The Rock Cycle Illustrated
Although not specifically fluorescent mineral oriented, these graphics are a great illustration of how our rocks are created. Just add some activators into the cycle and we have fluorescent rocks!Processes that shape the earth's surface are ongoing, continuously or...
What’s the Difference Between Fluorescence and Bioluminescence?
What’s the difference between fluorescence and bioluminescence? We illuminate the biochemical distinctions.
The science of fluorescent minerals by Bob Oblack
A presentation on COLOR & ENERGY... Learn the scientific concepts behind why rocks glow in the dark. This video provides an in-depth look into the science behind fluorescent minerals, presented by Bob Oblack. It covers the science of color and energy, luminescence and...
What is Thermoluminescence?
Thermoluminescence is phosphorescence triggered by temperatures above a certain threshold. This should not be confused with incandescence, which occurs at higher temperatures. In thermoluminescence, heat is not the primary source of the energy, only the trigger for...
Fluorescence Spectroscopy and Zoning of Apatite
At the Rochester Mineralogical Symposium in 2022 Madeline Murchland gave a very nice presentation about fluorescence spectroscopy and zoning in apatite. Here is a recording of her talk.
Life Saver Triboluminescence
Some comments from our Facebook Group: JB: Worth noting: if you want to try this at home, they have to be Wint-o-green lifesavers, not pep-o-mint. The oil of wintergreen (methyl salicylate) is fluorescent, and the sugar breaking produces UV light, causing the methyl...
