Loveringite: Properties and Occurrences

Loveringite is a rare metallic oxide mineral of the crichtonite group with the chemical formula (Ca, Ce) (Ti, Fe, Cr, Mg)21O38. It is a trigonal-rhombohedral black mineral containing aluminum, calcium, cerium, chromium, iron, magnesium, oxygen, titanium, vanadium, and zirconium. It is a late-stage magmatic mineral, formed in the residual melt of mafic layered intrusions in the olivine-chromite, pyroxene, or plagioclase-rich layers. It is a naturally occurring compound, a mineral is usually found in the crystalline form.
