Auvergne; Rhône-Alpes


Ancient fluorite mine. Complex veins with green and violet banded fluorite replaced by quartz and sulphides in the deep parts and extremities of the vein; barite and blue fluorite with mixed-layer illite/smectite is associated.
Early stages of the mineralization show microbrecciated black quartz with arsenopyrite.
Host rocks are gneisses and muscovite quartzites.

135 000 tons of fluorite have been worked out.

Located near Barlet, around 6 km S of Langeac.
The vein is located North of Le Barlet hamlet (path from La Bretogne to Barlet)
