Abstract:
Fifteen fragments of H, L and LL ordinary chondrites were studied using Mossbauer spectroscopy with a high velocity resolution at 295 K. A new approach to fit troilite magnetic sextet using simulation of the full static Hamiltonian was applied that decreased spectra misfits. This approach permitted to obtain more correct and reliable parameters for the minor spectral components. Small variations in the Fe-57 hyperfine parameters were revealed for the M1 and M2 sites in both olivine and orthopyroxene as well as for alpha-Fe(Ni, Co), alpha(2)-Fe(Ni, Co) and gamma-Fe(Ni, Co) phases in different ordinary chondrites. Some Mossbauer parameters showed the possibility to distinguish ordinary chondrites from H, L and LL groups that may be useful for their systematics.
