Mineralpedia Details for Liebigite
Liebigite
Named in honor of Justus von Liebig, a professor and German chemist at the University of Munich in Germany, who is credited as the founder of analytical chemistry. Liebigite is an uncommon mineral that occurs as an alteration product of uraninite in alkaline carbonatite solutions. It can be found in localities in Turkey, the Czech Republic, Germany, Poland, England, Scotland, France, the USA, Canada, Japan, and the Democratic Republic of the Congo, among others. Liebigite is radioactive and will fluoresce a strong green to blue-green under both short-and long-wave ultraviolet light.
