Le Burg Mine , Alban - Le Fraysse area, Tarn, Occitanie, France
The Le Burg Mine, near Tarn, in France’s Mid-Pyrenees has been a one of the most important localities for specimen-quality fluorite in all of Europe over the last 75 years or so. Most specimens are blue in color and are typically associated with quartz and chalcopyrite; however, specimens of yellow, green, yellow/orange, yellow/blue, etc. do occur. The mine was operated hundreds of years ago for copper, lost to time, then rediscovered in 1945 and actively mined for fluorite from 1954 until it finally closed in 2006 (Kosnar, 2013).
