“…These compounds were found in the weathered ordinary chondrite Mössbauer spectra shown above. Some other examples of the Mössbauer spectra of weathered ordinary chondrites Camel Donga 007 L5, Gunnadorah 002 L5 and Lynch 001 L5-6 measured with a low velocity resolution in [118,123] and Gandom Beryan 008 H5 measured with a high velocity resolution in [124] are shown in Figure 46.…”

“…However, to determine ferric compounds exactly, the low temperature measurements are required because paramagnetic compounds undergone magnetic phase transitions as well as distinguishing of the different ferric compounds in the magnetic states is better due to different behavior (see, e.g., [64,118,[126][127][128][129]). [118,123,124].…”

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.

“…The phase composition of the investigated chondrites was estimated with XRD, SEM, EDX, and M€ ossbauer spectroscopy. For each sample, we successively added phases reported by , Petrova et al (2019), andIzawa et al (2010) starting from the most abundant olivine and pyroxene until best-fit quality was achieved. Figure 2 reports experimental XRD patterns along with the fit and residual difference.…”

Micro X-ray fluorescence (XRF) analysis, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and M€ ossbauer and X-ray absorption near-edge structure (XANES) spectroscopies have been used to study the element and phase composition, and Fe and Ni oxidation states in ordinary chondrites. The meteorites have been initially classified as Markovka (H4 type), Polujamki (H4 type), Sayh al Uhaymir (SaU) 001 (L5 type), Dhofar (Dho) 020 (H4/5 type), and Jiddat al Harasis (JaH) 055 (L4-5 type). We have applied a set of spectroscopic methods to characterize and quantify the differences between samples. While the concentration of Fe in the meteorites is in agreement with the qualitative assignment of their types (L or H) made upon discovery, we observed extremely low Mg/Si and Al/Si values compared to the data published by Palme et al. (2014). Phase content of the meteorites has been studied by means of XRD, as well as by SEM and EDX. M€ ossbauer spectroscopy of Fe-containing phases has determined that Fe ions are present mainly in olivine and pyroxene phases in all studied samples. Goethite, hematite, and troilite phases were found in Markovka, Polujamki, and Sayh al Uhaymir 001, respectively. Markovka and Polujamki samples contained the largest concentration of Fe-Ni-Co metal grains. Fe and Ni K-XANES spectra were analyzed to estimate metal oxidation state in the chondrites and compared with the M€ ossbauer data. The multispectral data acquired in the present work are of importance for further understanding of meteoritic processes.
