The objects were analysed by XRF, μPIXE, and SEM-EDS, and the composition of the gold alloys from both burials are discussed and compared with published data from the same periods. PGE inclusions were observed in almost all jewellery , indicating the use of alluvial gold. The analysis of some joins has confirmed the use of hardsoldering, with solders obtained by addition of Cu to the base alloy. %G English %2 https://cnrs.hal.science/hal-03855458/document %2 https://cnrs.hal.science/hal-03855458/file/Troalen%20et%20al%202022%20NEW.pdf %L hal-03855458 %U https://cnrs.hal.science/hal-03855458 %~ CNRS %~ MONARIS %~ INC-CNRS %~ SORBONNE-UNIVERSITE %~ SORBONNE-UNIV %~ SU-SCIENCES %~ SU-TI %~ ALLIANCE-SU %~ TEST2-HALCNRS %~ CHIMIE-SU
