This greenish sodalite (hackmanite) is very tenebrescent. Uranyl activated greens and chkalovite make for an interesting pattern. There is some minor tugtupite as well.

Greenland produces some of the most tenebrescent sodalite found anywhere. These pieces darken when exposed to SW UV in seconds, and fade just as rapidly upon exposure to a bright white light. This process can be repeated over and over. They are also perhaps the most fluorescent of the sodalites found around the world - a bright yel/orange under LW and SW, but under SW as the tenebrescence sets it, the color darkens to a rusty orange. Photos show SW and LW, as well as the tenebrescence. The animation shows this color change before/after UVC.

Long Lake Zinc Mine - Ontario Canada

The sun was slowly setting so we made dinner and relaxed a while (amazing how slowly the sun sets when you're waiting for it). Once it got dark collected started in earnest. The first thing you notice is the bright blue hydrozincite everywhere on red calcite. All of the small rocks glow. We proceeded to check out the large boulders laying around on the surface and quickly determined that dozens of prior collectors had done the same. That's why they're still lying around.
