Formula:
LiAl(PO
 
4
)(OH)
System:TriclinicColour: White, colorless, gray ...
Hardness:5½ - 6
Member of:Amblygonite Group
Name:Named by Alfred Des Cloizeaux in 1871 for the type locality, the Montebras Mine, Montebras-en-Soumans, Boussac, Creuse, Limousin, France. [Previous attempts by Des Cloizeaux to name montebrasite were rejected as his analyses indicated he had specimens in the amblygonite portion of the F-OH series.]


Amblygonite-Montebrasite Series. The hydroxyl analogue of Amblygonite.
Most members of the Amblygonite-Montebrasite Series have a chemical composition assigning them to montebrasite.

Occurs chiefly in granite pegmatites of the lithium- and phosphate-rich type. Crystals may be enormous in size.
