正阳闰楼墓地出土商代铜器的检测及相关问题研究

河南驻马店正阳闰楼商代晚期墓地是商代南土的一处重要墓地,出土青铜器与殷墟铜器有着诸多相似特点。研究该批铜器的制作技术和矿料来源,对于探究商代晚期中原与周边地区青铜技术的关系、铜料的流通以及由此蕴含社会管理信息有着重要的学术意义。利用金相组织观察和扫描电镜能谱对闰楼墓地出土部分铜器进行了显微组织和成分分析,结果表明,闰楼出土铜器中容器的锡含量明显较高。另外,闰楼墓地铜器多为高放射性铅同位素,这一结果也与商代晚期多地的高放射性现象一致。

Scientific Studies of Bronze Artifacts Unearthed from Runlou Cemetery

Runlou cemetery, in Zhengyang County, Henan Province, of late Shang dynasty period is an important cemetery in Southern territory of Shang dynasty. Bronze artifacts unearthed here are similar with those unearthed from Yinxu site. It is significant to study spreading way of bronze technology and transforming path of raw material in Late Shang Dynasty through investigation on manufacture technoloty and raw material. The microstructure and composition of bronze artifacts unearthed from Runlou cemetery were investigated by SEM-EDS. The results indicate that bronze vessels of Runlou cemetery have high content of tin, moreover, the highly radioactive lead isotope shows that bronze artifacts of Runlou has the same characteristics with those unearthed from several sites in late Shang dynasty.
