Abstract
Samples from the two Ni-rich iron meteorites Santa Catharina and Twin City have been investigated by conventional Mössbauer spectroscopy and by conversion electron Mössbauer spectroscopy. The spectra obtained show that the major components of these two meteorites are an ordered FeNi (∼50%, ∼50%) phase and a paramagnetic Fe−Ni phase with ≤28% Ni.
