Archaeometric Analyses of Transylvanian Metal Artefacts. Case Study: The Scythian Necropolis of Sâncrai (Alba County)

Summary/Abstract: The Scythian necropolis of Sâncrai (Alba County) was investigated in 2016, which led to the discovery of 95 burials (inhumation and cremation). The study of the tombs revealed a rich funerary inventory, composed mainly of ceramic vessels of different shapes and sizes; weapons such as akinakes daggers, spearheads and arrowheads; ornaments including amber beads, kauri shells, kaolin, earrings, loop rings, saltaleoni type bracelets and clothing appliqués; and harness elements, including horsehair and quiver appliqués. The purpose of this paper is to describe the archaeometric analyses of metal pieces recovered from this site.A combination of non-invasive/micro-destructive analytical techniques (optical microscopy, scanning electron microscopy coupled with energy dispersive spectrometry, and Fourier-transform infrared spectroscopy) and statistical methods (cluster analysis, using SPSS Statistics) was used to obtain comprehensive information about the studied metal artefacts. In this respect, 16 metallic samples were investigated to establish the samples’ defects as well as their elemental and molecular composition. Overall, the analytical and statistical analyses show us that the metallic samples can be split into three groups based on composition: iron, copper-tin/bronze and gold-silver. In these groups, samples present a strong correlation, suggesting that they were created using similar minerals.
