内蒙古林西县井沟子西区出土青铜器的铅同位素分析

Lead Isotope Analysis of Bronze from West Cemetery of Jinggouzi Site of Linxi of Inner Mongolia

研究了井沟子西区墓地青铜器铅同位素组成情况,并与遗址附近的林西大井古铜矿遗址、代黄山铜冶炼遗址、代黄山西侧现代铜矿铅同位素组成情况进行了比较。结果表明,代表井沟子西区墓地青铜器主体的15个Cu-Sn-Pb合金样品与大井古铜矿遗址、代黄山冶炼遗址、代黄山西侧现代铜矿的铅同位素组成差异较大。认为井沟子西区墓地主体青铜器的矿料不是来源于大井古铜矿遗址和代黄山西侧的现代铜矿,也不是在代黄山冶炼遗址冶炼的。

This article researches the situation of Pb isotopic composition in the bronzes from the cemetery in the west of Jinggouzi. The result was compared with the sites nearby,such as the ancient copper mine in Linxidajing,copper smelting site in Daihuangshan mountain and modern copper mine in the west of Daihuangshan mountain. And there are quite differences on the Pb isotopic composition in the15 Cu-Sn-Pb alloy samples from Jinggouzi compared with the other sites. So we can make a conclusion that the mineral source of the brcnzes from Jinggouzi was not from the ancient copper mine in Linxidajing,not from the copper smelting site in Daihuangshan mountain,not from the modern copper mine in the west of Daihuangshan mountain.
