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, and analcime and they are always the most color-rich pieces from this exotic, remote locale.
The sodalite in these rocks is almost always very tenebrescent, as seen in the animation below
