About Ferroalluaudite
Formula:
(Na,Ca)Fe2+(Fe3+,Mn2+,Fe2+)2(PO4)3
Colour:
Straw-yellow to brownish yellow, green, greenish black; yellow to yellow-green in transmitted light.
Hardness:
5 - 5½
Specific Gravity:
3.4 - 3.5
Crystal System:
Monoclinic
Member of:
Name:
In allusion to the composition, containing dominant iron (Latin = FERRum) and Alluaudite in allusion to its relationship to that species.
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).
