Kishonite, VH<sub>2</sub>, and Oreillyite, Cr<sub>2</sub>N, Two New Minerals from the Corundum Xenocrysts of Mt Carmel, Northern Israel

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 Cretaceous basaltic volcanoes exposed on Mount Carmel, Northern Israel. Kishonite was studied by single-crystal X-ray d...
