases II through IV probably changed,and their exact origins await further study.
