Carrière de Beauvoir, Échassières, Ébreuil, Allier, Auvergne, France
Active, huge kaolinite quarry in albite-lepidolite granite ('Beauvoir granite'), albitites and greisens. Located NW of the La Bosse mine, about 2 km ESE of Echassières.
The mineralogy is similar to that of the nearby Les Montmins Mine, except that arsenates are extremely rare in the quarry.
Excellent wavellite and variscite come from here.
Access is prohibited (only during working hours?).
