| 摘 要： | 在总结前人对商周遗址中青铜器研究的基础上,通过对成都金沙遗址出土青铜器的铅同位素和主要金属元素含量的测定,分析讨论了金沙青铜器的化学特征及可能的矿质来源。通过对测定结果的分析认为：青铜器的冶炼过程中人为进行铜铅锡含量配比的迹象并不明显,更多体现出直接利用多金属矿的结果;金沙遗址中青铜器的铅同位素值大部分异常高,表现出N（206Pb）/N（204Pb）大于20。根据区域地质资料和前人对多金属矿床的研究结果,认为金沙青铜器的铜矿石极有可能来自于距离较近的会理拉拉厂铜矿。

| Abstract: | On the basis of summarizing formers＇ results on bronze wares at some sites of Shang and Zhou dynasties,Pb isotopes and main metal elements of bronze wares at Jinsha Site in Chengdu were measured,and characters and possible ore sources of bronze wares at Jinsha Site were discussed.The result showed that there was no evidence that contents of Cu,Pb and Sn were artificially controlled while smelting bronze wares;bronze wares at most sites of Shang and Zhou dynasties were possibly smelted with multi-metal ores;the values of Pb isotopes of bronze wares at Jinsha Site were mostly high,and N（206Pb）/N（204Pb） was higher than 20.According to geology data and formers＇ results on multi-metal mineral deposits,Cu ores of bronze wares at Jinsha Site could be from Lalachang Cu deposits in Huili county,which is not far away from Jinsha Site. |
