This study first publishes lead isotope data of bronze vessels from Central China in Western Han Dynasty and attempts to find out the lead ores circulation of this time by taking bronzes from the Gejiagou site (Nanyang City, Henan Province) as an example. The elemental concentrations suggest the lead should be introduced on purpose and indicate the provenance information of lead ores. All the lead isotope ratios conform to the characteristics of common lead and most of them are similar to Nanyang local lead ores. The lead of another two bronzes, NY9 and NY13, should be imported from southern China. Combined with the historical background of early Western Han Dynasty, the wider range of the lead ore circulation may be an indicator for, as the loose policy, economic prosperity and transportation improvement.
本研究首次公布了中国西汉时期青铜器的铅同位素数据，并以河南南阳地区鸽子沟遗址出土的青铜器为例，试图通过这些青铜器找出当时的铅矿流通情况。元素浓度表明，铅是有目的引入的，表明了铅矿的产地信息。所有的铅同位素比值都符合普通铅的特征，而且大多数与南阳当地的铅矿相似。另外两件青铜器 NY9 和 NY13 的铅应该是从中国南方进口的。结合西汉早期的历史背景，铅矿流通范围的扩大可能是政策宽松、经济繁荣和交通改善的一个指标。
