A large fantasy rock with excellent chkalovite eyes. The main minerals on this specimen are tugtupite (cherry red SW), along with chkalovite (the rarer pearly white variety – a classic example of how tugtupite replaces chkalovite), blue analcime, sodalite (orange) and black arfvedsonite throughout the matrix. Under LW both the tugtupite and the sodalite fluoresce a bright orange (more salmon for the tugtupite).
The nickname "Fantasy Rock" encompasses a group of rocks found on the Taseq Slope in the Ilimaussaq Complex, Greenland and only in this one locality within the complex. A typical Fantasy Rock usually consists of four basic minerals: tugtupite, sodalite, chkalovite, analcime, and they are always the most color-rich pieces from this exotic, remote locale.
"Red" Sodalite (Hackmanite) - Deeply Tenebrescent Greenland Mineral
Red sodalite is named for the color it takes on when exposed to sunlight; it is nicely tenebrescent under longwave UV. Under shortwave UV the color deepens, in seconds, to almost black in some areas.
