Perovskite is a calcium titanium oxide mineral species composed of calcium titanate, with the chemical formula CaTiO3.
The mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792–1856).[1]
It lends its name to the class of compounds which have the same type of crystal structure as CaTiO3 (XIIA2+VIIB4+X2–3) known as the perovskite structure.[9] The perovskite crystal structure was published in 1945 from X-ray diffraction data on barium titanate by the Irish crystallographer Helen Dick Megaw (1907–2002).
Basically found in the earth’s mantle, the perovskite’s occurrence at Khibina Massif is restricted to the under saturated ultramafic rocks and foidolites, due to the instability in a paragenesis with feldspar. The complexity is made by an extended series of rocks from early alkaline ultramafic members to late carbonatites that comprise alkaline and mafic igneous rocks such as nepheline syenite, melilitite, kimberlite and rare carbonatites in ultramafites. Perovskite occurs as small anhedral to subhedral crystals filling interstices between the rock-forming silicates
