安徽枞阳出土西周至战国时期青铜器的矿料来源研究

摘要

Trace elements of bronze vessels,which are from Zongyang County,Anhui Province and dated from the Western Zhou Dynasty to Warring States Period,and copper prills in the slag from Tangjiadun Site,were analyzed with LA-ICP-MS to deter-mine their copper ores sources.Results show that contents of elements Co,As,Sb,Ag and Bi,et al.in the copper prills of slags from Tangjiadun site are high,which are different from the elements characteristics of smelted copper metal from Tongling and Tonglvshan site of mining and smelting.Copper ores sources of the bronze vessels from Zongyang County are stable from the Western Zhou Dynasty to Warring States Period.The copper ores mainly come from the vicinity around Tangjiadun site in Zongyang County and a small proportion is from Tongling area in the south of the Yangtze River.It is feasible that LA-ICP-MS can be used to determine trace elements in the ancient bronze vessel and copper prills in the slag from the site of mining and smel-ting,which provides a in situ nondestructive analysis technology for bronze vessel analysis and has important potential applica-tions in the study on copper ores sources of ancient bronze vessels.%采用激光剥蚀电感耦合等离子体质谱(LA-ICP-MS),对枞阳境内出土西周至战国时期青铜器和汤家墩遗址出土炼渣中的铜颗粒进行微量元素原位无损分析,以探讨枞阳县境内出土青铜器的铜矿来源.结果表明,枞阳汤家墩遗址冶炼铜金属颗粒中的Co,As,Sb,Ag和Bi等元素含量较高,其微量元素特征不同于铜陵和铜绿山的冶炼金属铜;从西周至战国时期,枞阳青铜器所用铜矿来源比较稳定,主要来自汤家墩遗址周边的枞阳县境内,有少量器物的铜矿可能来自长江以南的铜陵地区;LA-ICP-MS可用于青铜器和古铜矿冶遗址炼渣中所夹杂铜颗粒的微量元素原位无损分析,从而为利用炼渣探讨古矿冶遗址冶炼金属产品的微量元素特征奠定了基础,对探讨三代青铜器的矿料来源研究具有重要的应用价值.
