Ferroericssonite
Ferroericssonite is an IMA-recognized mineral species in the silicate class, with the chemical formula BaFe²⁺₂Fe³⁺(Si₂O₇)O(OH).
It crystallizes in the monoclinic crystal system (space group C2/m). It is a member of the Ericssonite structural group.
Key properties: Mohs hardness 4.5; Brown streak; Vitreous luster; optically biaxial.
IMA symbol Fers, IMA status: approved, named in 2010.
Along cleavage planes of altered gillespite in quartz-sanbornite veins.
It is found associated with Anandite, bazirite, celsian, devitoite, quartz, titantaramellite.
As the Fe2+ analogue of ericssonite.
