Resumen:
The purpose of this research is to assess the carbon vapor deposition scenario asproposed in the literature for graphite formation in non-magmatic iron meteorites. Forthis aim, graphite occurrence in a sample of the Campo del Cielo Argentinean ironmeteorite was explored through optical and electron microscopy, Ramanspectroscopy, and time-of-flight secondary ion mass spectrometry. From the results,an alternative setup shall be considered for graphite formation, which would provideevidence for understanding the formation of non-magmatic meteorites, still underdiscussion.
