何郢遗址出土青铜器铜矿料来源的初步研究

本文利用地球化学示踪的方法对何郢遗址出土青铜器的铜矿料来源进行了初步研究.采用ICP-AES测试了样品的微量元素,根据元素的地球化学亲和性,探索其在冶炼过程中的化学行为和再分配规律,从而选出对铜绿山和皖南的铜陵、南陵铜矿具有指示意义的特征元素,作为判断其铜料输出路线的综合判别标志.结合文献和地质资料,可初步认为何郢遗址青铜器的铜矿料来自滁县.

Study of Provenance of Copper Mine Made of the Bronzes Excavated from Heying Sites

This study uses geochemistry tracing to constrain on provenance of bronzes from Heying archaeological site. Tracing ancient copper of bronzes back to its source ore via trace - element analysis must combine quantitative analysis with qualitative analysis. In situ trace - element analysis conducted by Inductively Coupled Plasma Atomic Emission Spectrometer (ICP - AES) confirms sample data of copper ores, copper ingots and slag from the ancient Tonglvshan mining site in Hubei province, Tongling and Nanling mining sites in Anhui province. According to geochemical principals, this study researches into chemical conduct and reallocating law of elements in metallurgical steps on the way from ore to metal. In smelting, some elements almost all run away with slag and some are most enriched in copper metal. We only select those elements enriching in copper metal as tracing elements of copper ore deposits. Based on the documents and geological data, we can draw a preliminary conclusion that the bronzes from Heying site are made of copper metal from copper ore deposits in Chu county.
