长清仙人台墓地出土青铜器铅同位素比值的初步分析

Preliminary Analysis of Lead Isotope Ratios of Bronze Ware Unearthed from Xianrentai Cemetery in Changqing District

长清仙人台墓地出土青铜器以铅锡青铜为主要材质类别。春秋早期至中期之初,仙人台M3、M2及M6青铜器的铅料与同期中原、汉淮地区一致;中期中段,仙人台M4青铜器开始应用来自长江中游的新的铅料,仍与中原各地基本同步。仙人台春秋诸墓见证了春秋青铜器的第一次铅料演替过程,并可确定新铅料的广泛应用始于仙人台M4阶段,对研究先秦金属流通模式及东周青铜器断代具有重要意义。

The bronzes excavated front Xianrentai cemetery are mainly made of lead tin-bronze.From the 8thto the first halt of the 7thcentury B.C.,the lead materials of Xianrentai M3,M2 and M6 bronzes were consistent to those in the Central Plains and Han-huai regions during the same period.In the second half"of the 7 th century B.C.,the Xianrentai M4 bronzes began to apply new lead materials simultaneously with the Central Plain.The Xianrentai cemetery witnessed the first change of lead resources during Spring and Autumn period,and it can be confirmed that the wide application of new lead materials began at the stages of Xianrentai M4,which is of great significance for the study of metal circulation patterns in the pre-Qin period and the dating or-bronzes in the Eastern Zhou Dynasty.
