AbstractA set of ancient gold jewellery was found in Cádiz (formerly Gadir, south Spain) in tombs dated in Phoenician-Archaic period (VII-VI century BC), and nowadays is exhibited in the local Museum. The production of this strategic area is of great interest for the knowledge of the commercial routes along the Mediterranean Sea at that time. Part of this production has already been analyzed by the authors, finding compositional differences and identifying soldering procedures, thanks to the use of the external microbeam. Absolutely non destructive analysis was performed. For this work we have again employed PIXE spectrometry with 2.2 MeV protons from the 3 MV Pelletron accelerator at the CNA to characterize the metallic alloys and the manufacturing techniques. We have found an unusual composition characterized by around 50 wt.% gold, 50 wt.% silver and some copper, which can be identified as ELECTRUM. Few analytical data of this particular kind of alloy are reported in the bibliography. The study of these objects can help to follow the trade of metals in the Phoenician-colonial period. © 2007 Elsevier B.V. All rights reserved.
