山西侯马上马墓地青铜器铅同位素比值分析

Lead Isotope Ratio Analysis of Bronze Wares Unearthed from Shangma Cemetery,Houma,Shanxi

山西侯马上马墓地是一处重要的晋国邦墓地,出土了大量东周时期的晋国青铜器。本研究对4件上马墓地春秋中期青铜器开展了铅同位素比值分析,以探讨春秋中期晋国铅料产地。研究结果显示4件青铜器的铅同位素比值均为普通铅,与晋南地区西周晚期至春秋早期青铜器所使用的铅料基本相同,可能产自长江中游地区。上马墓地青铜器与瓦窑坡春秋中期青铜器使用的铅料不同,反映了春秋时期青铜金属资源流通网络的复杂性。

Shangma Cemetery at Houma,Shanxi is an important graveyard of Jin state nobles’,where a large number of bronzes of the Eastern Zhou Dynasty were unearthed.Aiming to explore the origin of the lead materials of Jin State during the mid Spring and Autumn period,this study carried out lead isotope ratio analysis on 4 bronze objects from this site.The results show that the lead isotope ratio of these four bronzes are common lead,which are basically same as that used in the bronzes from the late Western Zhou Dynasty to the early Spring and Autumn period in southern Shanxi.The material were probably from the middle reach of the Yangtze River.The lead materials used in Shangma are different with that in bronzes from Wayaopo site,which reflected that the circulation network of bronze materials was complicated during the Spring and Autumn period.
