First evidence of natural elemental fluorine

First direct evidence that elemental fluorine occurs in nature – Fluorine is the most reactive chemical element. Until now, the accepted scientific doctrine was that therefore it cannot exist in nature in its elemental form. A team of chemists from Munich has now, for the first time, successfully identified natural elemental fluorine in a special fluorite, the "fetid fluorite" or "antozonite."
