Abstract
KNUDSEN et al.1–3 have recently presented evidence from Mossbauer spectroscopy and X-ray diffraction, that an FeNi L10 superlattice exists in the taenite of the Cape York and Toluca meteorites. This superlattice, which had previously only been reported in neutron irradiated specimens4, is thought to have formed during the extremely slow cooling, 1°C Myr−1, of the parent bodies of these meteorites. Here we report briefly on the discovery of the FeNi superlattice in a nickel-rich ataxite, Santa Catharina, and show that in this meteorite the ordering occurred during terrestrial corrosion.
