Adamsite-(Y) : NaY[CO3]2 · 6H2O, Aegirine : NaFe3+[Si2O6], Microcline : K[AlSi3O8]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Modris Baum collection. FOV approx 3.0 x 2.1 cm. The adamsite-(Y) sits on a "boulder" approx 18 x 10 x 7 cm that I'm afraid to trim for fear of losing the adamsite-(Y). It flies of if you sneeze! As it is, much of the adamsite-(Y) is behind the most inconveniently placed microcline fragment in the foreground. Other parts of this "boulder" have ...

Aegirine : NaFe3+[Si2O6], Calcite : CaCO3
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Self collected by Modris Baum July 1995. FOV 2.5 x 2.7 mm. One expects aegirine to be "pointy". But these (analyzed) xls are bladed. (Strictly speaking they are "clinopyroxene" since detailed chemistry was not done.) The small clear xl near the top is calcite. This is a single focus film shot. The two child photos, both stereo, show the bladed ...

Aegirine : NaFe3+[Si2O6], Natrolite : Na2[Al2Si3O10] · 2H2O
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Modris Baum collection. The aegirine xl is about 1.9 cm tall. It sits on gray natrolite prisms. The xls is a twin - the twinning plane ("B") is clearly visible from the top (see child photo). The visible portions is one of the twins. the other child photo is a stereo view.

Aegirine : NaFe3+[Si2O6]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Self collected by Modris Baum August 1999. FOV 1.6 x 1.1 cm. Here are some nice "pointy" aegirine xls from a miarolitic cavity. The xls are actually dark gray but are largely covered by a somewhat shiny black amorphous coating. This can be seen more clearly in the child photo. The gray xl with a flat top (rhs) is either sphalerite or ...

Aegirine : NaFe3+[Si2O6]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Modris Baum collection (ex Ron Waddell). FOV 4.6 x 6.8 mm. This is a nice "pointy" xl with no coating. It came from a miarolitic cavity with cm sized burbankite. Unfortunately it decided to "leap off" this specimen during a photo session. The child photo is a stereo view.

Aegirine : NaFe3+[Si2O6]
	Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada Self collected by Modris Baum July 1999. FOV 1.4 x 2.0 mm. These small secondary xls have the same color as some astrophyllite and could easily be taken for that mineral at first glance.
