Elpidite : Na2ZrSi6O15·3H2O

Demix-Varennes quarry, Saint-Amable sill, Varennes & St-Amable, Lajemmerais RCM, Montérégie, Québec, Canada

FOV 1.8 x 1.1 mm. Collected by Modris B. Oct 1998. Analyzed find.
The habit – pinacoidal termination - is very similar to elpidite from the Poudrette pegmatite and contact zone at MSH. The xls are well formed but they are in highly weathered cavities from the top of the sill. Hence full of crud which partially obscures the xls and makes them of ...

Collection of Modris Baum. FOV 1.1 x 1.0 mm. See next photo for a stereo view.
The apparently pinacoidal terminations may seem surprising. But this is typical of elpidite from the vicinity of the "Poudrette" pegmatite.
The elpidite ID has now been confirmed by Pavel Kartashov on another part of the specimen. This elpidite has an unusual and ...

Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

Here we have an outstanding example of the relatively rare hydrated Sodium Zirconium Silicate mineral Elpidite. This aesthetic specimen is comprised of three jack-straw-like bundles of Elpidite that have an attractive silky luster. Typically the larger Elpidite clusters from the pegmatites of Mont Saint-Hilaire are not terminated, however, this ...
