摘　　要：利用X荧光光谱(XRF)、电感耦合等离子发射光谱(ICP-AES)对湖北省襄樊市陈坡战国楚墓出土的部分青铜器残留泥芯进行了主量元素、稀土元素测试分析,并与当地原生土、附近出土时代相近的陶片、黄河中游地区的山西侯马东周陶范及长江流域的典型红土进行了比较分析。结果表明:残留泥芯在主量元素和稀土元素方面与当地土壤、附近出土陶片具有很高的相似性,而与侯马陶范及典型红土有显著差别,说明这批青铜器应为本地铸造而成;研究结果进一步说明,残留泥芯的地球化学示踪可能是利用自然科学手段判断古代青铜器铸造地最有效的方法。The major and rare earth elements in some clay core residues of bronze vessel unearthed from the Chenpo Chu tomb of Warring States Dynasty in Xiangfan city were analyzed by XRF and ICP - AES. The results were compared with those obtained from the local raw soil, pottery fragments unearthed from the local area, and some clay mould unearthed from the Yellow River valley and laterite from the Changjiang river valley at the same period. The results showed that the distribution pattern of major and rare earth elements in the clay core residue were highly consistent with those in the local soil and the pottery fragments unearthed from the vicinity, but were significantly different from those in clay mould in Houma and in typical laterite. This indicated that the bronze vessel was casted locally. The results also suggested that the geochemical tracing of clay core residue might be the most efficient method for identifying the casting place of bronze vessel.
