“…Therefore, it is not possible to reproduce extraterrestrial Fe-Ni-Co alloys in the terrestrial conditions while some features of meteorite metallic iron may be useful for new alloys development. Mössbauer spectroscopy is a useful tool for study iron meteorites (see, for instance, [2][3][4][5]). Therefore, we have applied Mössbauer spectroscopy to study some iron meteorites in order to evaluate the relationship of the hyperfine parameters and metal phases in meteorites with variations in Ni concentration [6,7].…”

A comparative study of Sikhote-Alin IIAB, Anyujskij IIAB, Aliskerovo IIIE-an and Sterlitamak IIIAB iron meteorites was carried out using Mössbauer spectroscopy with a high velocity resolution as well as using metallography, scanning electron microscopy with energy dispersive spectroscopy and X-ray diffraction. Different numbers of spectral components were found in the Mössbauer spectra of Sikhote-Alin IIAB and Anyujskij IIAB and in the spectra of Aliskerovo IIIE-an and Sterlitamak IIIAB iron meteorites. The values of hyperfine field at the 57 Fe nuclei obtained for spectral components were related to α-Fe(Ni, Co), α 2 -Fe(Ni, Co) and γ -Fe(Ni, Co) phases with variations in Ni concentration.

“…We report studies on two iron meteorites, one of them belonging to the shower find of Campo del Cielo, and the other from an unknown find; this latter unregistered meteorite was named by us as "Find 1". In the Campo del Cielo find, a region belonging to the province of Chaco and Santiago del Estero, Argentina, there are samples characterized as octahedrites and others as hexahedrites [20]. This heterogeneity in the shower find was first proposed by Villar [21], and is the reason of our study on that specific meteorite.…”

This review presents studies on iron meteorites (Campo del Cielo fall and an unregistered iron meteorite), an unregistered stony meteorite from Northwest Africa, and 13 tektites from the American, European, and Australasian strewn fields. The main experimental technique used in the studies was Mössbauer spectroscopy, both in transmission and backscattering geometries. For the latter, a MIMOS II spectrometer was used. Additionally, optical and scanning electron microscopies and X-ray diffraction were used. In the studied iron meteorites, kamacite is found as the main mineral. Campo del Cielo meteorite exhibits Widmanstätten patterns and schreibersite inclusions. The unregistered iron meteorite has Neumann lines and schreibersite inclusions. We have assigned Campo del Cielo as an octahedrite and the unregistered iron meteorite as a hexahedrite. The unregistered stony meteorite is composed mainly of iron-free silicates; at 4.2 K, the spectrum indicates maghemite and 1% troilite. The Cambodian tektite appeared individualized from other australasites, unlike the moldavite, which tends to cluster with them. Our analyses do not allow dismissing doubts on the provenance of tibetanites. The Fe3+/Fe2+ ratio was found to be higher for Muong Nong-type tektites than for splash-form tektites, as expected from their morphology and solidification from melt at lower temperature.

“…A similar study was done for the interior and surface of hexahedrite from the del Cielo meteorite shower in [72] (the name of this meteorite is unknown, whil were many registered iron meteorites found from this shower). This meteorite con 94.6 wt.% Fe and 5.4 wt.% Ni.…”

Applications of Mössbauer Spectroscopy in Meteoritical and Planetary Science, Part II: Differentiated Meteorites, Moon, and Mars

Mössbauer (nuclear γ-resonance) spectroscopy is a powerful technique that is actively used in various fields, from physics and chemistry to biology and medicine. Rudolf L. Mössbauer, who observed nuclear γ-resonance and published his results in 1958, received a Nobel Prize in physics in 1961 for this discovery. The 57Fe is the most widely used nucleus in Mössbauer spectroscopy. Therefore, a large variety of compounds containing iron can be studied by Mössbauer spectroscopy. It is well known that planetary matter contains various iron-bearing phases and minerals. Therefore, the extraterrestrial material from different meteorites, asteroids, and planets can be studied using 57Fe Mössbauer spectroscopy as additional powerful technique. Two parts of this review consider the results of more than 50 years of experience of Mössbauer spectroscopy applied for the studies of various meteorites, soils, and rocks from the Moon and recent investigation of the Mars surface using two rovers equipped with miniaturized Mössbauer spectrometers. Part I will discuss known results on Mössbauer spectroscopy of undifferentiated meteorites, which are the most primitive and formed with the solar system.
