Polylithionite Rose from Mt. St. Hilaire

  (English version)

Polylithionite rose over a small microcline matrix. Fluorescence is the tipical yellow in Sw and in this sample it’s quite pale. The photos are with 60W lamp. On the “rose petals” are several cubic micro-cristals of an unidentified mineral that fluoresces pale blue.

It comes from Poudrette Quarry, Mont St-Hilaire, Quebec, Canada.

Rosetta di Polylithionite sopra una matrice di microcline. La fluorescenza (in onda corta) è gialla e piuttosto debole. Le foto sono state realizzate con una lampada da 60W. Sulla Polylithionite sono presenti anche numerosi cristalli cubici sub-millimetrici debolmente fluorescenti azzurro di un minerale non identificato.

Provenienza: Mont St-Hilaire, Quebec, Canada.

                                                                                            

 SW. In this photo 2 by 30W lamps were used.  Some (but not all)  blue on the "petals edge" are reflections. Sorry but I cannot avoid them.

Pale blue dots into the rose middle are true fluorescence of an unkown mineral.... see macro below (last picture).

(Per realizzare questa foto sono state usate due lampade in onda corta da 30W). Alcune sfumature (ma non tutte) di colore azzurro al bordo dei petali sono riflessioni che non sono riuscito ad evitare. I punti azzurri al centro della rosa invece sono reali fluorescenze di un minerale sconosciuto. Vedi i dettagli nell'ultima foto).

 

 The same shot of the previously photo but in Natural light.
