Summary edit

Description
English: Niveolanite, Aegirine, Rhodochrosite, Microcline (FOV ~ 4+ cm wide)
Locality: Poudrette quarry (De-Mix quarry; Demix quarry; Uni-Mix quarry; Carrière Mont Saint-Hilaire; MSH), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada
Thanks to Jean-Pierre Beckerich. MOB coll.
A fragment of this specimen was XRD confirmed (as UK113) at the Canadian Museum of Nature. The color is distinctly yellowish. Out of view there is a great deal of unaltered petersenite-(Ce) (see child photo), but only a couple of terminated xls. Also out of view are "beehives" of tan/gray catapleiite with a bit of franconite in the interstices. Other specimens have (verified) franconite directly associated with the niveolanite. But here, most of the fuzzy white stuff is "short hair" niveolanite or (in very small amounts) dawsonite. This specimen came from the Poudrette pegmatite. Various child photos including closeups and stereo views. Oct 2009: I think I finally achieved reasonable color fidelity!
