“…The fragment also showed a very low metal content (of ~1.7%). The obtained Mössbauer parameters were in agreement with previously published data for ordinary chondrites (see, for instance, [4][5][6][7][8][9][10][11][12][13]). In the present work, we consider the results of the study of another fragment of Chelyabinsk LL5 meteorite with a light lithology and its fusion crust carried out using Mössbauer spectroscopy with a high velocity resolution.…”

Abstract. Study of Chelyabinsk LL5 ordinary chondrite fragment with a light lithology and its fusion crust, fallen on February 15, 2013, in Russian Federation, was carried out using Mössbauer spectroscopy with a high velocity resolution. The Mössbauer spectra of the internal matter and fusion crust were fitted and all components were related to iron-bearing phases such as olivine, pyroxene, troilite, Fe-Ni-Co alloy, and chromite in the internal matter and olivine, pyroxene, troilite, Fe-Ni-Co alloy, and magnesioferrite in the fusion crust. A comparison of the content of different phases in the internal matter and in the fusion crust of this fragment showed that ferric compounds resulted from olivine, pyroxene, and troilite combustion in the atmosphere.Keywords: Chelyabinsk LL5 ordinary chondrite, fragment with a light lithology, fusion crust, Mössbauer spectroscopy with a high velocity resolution.

“…These groups contain a weight percentage of total Fe from 25 to 28%, from 20 to 25%, and from 19 to 22%, as well as different ranges of fayalite (Fa): 16-20 mol%, 22-26 mol%, and 27-31 mol% for H, L, and LL groups, respectively (Dodd 1981). Therefore, Mössbauer spectroscopy was applied in various studies of ordinary chondrites (for instance, Sprenkel-Segel and Hanna 1964;Danon et al 1979;de Oliveira et al 1988;Ortalli and Pedrazzi 1990;Gismelseed et al 1994Gismelseed et al , 2005Zhang et al 1994;Bland et al 1996Bland et al , 1998aBland et al , 1998bAbdu and Ericsson 1997;Dunlap 1997;Scorzelli et al 1998;Grandjean et al 1998;Calogero et al 1999;Paliwal et al 2000;Verma et al 2002Verma et al , 2003Verma et al , 2004Menzies et al 2005;Al-Rawas et al 2007).…”

Abstract-An improvement in the velocity resolution and quality of Mössbauer spectra has been applied to a group of ordinary chondrites. This improvement permitted us to carry out a more detailed study of the iron bearing phases in these samples than has previously been possible. Mössbauer spectra of 11 ordinary chondrites of L and H chemical groups were measured using 4096 channels and presented for further analysis in 1024 channels. Subspectra of the metal grains of several chondrites demonstrated the presence of at least two magnetic sextets related to the main Fe(Ni, Co) phases. Moreover, Mössbauer study of extracted metal grains from Tsarev L5 revealed three sextets and one singlet spectral components related to various α-Fe(Ni, Co), α′-Fe(Ni, Co), α 2 -Fe(Ni, Co), and γ-Fe(Ni, Co) phases. Each subspectrum of olivine and pyroxene in Mössbauer spectra of ordinary chondrites was fitted by superposition of two quadrupole doublets related to M1 and M2 sites in minerals for the first time. An analysis of relative areas and Mössbauer hyperfine parameters was performed and some differences for L and H chondrites as well as for M1 and M2 sites were observed. Mössbauer parameters of troilite and oxidized iron were analyzed. In contrast to a previous study with 512-channel spectra, the presence of oxidized iron was found in all chondrites.

“…Recently, we have explored Mössbauer spectroscopy's potential in the field of meteorite classification. (Verma et al 2002;Tripathi et al 2000;Paliwal et al 2000). Each broad class has been established to have its own characteristic Mössbauer pattern, and a fingerprint analysis scheme can be developed using this technique.…”

Abstract-Mössbauer absorption areas corresponding to 57 Fe in olivine, pyroxene, troilite, and the metallic phase in ordinary chondrites are shown to exhibit certain systematic behaviors. H chondrites occupy 2 distinct regions on the plot of metallic phase absorption area versus silicate absorption area, while L/LL chondrites fall in a separate region. Similar separation is also observed when pyroxene absorption area is plotted against olivine absorption area. The one-dimensional plot for the ratio of olivine area to pyroxene area separates L and LL chondrites. Based on these systematics, a newly fallen meteorite at Jodhpur, India is suggested to be an LL chondrite.
