Plutonic igneous environments
At the type Locality, the Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Quebec, Canada, a massive hornfels unit, its contact zone, and accompanying inclusions and xenoliths were exposed during quarry operations. Griceite was found in sodalite inclusions at the periphery of the contact zone of the hornfels, which is surrounded by nepheline syenite. On a type specimen griceite occurs as late-stage botryoidal aggregates to 1 mm on ussingite crystals associated with sodalite, eudialyte, sphalerite, serandite, vuonnemite and lovozerite (CM 27.125-127, HOM). Griceite also occurs as inclusions in vuonnemite or pseudomorphs of it (Dana).
