About FilipstaditeHide

Filipstad

Filipstad, Värmland County, Sweden

Formula:

(Fe³⁺_0.5Sb⁵⁺_0.5)Mn₂O₄

Colour:

Black

Lustre:

Metallic

Hardness:

6 - 6½

Specific Gravity:

4.9 (Calculated)

Crystal System:

Isometric

Member of:

Ulvöspinel Subgroup > Oxyspinel Group > Spinel Supergroup

Name:

For the town of Filipstad, Sweden, which is near the Långban mine.

Type Locality:

ⓘ Långban Mine, Långban Ore District, Filipstad, Värmland County, Sweden

The Fe³⁺ analogue of tegengrenite.

Chemically somewhat similar to manganoschafarzikite, and melanostibite, garpenbergite.

Crystal structure details:
- ions occupy ⅛ of the octahedral and ½ of the tetrahedral holes of the spinel-type ccp oxygen lattice
- tetrahedral sites are split into 5 subsites, as a result of cation ordering
- octahedral sites are split into 6 subsites, as a result of cation ordering
- unit cell edge is tripled due to cation ordering
- M sites, octahedral, host Sb, part of Mn and Fe, and most of Mg
- T sites host the rest of Mn, Fe, and trace Mg, Zn, and Si
