About MontebrasiteHide

Shaft N° 5

Montebras Mines, Montebras, Soumans, Aubusson, Creuse, Nouvelle-Aquitaine, France

Formula:

LiAl(PO₄)(OH)

Colour:

White, colorless, gray white, very pale brown, pale pink, pale yellow

Lustre:

Sub-Vitreous, Resinous, Greasy, Pearly

Hardness:

5½ - 6

Specific Gravity:

2.98 - 3.04

Crystal System:

Triclinic

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 (King and Foord, 1994).]

Type Locality:

ⓘ Montebras Mines, Montebras, Soumans, Aubusson, Creuse, Nouvelle-Aquitaine, France

Isostructural with:

Amblygonite, Natromontebrasite, Tavorite

Amblygonite-Montebrasite Series. The hydroxyl analogue of Amblygonite.
Montebrasite is, by far, the most common member of the group. Amblygonite is scarce.

Occurs chiefly in granite pegmatites of the lithium- and phosphate-rich type. Crystals may be enormous in size (> 1 m).
