Abstract

⁵⁷Fe Mössbauer spectroscopy was applied to compositional studies of Fe-containing minerals in two different ordinary chondrites, MIL 07710 (L4) and Y-790272 (H4), collected in Antarctica. For both samples, spectral analysis revealed that there are five quadrupole doublets and two magnetic sextets in the room-temperature spectra, suggesting the presence of olivine (M1 and M2), pyroxene (M1 and M2), a high-spin Fe³⁺ containing phase, antiferromagnetic FeS (troilite), and ferromagnetic Fe-Ni alloy. The large relative area of the oxidized Fe³⁺ phases and the small intensity of the metal phases signify a possible effect of terrestrial weathering especially for Y-790272 (H4).
