Resumen:
The purpose of this research is to assess the carbon vapor deposition scenario as proposed in the literature for graphite formation innon-magmatic iron meteorites. For this aim, graphite occurrence in a sample of the Campo del Cielo Argentinean iron meteorite wasexplored through optical and electron microscopy, Raman spectroscopy, and time-of-flight secondary ion mass spectrometry. From theresults, an alternative setup shall be considered for graphite formation, which would provide evidence for understanding the formationof non-magmatic meteorites, still under discussion
