皖南沿江地区部分出土青铜器的铜矿料来源初步研究

根据要想追溯青铜器铜矿料来源，必须先了解古铜矿及其冶炼金属产物的微量元素和同位素特征，研究其输出方向这一思路，以前期提出的以较高含量的Se、Te、Ni(Co／Ni大多小于1)、Ag、Au等及相对低含量的Sb、Bi、Mo等作为安徽铜陵等地古铜矿冶炼产物一铜锭产地的特征指示元素为综合判别标志，用等离子发射光谱仪对皖南沿江地区出土的部分青铜器进行多元素分析。结果表明，样品Tc2007、Tc2005、fc12所用铜料不大可能来自铜陵地区，其余样品可能来自当地。鼎、(虚瓦)等大件样品可能在其它地区铸造后传人本地。研究结果说明，利用微量元素判断青铜器铜矿料来源是可行的。

Study on the copper material sources of some bronzes unearthed in Southern Anhui along Changjiang River

In order to study the provenance of bronzes and their mineral sources, indicator elements of ancient copper ore and their smelted metallic products must first be known. With higher contents Se, Te, Ni(mostly, Co/Ni less than 1), Au, Ag and lower contents Sb, Bi, Mo as indicator elements of ancient copper ingots of Tongling site, copper mineral sources of some unearthed bronzes in Southern Anhui along Changjiang river have been determined. Some bronzes used Tongling's copper material, and some (such as samples Tc2007, Tc2005, and Fcl2) from other sites. Large vessels, as Ding and Li, were probably cast in some other place, and then introduced to this place. The work has shown that it is feasible to probe into the copper material sources of bronze - making metals by using trace elements.
