Abstract
Even if the lead isotope results are same, the significance of the lead isotopic signature is quite different for the provenance study of the Chinese bronzes. The published data show that the radiogenic lead signatures in the unalloyed copper and the Yin-Shang bronzes with the low lead content are contributed by the copper deposits, while those of the South Africa and Zimbabwe bronzes with highly radiogenic lead were contributed by tin deposits. Combined with the results of lead isotope analysis by LA-MC-ICP-MS and the recent archeological discoveries, it was possible that for the Yin-Shang bronzes with highly radiogenic lead contents, the copper material was derived from Zhongtiao Mountain copper deposits, while the lead material from Huojiagou and Zhenggou in the northern margin of North China Craton, but we prefer that the lead materials were from the southern margin of the North China Craton.
