Summary

[edit]
Description
English: Polylithionite, Microcline, Albite
Field of view: 7.1 x 4.7 mm
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 August 1996. This is a comparison of SW UV fluorescence and visible light images. The UV image was made using a small SW UV LED “flashlight”. The response of the polylithionite in this case is almost pure bright yellow. There is no hint of the greenish tinge often seen for polylthionite. Hand-held, with the UV source about 5 cm from the specimen, the “glow” is easily visible from across a room, even in partial daylight. But the polylithionite from this find occurs as small isolated groups, so these are not “display” specimens. The magenta glow in the background is microcline. The paler, more pinkish, stuff in the foreground is albite. The specimen also has catapleiite and “pyrochlore”, but they are not visiblet in these photos.
Deutsch: Polylithionit, Mikroklin, Albit
Sichtfeld: 7,1 x 4,7 mm
Fundort: Steinbruch Poudrette, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Kanada
Beschreibung: Gefunden im August 1996. Dies ist ein Vergleich von kurzwelligem UV-Fluoreszenz- und sichtbaren Lichtbildern. Das UV-Bild wurde mit einer kleinen SW-UV-LED-„Taschenlampe“ erstellt. Die Reaktion des Polylithionits ist in diesem Fall fast rein hellgelb. Es gibt keinen Hinweis auf den grünlichen Farbton, der oft bei Polylithionit zu sehen ist. In der Hand gehalten, wobei die UV-Quelle etwa 5 cm von der Probe entfernt ist, ist das „Glühen“ selbst bei teilweisem Tageslicht von der anderen Seite des Raums aus gut sichtbar. Aber der Polylithionit aus diesem Fund kommt als kleine isolierte Gruppen vor, es handelt sich also nicht um „Ausstellungsstücke“. Das magentafarbene Leuchten im Hintergrund ist Mikroklin. Das hellere, rosafarbenere Zeug im Vordergrund ist Albit. Das Exemplar hat auch Katapleit und „Pyrochlor“, aber sie sind auf diesen Fotos nicht sichtbar.
