Formula:

(Fe3+,Fe2+,M)8+x(OH,H2O)9(H2O)2(PO4)5, M = Fe3+, Cu2+ or other metal cation, x ~ 0.1.

Specific Gravity:

3.37 (Calculated)

Crystal System:

Orthorhombic

Name:

Presently unnamed mineral originally described by Moore (1970) and structurally characterised by Kolitsch (2004); paucity of material hinders submission to IMA. Not identical with the original laubmannite, the type specimen of which was later discredited as a mixture of dufrénite, kidwellite and beraunite.
