Description:
Tugtupite fluoresces a cherry red under SW and encircles a whitish/magenta fluorescing chkalovite. Bluish fluorescence is analcime, and the orange is sodalite. Most areas of green fluorescence are uranyl activated. Sodalite areas are nicely tenebrescent.
This combination species has been given the nickname "Fantasy Rock" for the wildly fluorescent and colorful varieties found on the Taseq Slope, Ilimaussaq Complex, Greenland. Full set of pictures in the gallery below....
