Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Description
Comments:Probably the best analcime specimens I have ever seen have been from St Hilaire. Some crystals are about 15 cm in diameter and often associated with other interesting minerals like aegirine and serandite. Specimens that have interesting associations are always more appreciated by collectors. Pseudomorphs of cancrinite or burbankite(?) to 25cm. Formed in zoned pockets up to 1.3 by 2.6 meters.
Habit:Trapezohedra up to 25cm across
Colour:Transparent colorless to opaque white or gray in larger crystals
Quality of samples:Excellent - world class for species or very significant. (!!)
Rarity at site:Common
Confirmation
Validity:Believed Valid
