Summary[edit]

Description
English: Polylithionite, Catapleiite
Field of view: ~ 1.5 X 1.3 cm
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
Description: Found May 1996. The transparent hex plates on the tan are polylithionite. The tan needles are may be secondary aegirine, but they looks as if they are coated by rhabdophane-(Ce). The black stuff is primary aegirine. There is also genthelvite and (recognizeable) rhabdophane-(Ce), but they are not in the photo. The catapleiite is the tan rosettes on the bottom - ut it looks altered. (Somewhat similar material from another pegmatite was found to be replaced by rhabdophane-(Ce) or monazite-(Ce) via "quick & dirty" EDS, which cannot distinguish these two species. But this material t has not been analyzed.)
Deutsch: Polylithionit, Katapleiit
Sichtfeld: ~ 1,5 X 1,3 cm
Fundort: Steinbruch Poudrette, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Kanada
Beschreibung: Gefunden im Mai 1996. Die transparenten Sechskantplatten auf der Bräune sind Polylithionit. Die hellbraunen Nadeln sind möglicherweise sekundäres Aegirin, aber sie sehen aus, als ob sie von Rhabdophan-(Ce) überzogen wären. Das schwarze Zeug ist primäres Aegirin. Es gibt auch Genthelvin und (erkennbar) Rhabdophan-(Ce), aber sie sind nicht auf dem Foto. Der Katapleit sind die braunen Rosetten auf der Unterseite - aber es sieht verändert aus. (Etwas ähnliches Material von einem anderen Pegmatit wurde mittels „quick & dirty“ EDS durch Rhabdophan-(Ce) oder Monazit-(Ce) ersetzt, wodurch diese beiden Arten nicht unterschieden werden können. Dieses Material wurde jedoch nicht analysiert.)
