 surtout mamtenant de I'amblj'gonite (phosphate d'alumine et fluorure double de 

 soude et de lithine) qui est utilisee pour la preparation des sels de lithine. Cette 

 substance est accompagnee d'apatite et de plusieurs mineraux rares, tels que le

Tin ores were discovered at Vaulry (Creuse) in 1S12 and exploited by the 

 government but given up in the '60's. Veins carried much columbite wolframite, 

 mispickel, iron-arsenate, native copper, black oxide of copper, moljbdenito, uranium- 

 phospliate, fiuorite, calcium phosphate, and barite.
