Mine du Burg (Mine du Burc), Région d'Alban et du Fraysse, Tarn, Midi-Pyrénées, France
A large fluorite vein (1200m in long and 3m in width), hosted in cambrian black schists. As all fluorite deposits in Tarn, this one is composed of blue fluorite with quartz and siderite. It is well known for its nice blue and/or yellow fluorite crystals on quartz.
The vein was mined during antiquity (for copper) but was only rediscovered in 1945 and operated (for fluorite) from 1954 until April 2006. During the operation up to 290m depth, 650,000 tons of fluorite were worked out. It was the last fluorite mine in France...
