Ellinaite, CaCr<sub>2</sub>O<sub>4</sub>, a new natural post-spinel oxide from Hatrurim Basin, Israel, and Juína kimberlite field, Brazil

“…Observed Raman bands are (cm −1 ) ∼ 1300 (combination first-order phonons A g in the 680-700 range); 689, 598 and 556 (A g -stretching modes); 470 and 441 (B 2g and A g -tilting and bending modes); 387, 337 and 324 (A g , B 1g and B 3g -rotating modes); 243 and 204 (A g ); 140 (A g and B 2g ); and 123 and 107 (A g ) (Ca-related vibrations). In general, Raman spectra of ellinaite from Hatrurim Basin are similar to those of ellinaite from Jordan (Galuskina et al, 2021a).…”

“…The mineral was approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA) as a new mineral species in December 2019, IMA 2019-091 (Sharygin et al, 2020). After the IMA registration, the same mineral has also been identified in varicolored spurrite marbles at Tulul Al Hammam, Daba-Siwaqa, Hatrurim pyrometamorphic formation, central Jordan (Galuskina et al, 2021a).…”

“…5) strongly suggest the occurrence of limited isomorphous substitutions according to possible schemes: Cr 3+ ↔ (V 3+ ,Ti 3+ ) and S3 and S4. Composition of ellinaite in the Brazilian diamond (Kaminsky et al, 2015) (Galuskina et al, 2021a). The Hatrurim ellinaite has higher concentrations of Ti (dominantly Ti 3+ ) and V and a lower amount of Fe (dominantly Fe 2+ ) compared with the other two occurrences.…”

Crocobelonite, CaFe23+(PO4)2O, a new oxyphosphate mineral, the product of pyrolytic oxidation of natural phosphides

“…Calcium, the classic lithophile element, forms sulfides -oldhamite CaS and dzierżanowskite, CaCu2S2 (Galuskina et al 2017). Other mineralogical highlights include oxides, such as grossite, CaAl4O7, discovered simultaneously in the Hatrurim Formation and within calcium-aluminium inclusions (CAI) of carbonaceous chondrites (Weber and Bischoff 1994); perovskite-supergroup minerals: vapnikite -the double perovskite CaCaUO6 (Galuskin et al 2014), shulamitite Ca3TiFe 3+ AlO8 (Sharygin et al 2013), cubic oxygen-deficient perovskite Ca(Ti,Si,Cr)O3-δ (Britvin et al 2022c), and aluminate garnet priscillagrewite-(Y), (Ca2Y)Zr2(AlO4)3 (Galuskina et al 2021b).…”

Deynekoite, Ca9□Fe3+(PO4)7 – a new mineral of the merrillite group from phosphide-bearing contact facies of paralava, Hatrurim Complex, Daba-Siwaqa, Jordan

“…We also consider the mechanism and conditions of deynekoite formation in phosphide-bearing contact facies of paralava from Jordan. The mineral and its name (symbol Dnk) have been approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA), as IMA 2020-108 (Galuskin et al, 2022b). The name deynekoite is given in honour of Dr Dina V. Deyneko (born 1988) for her valuable contribution to the investigation of synthetic analogues of merrillite-group minerals (Deyneko et al, 2014).…”
