Fluorite - Wikipedia

George Gabriel Stokes named the phenomenon of fluorescence from fluorite, in 1852. Many samples of fluorite exhibit fluorescence under ultraviolet light, a property that takes its name from fluorite. Many minerals, as well as other substances, fluoresce. Fluorescence involves the elevation of electron energy levels by quanta of ultraviolet light, followed by the progressive falling back of the electrons into their previous energy state, releasing quanta of visible light in the process. In fluorite, the

Discover Evaporite Minerals and Halides - ThoughtCo

Jan 16, 2020  Fluorite (be careful not to spell it "flourite") forms at shallow depths and relatively cool conditions. There, deep fluorine-bearing fluids, like the last juices of plutonic intrusions or the strong brines that deposit ores, invade sedimentary rocks with lots of calcium like limestone. Thus, fluorite is not an evaporite mineral.
