“…Summing up, the isocon method does not reveal any suitable correlations between components of CM rocks and the protolith proposed by Geller et al (2012). Moreover, concentrations of at least half of the components may be achieved by assuming ridiculous losses (more than 45 wt%) which is impossible for a carbonate-rich protolith.…”

“…We used the chemical and geochemical data for the lower chalk member of the Ghareb Formation according to Geller et al (2012), and for other chalks of the Ghareb and Taqiye Formations, according to Bogoch et al (1999). To test this hypothesis, we compared compositions of larnite-bearing and gehlenite-rich rocks to the lower chalk member of the Ghareb Formation, to other chalk of the Ghareb Formation, and to chalky-marly rocks of the Paleocene Taqiye Formation.…”

“…Nahal Darga belongs to the Hatrurim Complex - a geological formation extending into the Israel, Palestine, and Jordan. There are two main hypotheses explained formation of pyrometamorphic rocks of the Hatrurim Complex related to high-temperature alteration of sedimentary protolith as a result of natural burning processes (1) of dispersed organic matter contained in primary sedimentary rocks 23–25 and (2) high-temperature pyrometamorphism of primary rocks driven by methane combustion exhaling from tectonic active zones of the Dead Sea rift 22,26 . Larnite pseudoconglomerates are one of the most interesting rocks of the Hatrurim Complex.…”

The mayenite group includes minerals with common formula Ca12Al14O32−x(OH)3x[W6−3x], where W = F, Cl, OH, H2O and x = 0–2. This distinction in the composition is associated with W site which may remain unoccupied or be occupied by negatively charged ions: OH−, F−, Cl−, as well as neutral molecules like H2O. However, there is no experimental approach to easily detect or differentiate mineral species within the mayenite group. Electron micro-beam facilities with energy- or wavelength-dispersive X-ray detectors, as most common tools in mineralogy, appear to be insufficient and do not provide a definite identification, especially, of hydroxylated or hydrated phases. Some solution provides typical Raman analysis ensuring identification of minerals and 3D Raman imaging as an innovative approach to distinguish various co-existing minerals of the mayenite group within a small area of the rock sample. Raman spectroscopy has also been successfully used for a determination of water type incorporated into the mineral structure as well as for a spatial distribution of phases by cluster approach analysis and/or integrated intensity analysis of bands in the hydroxyl region. In this study, Raman technique was for the first time used to reconstruct a 3D model of mayenite group mineral zonation, as well as to determine a way of water incorporation in the structure of these minerals. Moreover, for the first time, Raman data were correlated with alterations during the mineral-forming processes and used for reconstruction of the thermal history of studied rock. As a result, the influence of combustion gases has been proposed as a crucial factor responsible for the transformation between fluormayenite and fluorkyuygenite.
