You may already be surprised to hear there are iron objects dating back to the Bronze Age, but their meteorite origin is even more astonishing. Though meteorites had already been recognized as one source of this metal, the scientific community couldn't determine whether they accounted for most or simply a few Bronze Age iron artifacts. Albert Jambon, as part of his work at the Institut de minéralogie, de physique des matériaux et de cosmochimie (CNRS / UPMC / IRD / Muséum national d'Histoire naturelle),1 has demonstrated that iron used during the Bronze Age is always meteoric and he explained how this practice was abandoned during the Iron Age. His work is published in the December 2017 issue of the Journal of Archaeological Science.
