In order to determine the trace element chemical signature from the ore to the slag inclusion of the ferrous artefacts in the Pays de Bray (France), 143 samples were analysed by INAA, ICP-MS and LA-ICP-MS. Results show that, for geochemical reasons, some elements must be avoided to determine the chemical signature. Nevertheless, a main part of elements initially present in the ore allows to determine the chemical signature of the Pays de Bray. This signature is significantly different from the one of other regions and can be use for further studies about the commercialisation of Pays de bray ferrous artefacts in the neighbouring regions.
