Summary edit

Description
English: Dawsonite
Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada
Original description: Dawsonite xls to ~ 1 cm of which ~ 6mm is visible in the photo. Via Jean-Pierre Beckerich. MOB coll.
This is one of the four common habits for dawsonite at Mont Saint-Hilaire: blocky (File:Dawsonite-304893.jpg), water clear striated long prismatic (this specimen), fibrous (File:Dawsonite-169628.jpg) and as a powdery "mud" sometimes filling entire cavities (File:Dawsonite-267906.jpg). The orange/yellow stuff is probably very thin – almost micaceous - gmelinite. (Thanks to Peter T. for this information.)
Deutsch: Dawsonit
Fundort: Steinbruch Poudrette (Demix, Uni-Mix, Desourdy), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Kanada
Beschreibung: Dawsonit-Kristalle sind ≈ 1 cm, von denen etwa 6 mm im Bild sichtbar sind.
Dies ist eine von vier allgemeinen Erscheinungsformen von Dawsonit am Mont Saint-Hilaire: Blockig (File:Dawsonite-304893.jpg), wasserklar und langprismatisch gestreift (diese Probe), faserig (File:Dawsonite-169628.jpg) und gelegentlich als pudrige Krusten und Hohlraumfüllungen (File:Dawsonite-267906.jpg).
Das gelborange Material ist vermutlich sehr dünner - nahezu glimmerähnlicher - Gmelinit.
