Kishonite, VH2, and Oreillyite, Cr2N, two new minerals from the corundum xenocrysts of Mt Carmel, Northern Israel
Abstract
Here, we describe two new minerals, kishonite (VH<sub>2</sub>) and oreillyite (Cr<sub>2</sub>N),found in xenoliths occurring in pyroclastic ejecta of small Cretaceousbasaltic volcanoes exposed on Mount Carmel, Northern Israel. Kishonitewas studied by single-crystal X-ray diffraction and was found to becubic, space group Fm3¯m, with a = 4.2680(10) Å, V = 77.75(3) Å<sup>3</sup>,and Z = 4. Oreillyite was studied by both single-crystal X-raydiffraction and transmission electron microscopy and was found to betrigonal, space group P3¯1m, with a = 4.7853(5) Å, c = 4.4630(6) Å, V = 88.51 Å<sup>3</sup>,and Z = 3. The presence of such a mineralization in these xenolithssupports the idea of the presence of reduced fluids in thesublithospheric mantle influencing the transport of volatile species(e.g., C, H) from the deep Earth to the surface. The minerals and theirnames have been approved by the Commission of New Minerals, Nomenclatureand Classification of the International Mineralogical Association (No.2020-023 and 2020-030a).
