“…Another option of precise measurements was developed in the case of so-called Mössbauer spectroscopy with a high velocity resolution, i.e., with a higher discretization of the velocity reference signal (up to 2 12 ) than that in conventional spectrometers (up to 2 9 ) (see [24,25]). This method is not so fast but very precise and sensitive that demonstrates some important advances in the study of meteorites (for review see [26][27][28][29][30]). In the present review, which was divided in two parts: this Part I and the next Part II [31], we will consider the main results of various meteorites and planetary materials investigations by 57 Fe Mössbauer spectroscopy known up to now.…”

Mössbauer (nuclear γ-resonance) spectroscopy is a powerful technique which 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, got a Nobel Prize in physics in 1961 for this discovery. 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 an 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 a recent investigation of the Martian surface using two rovers equipped with miniaturized Mössbauer spectrometers. Part I considered the results of Mössbauer spectroscopy of undifferentiated meteorites. Part II discusses the results of Mössbauer spectroscopy of differentiated meteorites formed in asteroids and protoplanets due to matter differentiation, as well as Lunar and Martian matter.

“…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.

“…Iron is the most stable element produced by nuclear reactions at ambient pressure, and one of the most abundant elements in the Earth. Thus, magneto-structural transformations and high-pressure states in iron attract enormous interest, especially in geophysics because iron is a primary constituent of the Earth's core, 29−164 many meteorites, [164][165][166][167][168][169][170][171][172][173] and, due to its properties and availability, most steels. 174 At low pressure P and temperature T , the α-phase of iron is a ferromagnet (FM) with the body-centered cubic (bcc) structure.…”

Coexistence pressure for a martensitic transformation from theory and experiment: Revisiting the bcc-hcp transition of iron under pressure

The coexistence pressure of two phases is a well-defined point at fixed temperature. In experiment, however, due to non-hydrostatic stresses and a stress-dependent potential energy barrier, different measurements yield different ranges of pressure with a hysteresis. Accounting for these effects, we propose an inequality for comparison of the theoretical value to a plurality of measured intervals. We revisit decades of pressure experiments on the bcc ↔ hcp transformations in iron, which are sensitive to non-hydrostatic conditions and sample size. From electronic-structure calculations, we find a bcc ↔ hcp coexistence pressure of 8.4 GPa. We construct the equation of state for competing phases under hydrostatic pressure, compare to experiments and other calculations, and address the observed pressure hysteresis and range of onset pressures of the nucleating phase.
