Sodalite (Hackmanite), Tugtupite, Chkalovite, Analcime(?) - Ilimaussaq Complex, Greenland
This material is striking. The sodalite appears as crystal blebs in matrix, with a few spots of tugtupite encircling a bright white chkalovite. Areas where the sodalite contacts the matrix are fluorescent a bright bluish/white (perhaps with a green tint). Conventional wisdom has been that this is analcime, but I am having my doubts. The fluorescent analcime from this area is a bright blue/white and usually solid (massive) crystals. This is different. The fluorescence also occurs in the black area (which is non-fluorescent lujavrite). Also, beautiful little sprays of dark green aegirine crystals cover both faces. Another Greenland beauty (and mystery).
