钟祥黄土坡墓地出土春秋青铜器的检测分析及相关问题研究

Research on Detection Analysis and Related Problems of the Bronzes in the Spring and Autumn Period Unearthed from Zhongxiang Loess Slope Cemetery

钟祥黄土坡墓地出土青铜器对了解春秋中晚期江汉平原西部的合金技术和金属资源类别有重要意义。黄土坡早期M31铜器含锡量高达20%,稍晚的M35和M4铜器锡含量在15%附近。公元前六世纪前期,钟祥黄土坡、江陵岳山及公安石子滩等地出土青铜器的铅同位素比值基本相同,并与同期汉淮各地青铜器也较为一致,体现楚系青铜器发展成熟时的资源和技术面貌。

The bronze vessels unearthed from Huangtupo Cemetery, Zhongxiang City in Hubei Province, are analyzed and the result is of great significance for the alloying technology and provenance study in western Jianghan Plain dur-ing the 7 th to 6 th century B. C. In the early stage of Huangtupo Cemetery, the tin content of bronze from M31 is up to 20 %, while those of M35 and M4 are around 15 %. In the early 6 th century B. C., the lead isotope ratios of bronzes from Huangtupo( in Zhongxiang City), Yueshan( in Jingzhou City) and Shizitan( in Gong’an County)are approximately the same, and they are consistent with the data of other part of Han and Huai River basin as well.
