“…In early 2000 a Mössbauer group from India started systematic studies on the possibility of the application of Mössbauer spectroscopy to the classification of ordinary chondrites [2][3][4]. Using different types of plots such as "areas for metallic phases vs. areas for nonmetallic phases", "areas for metallic phases vs. areas for silicate phases" and "areas for pyroxene vs. areas for olivine" this group determined regions for H, L and LL types of the meteorites.…”

The aim of our studies was to check the usefulness of Mössbauer spectroscopy for preliminary classification of ordinary chondrites. Mössbauer spectra of 50 samples of ordinary chondrites (type LL, L and H) obtained at room temperature were analyzed. 35 Mössbauer spectra were obtained in our laboratory, the other spectra were taken from the literature. The conclusion of our study was, that the most useful way for the preliminary classification of the ordinary chondrites is the application of two types of plots based on the data obtained by Mössbauer spectroscopy. One type of these plots is a linear plot which was used for the identification of the samples which are unrepresentative. The second type of these plots is a plot of "spectral area of the olivine" vs "spectral area of the metallic phase". This last one was used for the identification of two unknown meteorites.

“…However, investigations of some meteorites samples using Mössbauer spectroscopy with a high velocity resolution demonstrated new results in revealing of spectral components which cannot be obtained from the low velocity resolution Mössbauer spectra [12,[27][28][29][30]. For instance, in the study of ordinary chondrites it was possible to fit complicated Mössbauer spectra using components related to the crystallographically non-equivalent M1 and M2 sites occupied by both Fe 2+ and Mg 2+ ions in both pyroxene (Fe,Mg)SiO 3 and olivine (Fe,Mg) 2 SiO 4 while in the low velocity resolution spectra this was not possible (see comparison of Mössbauer spectra of ordinary chondrites measured in [31] with a low velocity resolution and with a high velocity resolution (this work) in Fig. 7).…”

a b s t r a c tThe methodological principles of velocity resolution as additional characteristic of the quality of both Mössbauer spectrometer velocity driving system and Mössbauer spectrum were briefly considered. Significantly better quality of Mössbauer spectra measured with a high velocity resolution in comparison with those measured with a low velocity resolution was demonstrated. The main advances of recent studies of iron containing biomolecules, pharmaceutical products, meteorite samples and nanoparticles using Mössbauer spectroscopy with a high velocity resolution were considered and advantages of this technique were shown.

Mössbauer studies of Soltmany and Shisr 176 meteorites – comparison with other ordinary chondrites

Two ordinary chondrites type L6: Soltmany and Shisr 176, were recently investigated in our laboratory. The distribution of iron in the 4 main iron bearing mineral phases (olivine, pyroxene, kamacite and troilite) determined by Mössbauer spectroscopy in Soltmany and Shisr 176 meteorites was very different from that in the Baszkowka meteorite (type L5). To explain the cause of this difference, a comparison of the distribution of iron among the main mineral phases present in other type L and H meteorites was performed. Our studies have shown that the Baszkowka meteorite is not a good point of reference for Soltmany and Shisr 176 meteorites.
