“…This could mean that the sulfate was locally sampled and only represented a thin surface coating on a fragment of impact glass, and thus was reasonably a product of Antarctic weathering and not of indigenous lunar volatiles. On the other hand, it has been shown that Raman analysis can degrade or decompose sulfate minerals (Rosasco and Roedder 1979;Fries and Steele 2010) and thus, the original sulfate grain or coating could have been destroyed during the preliminary examination. Bulk composition data from: PCA 02007, Korotev et al (2006); ALHA81005, Palme et al (1983); Dhofar 026, Warren et al (2005).…”

A grain of light‐blue sulfate material was reported in the lunar highlands regolith meteorite PCA 02007 (Satterwhite and Righter 2013). Allocated grains of that material are, in fact, aluminosilicate glass with a chemical composition like that of the bulk meteorite and other lunar highlands regoliths. The calcium sulfate detected in PCA 02007 was likely a surface coating, and reasonably of Antarctic (not lunar) origin.

“…To minimize any possible anisotropy effect on the intensity resulting from random crystallographic orientation of analyzed grains [28] and to avoid sample thickness effect, the analysis of each specimen was repeated 4 times on various grains. Interpretation of spectra was performed with the aid of OMNIC for Dispersive Raman software.…”

A total of seven compounds of the hydroxylpyromorphite Pb10(PO4)6(OH)2 - hydroxylmimetite Pb10(AsO4)6(OH)2 (HPY-HMI) solid solution series were synthesized at 80°C from aqueous solutions and characterized using Raman spectroscopy. The positions of the bands in all spectra of the series depend on the content of arsenates and phosphates shifting to lower wavenumbers with substitution of (AsO4)(3-) for (PO4)(3-). This shift results from the decreasing bond strength of X-O (where X=P, As) and higher atomic mass of As than P. The position and intensity of major (PO4)(3-) and (AsO4)(3-) bands in Raman spectra exhibit linear correlation with As content, while the ratio of the intensities of these peaks shows exponential correlation. This results due to different polarizability of (PO4)(3-) and (AsO4)(3-) molecules. A small carbonate band develops with increasing As content indicating that hydroxyl lead apatites adopt the (CO3)(2-) ions, particularly at the arsenate end of the series.

“…We show that the contaminant infrared feature at 1261 cm À1 is absent in all spectra of the studied samples. Thin section preparation may also contaminate the samples with artificial organic matter (Fries and Steele 2010), which result in stronger aliphatic CH bands near 3000-2800 cm À1 in the infrared spectra. However, the infrared spectra presented here do not have such strong aliphatic CH bands, and therefore organic contamination in our samples is less likely.…”

“…Thin section preparation has been reported to potentially modify/disrupt carbonaceous phases, which may lead to modified Raman D and G carbon peak parameters (Pasteris 1989;Fries and Steele 2010). In an effort to eliminate this problem, we collected the Raman imaging data at 2.5 lm depth below the surface in all samples.…”

As of today, the Sariçiçek (SC) meteorite is the newest howardite and the only confirmed fall among the 17 known howardites. In this study, we present isotopic, infrared, and Raman data on three distinct pieces of the SC meteorite. Our oxygen isotopic measurements show that Δ17O values of the pieces are close to each other, and are in good agreement with other howardites, eucrites, and diogenites. The carbon isotopic measurements, which were conducted by combusting terrestrial contamination selectively at temperatures lower than 500–600 °C, show the presence of indigenous carbon in the SC specimens. The matrix of these specimens, investigated via infrared microspectroscopy, appears to be dominated by clinopyroxene/orthopyroxene, forsterite, and fayalite, with minor contributions from ilmenite, plagioclase, and enstatite. Carbon‐rich regions were mapped and studied via Raman imaging microspectroscopy, which reveals that both amorphous and graphitic carbon exist in these samples. Synchrotron‐based infrared microspectroscopy data show the presence of very little aliphatic and aromatic hydrocarbons. The SC meteorite is suggested to be originating from the Antonia impact crater in the Rheasilvia impact basin on 4 Vesta (Unsalan et al. 2019). If this is in fact the case, then the carbon phases present in the SC samples might provide clues regarding the impactor material (e.g., carbonaceous chondrites).
