Saint-Amable sill, Varennes & St-Amable, Lajemmerais RCM, Montérégie, Québec, Canada FOV ~ 3 cm wide. Found June 1996.

Demix-Varennes quarry, Saint-Amable sill, Varennes & St-Amable, Lajemmerais RCM, Montérégie, Québec, Canada FOV ~ 3 cm wide. Found June 1996. Yofortierite is relatively common at STA.

Raite has not been found. Hence specimens such as this one are almost certainly ... |

Demix-Varennes quarry, Saint-Amable sill, Varennes & St-Amable, Lajemmerais RCM, Montérégie, Québec, Canada FOV 1.1 x ¾ cm. Collected by Modris B. June 1996.
