We've made contact with a miner in the Afghan areas and have a supply of mine fresh material. The fluorescent activators have not been studied very much from this area. It's very unclear what is going on with most of the material from this locality, but as we get more material and discover new fluorescent minerals we will have them analyzed for proper IDs. But they sure do make for some confusing but amazingly beautiful fluorescent specimens. This piece (as most from Afghanistan) is best displayed using multiple wavelengths, although it is very respectable under SW alone (second pic) - or even MW or LW alone.

There are many scapolite (var. marialite) crystals that are fluorescent a bright yellow LW and dimmer yellow SW.

The matrix appears to have a bright white fluorescing mineral that is suggested to perhaps be diopside. Under SW the calcite fluoresces a dark orange, and the diopside crystals fluoresce a bluish white. Under MW (only) there are areas of a strong blue fluorescence from an unknown mineral - this is one of the few examples of MW only fluorescence we have observed (several closeups of this area are shown at the bottom). Phlogopite is bright yellow under SW, shifting to a bright butterscotch color MW and even deeper LW (very few phlogopites have this multi-wave response). Midwave causes the calcite to pop very nicely. Longwave brings out the yellow color of the afghanite crystals. MW and LW bring out the bright yellow of the marialite very nicely. If we were to display it under only one light, we would probably pick SW, preferably with a MW “kicker”.

Kangerlussaq Minerals - The Fluorescent Minerals of Greenland – Part 5

The Kangerluarsuk Fjord forms the southeast boundary of the Ilimaussaq Complex.  Like Tunulliarfik, the fjord cuts right through the complex.  Steep cliffs rise from each side of the fjord.  A large, relatively flat, rock-strewn area is located at the end of the fjord and is one of the three most productive areas in the complex.
