“…In addition, there is no detailed description of the stilbite Raman spectrum although some general assignments are given for the bands below 500 cm −1 [136,137]. On the other hand, attention has been focused on the Raman spectral analysis of feldspars: albite [138][139][140][141][142][143][144][145], microcline [144,146] and sanidine [143,146]. However, the results from this work give clearer insight into the vibrational spectral characteristics of this geologically important min-eral group particularly at lower wavenumbers.…”

Micro-Raman Spectroscopy and X-ray Diffraction Analyses of the Core and Shell Compartments of an Iron-Rich Fulgurite

et al. 2022

Fulgurites are naturally occurring structures that are formed when lightning discharges reach the ground. In this investigation, the mineralogical compositions of core and shell compartments of a rare, iron-rich fulgurite from the Mongolian Gobi Desert were investigated by X-ray diffraction and micro-Raman spectroscopy. The interpretation of the Raman data was helped by chemometric analysis, using both multivariate curve resolution (MCR) and principal component analysis (PCA), which allowed for the fast identification of the minerals present in each region of the fulgurite. In the core of the fulgurite, quartz, microcline, albite, hematite, and barite were first identified based on the Raman spectroscopy and chemometrics analyses. In contrast, in the shell compartment of the fulgurite, the detected minerals were quartz, a mixture of the K-feldspars orthoclase and microcline, albite, hematite, and goethite. The Raman spectroscopy results were confirmed by X-ray diffraction analysis of powdered samples of the two fulgurite regions, and are consistent with infrared spectroscopy data, being also in agreement with the petrographic analysis of the fulgurite, including scanning electron microscopy with backscattering electrons (SEM-BSE) and scanning electron microscopy with energy dispersive X-ray (SEM-EDX) data. The observed differences in the mineralogical composition of the core and shell regions of the studied fulgurite can be explained by taking into account the effects of both the diffusion of the melted material to the periphery of the fulgurite following the lightning and the faster cooling at the external shell region, together with the differential properties of the various minerals. The heavier materials diffused slower, leading to the concentration in the core of the fulgurite of the iron and barium containing minerals, hematite, and barite. They first underwent subsequent partial transformation into goethite due to meteoric water within the shell of the fulgurite. The faster cooling of the shell region kinetically trapped orthoclase, while the slower cooling in the core area allowed for the extensive formation of microcline, a lower temperature polymorph of orthoclase, thus justifying the prevalence of microcline in the core and a mixture of the two polymorphs in the shell. The total amount of the K-feldspars decreases only slightly in the shell, while quartz and albite appeared in somewhat larger amounts in this compartment of the fulgurite. On the other hand, at the surface of the fulgurite, barite could not be stabilized due to sulfate lost (in the form of SO2 plus O2 gaseous products). The conjugation of the performed Raman spectroscopy experiments with the chemometrics analysis (PCA and, in particular, MCR analyses) was shown to allow for the fast identification of the minerals present in the two compartments (shell and core) of the sample. This way, the XRD experiments could be done while knowing in advance the minerals that were present in the samples, strongly facilitating the data analysis, which for compositionally complex samples, such as that studied in the present investigation, would have been very much challenging, if possible.

“…For example, the infrared spectral analyses from the Viking and Pathfinder missions indicate possible occurrences of salts on the Martian surface in soils, cements, rocks and dust in the atmosphere, which has significant proportions of Na and Cl (Lane & Christensen 1998 ;Gilmore et al 2004;Bishop et al 2004 ;King et al 2005). Other research on Martian brines proposes that there may be several sites on Mars where hypersaline waters may exist in the shallow crust, thus creating the potential near the surface for an environment for life (Pierson & Parenteau 2000;Ruff et al 2001;Bishop et al 2004;Edwards et al 2005a,b;Villar & Edwards 2005). Remote characterization and the location of these spots have important future applications regarding site selection of astrobiological missions to Mars (e.g.…”

Spectroscopic investigations of surface mineral components, expected to exist on the surface of Mars, using multiple spectral ranges and techniques, are vital to obtain the ground truth information or reference data for Mars exploration missions. This paper presents visible, near-infrared, thermal infrared reflectance and thermal infrared transmission spectra, as well as X-ray diffraction and scanning electron microscope/energy dispersive X-ray analyses of salt crusts and sediments interleaved with cyanobacterial materials from a coastal zone of the United Arab Emirates, where sabkhas exist. The samples obtained from sabkhas were characterized because they contain minerals requiring the water for formation and they provide a possible environment for some of the earliest organisms on Earth. The surface minerals identified include gypsum, calcite, halite, aragonite and dolomite. These sediments were found to be mixed with each other and intermingled with an algal mat, which consisted of cyanobacteria. If such materials formed in similar environments on Mars, their identification would be important for understanding the geobiological conditions of the planet and the potential habitability for life.
