Formula:
(CaCa)(Fe3+AlMn3+)O[Si2O7][SiO4](OH)
Member of:
The Fe3+-analogue of piemontite. Chemically similar to ferriakasakaite-(Ce).
Compare also Unnamed (Fe3+-analogue of Piemontite-(Sr)).
Empirical formula: (Ca0.92Mn0.08)Σ1.00(Ca0.53La0.27Pb0.14Nd0.11)Σ1.05(Fe0.45Al0.43)Σ0.88Al1.00(Mn0.60Mg0.17Zn0.12Cu0.11)Σ1.00[Si3.05O11](OH,O)2.
Tentatively called "ferripiemontite".
