“…Further, with the development of technique application, the high velocity resolution Mössbauer spectroscopy (high discretization of both the velocity reference signal and the velocity scale in the spectra) demonstrated significant advances in the study of the complicated spectra of various meteorites in order to extract more detailed information. [3][4][5][6][7] Therefore, in the present work we discuss the results of re-examination of the first samples of Dronino oxidation products in comparison with new samples studied with the high velocity resolution Mössbauer spectroscopy.…”

Weathering products of two fragments of Dronino iron ungrouped meteorite found in the wet and drier clay sand were studied using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The products of metal oxidation in the internal and external surface layers were different for both fragments. The weathering products in fragment found in the wet clay sand contain magnetite (Fe3O4), maghemite (-Fe2O3), goethite (-FeOOH) and probably ferrihydrite (5Fe2O3  9H2O) while those in fragment found in drier clay sand contained ferric hydrous oxides (FeOOH) and siderite (FeCO3) mainly. Concretions found near the first fragment contain ferric hydrous oxides (FeOOH) mainly.

“…Mössbauer spectroscopy was successfully used to distinguish M1 and M2 sites in pure synthetic olivines [1][2][3]. Recently, we demonstrated new possibilities of Mössbauer spectroscopy with a high velocity resolution in the study of ordinary chondrites and other meteorites [4][5][6]. In particular, the differences of hyperfine parameters for 57 Fe in the M1 and M2 sites of olivines in different bulk ordinary chondrites were respectively revealed for the first time.…”

“…4. Based on our previous data for olivine study [4][5][6][11][12][13], we related the component 1 with the larger ǻE Q and S values to 57 Fe in the M1 sites while the component 2 with the smaller ǻE Q and S values was related to 57 Fe in the M2 sites in olivine. The component 3 had parameters which we cannot relate to any impurity.…”

Proc. 1622, 24 (2014) Abstract. Study of olivine from Omolon and Seymchan meteorites was performed using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. X-ray diffraction patterns were measured at room temperature while Mössbauer spectra were measured at 295 and 90 K. The orthorhombic crystal lattice parameters were evaluated for olivine from Omolon and Seymchan. These parameters appeared to be different for olivines from both meteorites. Mössbauer spectral components related to 57 Fe in crystallographically non-equivalent sites M1 and M2 in both olivines were determined and its Mössbauer hyperfine parameters were evaluated. Some differences in the tendencies of temperature dependence of spectral parameters and small variations of 57 Fe quadrupole splitting in both M1 and M2 sites of olivines from Omolon and Seymchan were found. On the basis of Mössbauer parameters and chemical data, the temperatures of equilibrium cation distribution were evaluated for both olivines.

a b s t r a c tIron oxide nanoparticles, probably magnetite, as-prepared and dispersed in Copaiba oil were studied by Mössbauer spectroscopy using two different spectrometers: with a low velocity resolution (512 channels) for measurements at 295 and 21 K and with a high velocity resolution (4096 channels) for measurements at 295 and 90 K. The fitting of all measured spectra demonstrated that usual models applied to fit Möss-bauer spectra of magnetite and maghemite particles were not suitable. Therefore, the recorded spectra were fitted using a large number of spectral components on the basis of better quality of the fit and linearity of differential spectra. The number of components obtained for the better fit appeared to be different for spectra measured with a low and a high velocity resolution. However, these results demonstrated differences of Mössbauer parameters for iron oxide nanoparticles as-prepared and dispersed in Copaiba oil at applied temperatures. The effect of Copaiba oil molecules on Mössbauer parameters may be a result of the interactions of polar molecules such as kaurinic acid with nanoparticles' surface.
