Laverovite is a relatively new mineral, approved in 2018 and to date (July 2022) reported only from the type locality

Localities

At the type locality, the Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Quebec, Canada, laverovite occurs in a nepheline syenite pegmatite. Associated minerals are zircophyllite, kupletskite, astrophyllite, aegirine, analcime, orthoclase and albite. The laverovite formed as a late-stage hydrothermal mineral (CM 57.201-213)
