A large specimen of this rare mineral, and one of the few specimens we found when we were on the Taseq slopes in july 2008. The Epididymite crystals (to 2,5cm large!) are, as usual, intergrown in the matrix and form twinned aggregates of thick white crystals. The Epididymite has some small embedded brown translucent Pyrochlore crystals. For more info, see Mindat (under MW and LW-UV a corner of the specimen fluoresces orange), and see our Greenland pictures and video's.

This is a rare piece of white fluorescent Polylithionite on Albite. Technically it's not from the Type Locality, although it's from the same geological complex, within viewing distance... We picked this up on the slopes of Mt.Ilimaussaq, which overlooks the Ilimaussaq-complex (it physically overlooks the Taseq slope, Kvanefjeld etc). The Polylithionite has a beautiful white-yellowish fluorescence under SW-UV (my lamp needs a Hoya filter...). For completeness we also added the MW-, LW-UV and some daylight images (pics from SW -> MW -> LW -> DL). For more info, see Mindat.
We promised you strange minerals from strange places, and that's what you'll get :)
