Pegmatite from alkaline intrusion (Hibiny, Kola Peninsula)

[diant]

Strong orange luminescence I found in one stone out of my collection.

This is a pegmatite from alkaline intrusion of Hibinsky massive. We pick up it with my wife many years ago.

My friend (geologist) counted in it up to 6 minerals, and one of them possess such bright orange luminescence. It may be orthoclase or nepheline.

 

 

Imaged by smartphone in a light of Convoy S2+ (Nichia 276C) with 2mm ZWB2.

It has a strong glow.

And as little happy boon - the small stone (pebbles) that I use for blocking my balcony window (when I look in telescope) proved to be with white phosphorescent mineral (also imaged by smartphone).

One second after Convoy S2+ was off. Gentle greenish phosphorescence. Very hard to image by telephone from hand :) Its phosphorescence is lasting 1-2 secs only.

And this - luminescence of Karelsky sapphires in the same 365nm light (Convoy S2+).

 

 

Wonderful ruby color...

Minerals are always a fascinating source of luminescence. I really like that last one.

 

Maybe you can make a cell phone video of the phosphorescence?

Andrea, I'll try, but not sure that the phone can so quickly rebuild its exposure, for the phosphorescence is very impetuous, one second and fade away. But the scene will have such differ lighting during Convoy ON and OFF status.
