Perovskite is an accessory mineral in silica-poor rocks, such as nepheline syenite, kimberlite (common) and carbonatite. It also occurs in calcareous skarn. It is common in chlorite, talc or serpentine rocks (Webmin, HOM). Associated minerals include åkermanitegehlenite, nepheline, titanite, ilmenite and magnetite (HOM).

Localities

The type locality is the Akhmatovskaya Kop', Nazyamskie Mountains, Zlatoust, Chelyabinsk Oblast, Russia.
