摘要：Macroscopic examinations and chemical measurements by non destructive pXRF, ICP-OES and ICP-MS have been applied on 10 geological samples collected from the fossiliferous limestone of the Villagreca Unit, outcropping in Nurallao (central Sardinia). The results of this study have allowed to determine the geochemical intra-source variability of the lithic raw material while the mineralogical investigation performed by PXRD on the same geological samples have led to define some technological properties of the limestone. Then, on 13 Eneolithic menhirs coming from the archaeological site of Aiodda-Nurallao (dating back to the 3rd millennium BC) non destructive pXRF measurements and visual observations have been carried out according to conservative limitations. Through the comparison between artifacts and lithological outcrop’s analytical data, the authors have been able to define the geological source of the raw materials employed in megalithic sculptures manufacturing. Basing on the raw material technological properties, it has been possible to record the trend to select soft stones easy to work by prehistoric technologies.
