Abstract

This paper focuses on the study of a group of metal artefacts recently recovered during the archaeological excavations in Vila do Touro (Central Portugal), i.e., 19 artefacts and a small metallic inclusion embedded in a pottery sherd. The objects have been analysed by an X-Ray Fluorescence spectrometer to characterise the elemental composition of metal artefacts. A Scanning Electron Microscope with X-ray Microanalysis System and an optical microscope were used to observe and chemically characterise the metal inclusion in the pottery. The fragment of an ingot was also analysed by a multicollector Inductively coupled plasma mass spectrometer to address issues bound to the provenance of raw material. The results revealed different compositional patterns (pure copper, binary bronze, i.e., Cu+Sn, leaded bronzes, i.e., Cu+Sn+Pb, and gold), while pointing out the Ossa Morena region (Southwest of the Iberian Peninsula) as likely source of copper used to produce the ingot.
葡萄牙中部青铜时代晚期/铁器时代早期冶金的新数据。Vila do Touro的贡献(萨布加尔、瓜尔达)
本文重点研究了最近在葡萄牙中部的Vila do Touro考古发掘中发现的一组金属文物,即19件文物和一小块嵌在陶器碎片中的金属夹杂物。用x射线荧光光谱仪对这些物体进行了分析,以确定金属制品的元素组成。利用扫描电子显微镜、x射线显微分析系统和光学显微镜对陶器中的金属夹杂物进行了观察和化学表征。用多收集器电感耦合等离子体质谱仪对铸锭碎片进行了分析,以解决与原材料来源有关的问题。结果显示了不同的成分模式(纯铜,二元青铜,即Cu+Sn,含铅青铜,即Cu+Sn+Pb和金),同时指出Ossa Morena地区(伊比利亚半岛西南部)可能是用于生产铸锭的铜的来源。
