Abstract A comparative study of troilite in bulk ordinary chondrites Farmington L5, Tsarev L5 and Chelyabinsk LL5 was carried out using Mossbauer spectroscopy with a high velocity resolution and two different fitting programs: in the first case the quadrupole interaction was treated as a perturbation to the first order on the nuclear Zeeman levels, whereas in the other case the full static Hamiltonian of the hyperfine interaction (magnetic + quadrupole) was taken into account for the excited… Expand

Characterization of Kemer L4 meteorite using Raman spectroscopy, X-ray diffraction, magnetization measurements and Mössbauer spectroscopy.
TLDR
The fusion crust of Kemer L4 was studied using X-ray diffraction, magnetization measurements and Mössbauer spectroscopy and Magnesioferrite and probably maghemite were found in the fusion crust in addition to other phases observed in the bulk interior. Expand
Variability of Chelyabinsk meteoroid stones studied by Mössbauer spectroscopy and X-ray diffraction.
TLDR
The fusion crust from two fragments, studied by XRD and Mössbauer spectroscopy, experienced a different thermal history during entry, suggesting that the fragments with mixed light and dark lithologies was located deeper inside the initial meteoroid than the fragment with only light lithology, or fragmented less readily.
