Brightly Fluorescent Tugtupite from the Taseq Slope, Ilimaussaq complex, Kujalleq, Greenland

This brightly fluorescent tugtupite specimen was collected in 2005 by Mark Cole from the Western Taseq Slope of the Ilmaussaq complex, Kujalleq, Greenland. In addition to the pink tugtupite, this rock also features white albite, yellow grains of polylithionite, grey analcime, chkalovite and dark grains of non-fluorescent arfvedsonite. The size of this specimen is 99 x 88 x 83 mm and it weighs 796 grams.

Shown in the above photograph under short wave UV (254 nm), the tugupite fluoresces bright cherry red, albite shows a dim magenta response, polylithionite fluoresces yellow and analcime shows a pale blue response.

Following exposure to short wave UV (254 nm), the tugtupite shows pale pink to white phosphorescence/afterglow.

Under long wave UV (365 nm), the tugtupite fluoresces bright orange and the analcime shows a pale blue/white response.
