Chemical analyses of pre and proto-historic gold artifacts, using EDXRF and PIXE, are presented. Fragments of gold leaves from chalcolithic settlements, two gold rivets from a Bronze Age knife and a gold Iron Age torc are among artifacts analysed at the Nuclear and Technologic Institute (Sacavém) during different archaeometric (archaeometallurgy) research programs. If the chemical compositions of the first ones point out to the use of native gold and the rivets are made of electrum, also native, with a composition very similar to that one from an artifact from El Argar Bronze Age found at Almeria (South- eastern Spain), the analysed torc, found near Chaves, presents a composition - 72-73% Au; 26-27% Ag; 1-2% Cu - that falls within the main ...
