吉林白城双塔墓地出土铜器的铅同位素研究

研究了吉林省白城市双塔墓地出土铜器的铅同位素组成,基本认定该墓地出土铜器可能有多个矿料来源,且发现一件器物中含有高放射成因铅。由于内蒙古井沟子西区墓地与双塔墓地的年代相近及人种相似,因而将二者铜器的铅同位素组成进行对比,以确定是否使用了同一矿源。结果表明,双塔墓地的铜器虽然含有不同的矿石来源,但有些铜器的矿石来源与井沟子西区墓地铜器的矿石来源相同(或相似)。

Lead Isotope Analysis of Bronze Unearthed in Shuangta Cemetery in Baicheng of Jilin Province

Lead isotope composition of bronzes unearthed in Shuangta Cemetery in Baicheng City, Jilin Province, China was studied. It is basically conclude that the unearthed bronzes in this cemetery have multiple sources of ore, and one of them is found to contain high radiogenic lead. The age of Shuangta Cemetery overlaps with that of Western Cemetery of Jinggouzi, and they are in a similar geographical location. As human bones unearthed from two sites belong to the same type of people, so lead isotopes of bronzes artifacts unearthed from two sites were compared to determine whether the same ore source was used. The results show that although bronzes from Shuangta Cemetery contain different ore sources, but some use the same (or similar) mineral material sources as those unearthed in the Western Cemetery of Jinggouzi.
