内蒙古赤峰市二道井子遗址出土铜器的初步科学分析

A Preliminary Scientific Research on Copper Artifacts Unearthed from the Site of Erdaojingzi,Chifeng City,Inner Mongolia

近年来,关于中国早期铜器(本文中指商代以前的铜器)的研究已取得一系列重要的新进展。研究表明:西北地区出土的早期铜器不仅年代早、数量多、种类全、分布广,而且材质多样;既显示出与欧亚草原青铜文化关系密切,也有证据表明与中原和北方地区存在联系或互动。相比之下,北方地区的早期铜器发现不仅年代晚,而且数量也少,主要见于夏家店下层文化和朱开沟文化的一些遗址。已有不少学者致力于北方地区出土早期铜器的科学分析研究,发表的相关论著主要有:李延祥等人的《敖汉旗大甸子夏家店下层文化墓葬出土铜器初步研究》、贾海新的《夏家店下层文化药王庙类型的铜器初步研究》。

The discovery and excavation of the Erdaojingzi site in Chifeng,Inner Mongolia are significant for the study of the Lower Xiajiadian Culture,which is the most important site with early Bronze Age culture found in Northern border region of China.This paper presents the results of scientific analysis of nine copper and bronze objects excavated from the site.It has been shown that among these objects,one is pure copper and the others are Cu-Sn alloy.Microstructure examinations show that three earrings were shaped by hot-forging technique,which is similar to the technology seen at the Dadianzi site of the Xiajiadian Culture.The results of this research provide significant new information for understanding the development of bronze technology of the Lower Xiajiadian Culture in northern China.
