Resumen:
Following previous studies [1] on the applications of
Mössbauer spectroscopy to the meteoritic Fe-Ni metal structures,
the present work focus in the study of Fe-Ni alloys in
mesosiderites. The metal from this enigmatic rocks have the
lowest cooling rates yet determined for meteorites.
We are performing a systematic study on several
mesosideritos as follow: Vaca Muerta, Mincy, Crab Orchard,
Estherville and Hainholz. Thin ~500 μm slices are cut from the
metal-rich areas and then polished to thicknesses ~150 μm.μm slices are cut from the
metal-rich areas and then polished to thicknesses ~150 μm.μm.
