| description | 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.
RESUMEN: Este trabajo se centra en el estudio de un grupo de artefactos metálicos recuperados recientemente durante las excavaciones arqueológicas en Vila do Touro (Portugal Central), es decir, 19 artefactos y una pequeña inclusión metálica incrustada en las paredes de un fragmento de cerámica. Los objetos han sido analizados mediante un espectrómetro de fluorescencia de rayos X para caracterizar la composición elemental de los artefactos metálicos. Se utilizó un microscopio electrónico de barrido con sistema de microanálisis de rayos X y un microscopio óptico para observar y caracterizar químicamente la inclusión metálica en la cerámica. También se analizó el fragmento de un lingote mediante un espectrómetro de masas de plasma acoplado inductivamente multicolector para abordar cuestiones relacionadas con la procedencia de la materia prima. Los resultados revelaron diferentes patrones de composición (cobre puro, bronce binario, es decir, Cu+Sn, bronces con plomo, es decir, Cu+Sn+Pb, y oro), al tiempo que señalaron la región de Ossa Morena (suroeste de la Península Ibérica) como probable fuente del cobre utilizado para producir el lingote. |
