Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada FOV 2.6 x 3.1 mm. Collected by Modris B. July 1994. Another gaidonnayite from my "reject" bucket. See http://www.mindat.org/photo-171392.html The color is "blah" gray - but it shows the morphology clearly even without stereo.

Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O, Calcite : CaCO₃, Siderite : FeCO₃, Microcline : K[AlSi₃O₈]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada This pegmatite oddity features a vug lined with Gaidonnayite, the rare dimorph of the mineral Catapleiite. Also present in the vug are several flower-like sprays of Calcite. This specimen also features many crystals of Siderite embedded in the Microcline matrix. specimen size = 7 x 4.2 x 3 cm.

Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Self collected by Modris Baum July 1994. FOV 3.1 x 2.4 mm. This is from the upper part of the Poudrette pegmatite. The lighting has been arranged to emphasize the iridescence common for specimens from this find. This is a fairly complex but typical twin from the find.

Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Self collected by Modris Baum July 1994. FOV 2.5 x 2.2 mm. This is a relatively simple twin. The iridescence is typical for gaidonnayite from the upper part of the Poudrette pegmatite. The xls from this find fluoresce very strongly (green).

Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O, Microcline : K[AlSi₃O₈], Albite : Na[AlSi₃O₈]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Width of photo ~ 3 cm. The largest cluster of gaidonnayite (lhs) is ~ 3.5 mm. This gaidonnayite is highly fluorescent (green). The xls on this specimen even look greenish in daylight. This is from Jean-Pierre Beckerich but I collected nearly a bucket of such xls on my 3rd trip to MSH (July 1994). It was all stuff rejected by the folks who ...

Gaidonnayite : Na₂Zr[Si₃O₉]·2H₂O
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Self collected by Modris Baum May 1997. FOV 1.8 x 1.4 mm. This is an unusually simple xl. It is also unusual in that it fluoresces only weakly. It came from a breciated hornfels rather than a pegmatite. See next photo for a stereo view.
