Plutonic igneous environments
Cancrinite is a primary mineral in some
alkaline igneous rocks, including
in nepheline syenite. It is also an alteration product of
nepheline in igneous rocks
At Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Quebec, Canada, cancrinite pseudomorphs after natrolite have been found with rhodochrosite (KL p265).
Common impurities: Ti,Fe,Mg,K,Cl,S
