Lead Stable Isotope Analysis of Shang Bronzes Unearthed from the Liujiazhuang Site in Jinan

青铜器研究,包括铭文、形制风格、制作工艺、流通消费等,是了解商文明的五条途径之一1"。张光直先生提出商人通过控制青铜资源以及青铜器的生产和流通来维持其统治121,刘莉和陈星灿先生进一步指出商代的扩张是为了资源的控制和获取|31,但是也有学者认为商王对于周边地区的控制并不是非常强|41。单纯从传统考古学的角度很难给出一个明确的答案,而通过对青铜器的科技检测可以确定其生产技术及矿料来源,从而为这些理论的探讨提供更多的数据支撑,也可以对现有理论进行检验。

This article mainly presents results of lead isotope analysis of some bronzes uncovered from the late Shang Liujiazhuang site in Jinan.Most of the Liujiazhuang bronzes contain highly radiogenic lead and these isotope signatures fall within a relatively small range.By comparing the lead isotope data from Liujiazhuang with that of other Shang period sites,two minor fl uctuations in highly radiogenic lead isotope values during the mid-Shang period and Yinxu phase II can be detected.These highly radiogenic lead isotope data refl ect resource homogeneity across different phases in the Shang Dynasty.Understanding of the socio-economic implications behind these data,however,calls for an interdisciplinary study of typology,bronze casting technology,style and bronze inscriptions.
