IFLScience<\/a> fragt: „How did Bronze Age civilizations manage to forge iron weapons before they had learned how to smelt iron ore?“ Die Antwort ist verbl\u00fcffend: “ It turns out, they had a little bit of help from the cosmos, as many of the iron artifacts from this era appear to have an extraterrestrial origin.“ Der Original-Artikel<\/a> „Bronze Age iron: Meteoritic or not? A chemical strategy.“<\/p>\n

Hier das Resume:
\n\u2022 There has been a controversy about the origin of Bronze Age irons that could be either meteoritic or smelted irons.
\n\u2022 A geochemical approach using Fe:Co:Ni analyses, permits to differentiate terrestrial from extraterrestrial irons.
\n\u2022 Meteoritic irons, Bronze Age iron artifacts, ancient terrestrial irons and lateritic ores enable to validate this approach.
\n\u2022 Modern irons and iron ores are shown to exhibit a different relationship in a Fe:Co:Ni array.
\n\u2022 Iron from the Bronze Age are meteoritic, invalidating speculations about precocious smelting during the Bronze Age.<\/i><\/p>\n
