Scattering Mössbauer studies of weathered and unweathered Mexican iron meteorites

Non-destructive Mössbauer spectra (MS) of a series of nine Mexican iron meteorites belonging to the collection of the Instituto de Geología of the Universidad Nacional Autónoma de México (IG-UNAM) were obtained by 90º γ-ray scattering. We divided the set of nine meteorites in two groups: The first group shows complex spectra of iron oxides mixed with a paramagnetic phase; their spectra and Mössbauer parameters have noticeable differences. The spectra of the second group are quite similar and characteristic of Fe-Ni alloys.
