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