摘要
本研究通过对盘龙城遗址小嘴出土铜器、铜块和浮渣的微量元素与铅同位素比值进行测试,探讨了小嘴金属物料的产源问题。微量元素测试结果显示小嘴样品的银、铋含量较高,与以往测试的盘龙城铜器存在差异。铅同位素分析显示样品中有5件含有高放铅,另外4件的206Pb/204Pb在16.5左右的低比值区域。过往研究显示这类低比值物料的产源应在中国北方,且主要发现在二里头四期至二里岗下层阶段铜器中。小嘴样品的整体年代为二里岗上层阶段,推测盘龙城铸铜活动中可能重熔了部分来自北方的早期铜器或利用了早期遗留的物料。低比值铅与高放铅相互混合则形成了以往认为具有盘龙城本地特征的中间比值组铜器。由此可见,来自长江中游地区以外的金属物料在盘龙城铜器生产中占有重要地位。
The trace element and lead isotope analyses were conducted for bronze fragments,artifact pieces and dross excavated from the site of Xiaozui at Panlongcheng to provenance their metal materials.The trace elements analysis revealed elevated Bi and Ag contents in Xiaozui samples in comparison with Panlongcheng bronze vessels characterized in previous studies.Lead isotope analysis shows that five samples contain highly radiogenic lead while four samples have 206Pb/204Pb ratio of around 16.5.The provenance of this less radiogenic material was probably in North China and mainly identified in the Erlitou IV to the Lower Erligang Bronze artifacts.The Xiaozui samples were dated to the Upper Erligang period and therefore speculated that the recycled early bronze artifacts or raw materials were involved in the bronze production at Panlongcheng.The artifacts featured with intermediate lead isotope ratio were likely the mixture of less radiogenic and highly radiogenic materials.In general,the exotic materials originating out of the Middle Range of the Yangtze River valley play an essential role in bronze production at Panlongcheng.
