System:MonoclinicColour:Yellow, brownish-yellow, ...
Hardness:5½ - 6
Name:After Francois Alluaud, of Limoges, France, who discovered the Chanteloube material.


Alluaudite Group. Alluaudite-Ferroalluaudite Series.

A confusing change of nomenclature occurred regarding the species in this series. Ferroalluaudite was formerly Alluaudite and the present day Alluaudite was formerly Mangan-Alluaudite.

Occurs as an alteration product of Varulite and Arrojadite-(KFe).
