✦ Synopsis
Five fragments of ancient gold objects belonging to Pietroasa ''Clos ßca cu Puii de Aur'' (''The Golden Brood Hen with Its Chickens'') Romanian hoard were analysed using the micro-PIXE (particle induced X-ray emission) technique. The purpose of the study was to gain some more knowledge regarding the metal provenance by determining the presence of PGE (Platinum Group Elements) and other high-temperature melting point trace elements (Ta, Nb, Cr) at a micrometric scale. Ta and Nb inclusions (micrometric areas of composition different from the surroundings) on three samples and Pd inclusions on one sample were found. The measurements led to some conclusions for the possible gold ore sources of Pietroasa treasury: the South-Ural Mountains, Nubia (Sudan) and/or Anatolian deposits and Roman imperial coins.
