Abstract

The present work presents the first results of a detailed archaeometallurgical study, still ongoing, on a group of metallic findings from Moinhos de Golas archaeological site (Montalegre, Portugal), generically attributed to the Protohistory, and previously presented in a paper dealing with its discovery (FONTE et al. 2013). The collection is composed by 35 objects, which include weapons, ornaments and tools, among other objects of a more difficult classification. The archaeometallurgical study involved X-ray radiography, elemental analysis by micro-EDXRF and microstructural observations by optical microscopy. The radiographies revealed some structural heterogeneities in some artefacts and the elemental analysis showed that most of the artefacts were produced in a binary bronze alloy (Cu-Sn), being others made in copper and brass. Microstructures associated with different manufacturing processes were observed, which may involve hammering and annealing cycles with or without finishing operations.
