摘要
陕西省淳化县枣树沟脑遗址出土一批西周黄金制品,为研究其成份特征和制作工艺,利用超景深显微镜、金相显微镜对其中4件金器的表面和内部组织进行观察,结果显示其有热锻及退火处理等工艺特点;采用扫描电镜显微能谱仪、电子探针检测分析,发现其为金银合金且存在铂族元素富集的现象,进而推测其矿料来源可能与南秦岭黑色岩系中的金矿床具有一定联系。渭河流域的西周金器工艺和金矿料来源分析结果暗示,该地区先民可能已掌握了黄金开采和器物制作技术。
This paper presents the analytical results of gold wares yielded from the Western Zhou site at Zaoshugounao,Chunhua county,Shaanxi.In order to understand the manufacturing techniques,a total of four gold wares were subjected to ultra-depth field microscopic and metallographic analyses.Results show that these objects were made by hot forging and subjected to annealing treatment.Through SEM-EDS and EMPA examination,it is found that these gold wares were made of gold and silver alloys.In addition,the results illustrate that there is an enrichment phenomenon of platinum group elements,suggesting that the ore resource was related to the gold deposit in the black argillaceous rock series from the south Qinling mountains.The manufacturing techniques and potential provenance of ore source together indicate that ancient communities in the Wei River valley might have been knowledgeable in gold mining and object manufacturing.
