Déterminer les zones d’approvisionnement en cuivre archéologique

Abstract : The Oxalid database gathers isotopic analyzes on both ores and (semi)finished products dating mainly from the Bronze Age. This study presents the application of multivariate statistical processing to this shared database. A pre-processing is done first in order to select the ore data on their relevancy. Five isotopic ratios defining the isotopic signature of these ores are processed using multivariate statistics (AHC, DFA). Population groups are made according to the analytical data and confronted with the location of the analyzed samples. Once the isotopic signature of the copper deposits has been defined, the provenance determination tool is tested. Ingots whose ore deposit of origin is known are used for this purpose. (Ingots data are also present in the Oxalid database). The link between minerals and objects (semi-finished) is thus validated. It then becomes possible to propose a provenance to the cuprous archaeological artefacts for which the isotopic signature has been determined.
