Abstract:

The results of the study of various meteorites (iron, ordinary chondrites and carbonaceous chondrites) by Mossbauer spectroscopy with high velocity resolution at room temperature are presented. Different Fe(Ni,Co) phases in a metal component and spectral components that are related to structurally nonequivalent M1 and M2 positions in olivine and pyroxene have been revealed in the spectra of eleven ordinary chondrites as a result of a velocity-resolution increase. The spectra of two types of iron phosphides (rhabdite and schreibersite) extracted from the Sikhote-Alin iron meteorite have been measured for the first time, a difference in the magnetic hyperfine structure of Fe-57 nuclei in the rhabdite and the schreibersite has been observed, and a preliminary estimation of their parameters has been made. The measured-for-the-first-time Mossbauer CH/CB spectra of the Isheevo chondrite demonstrated some differences between the internal and surface parts of the meteorite. The parameters obtained allowed us to detect the presence of three Fe(Ni,Co) phases in the Isheevo metal.
