About FerrihollanditeHide

Formula:

Ba(Mn⁴⁺₆Fe³⁺₂)O₁₆

Colour:

Greyish-black, black

Lustre:

Metallic

Hardness:

4 - 6

Crystal System:

Monoclinic

Member of:

Coronadite Group > Hollandite Supergroup

Name:

Named in 2013 by C. Biagioni, C. Capalbo, M. Lezzerini, M. Pasero for being the ferric iron analogue of hollandite.

Type Locality:

ⓘ Kajlidongri Mine, Jhabua District, Madhya Pradesh, India

Isostructural with:

Coronadite, Cryptomelane, Hollandite, Manjiroite, Strontiomelane

The Ba-Fe³⁺ end-member in the Coronadite Group was redefined as ferrihollandite (IMA 11-F; Biagioni et al., 2013).
The original type locality for hollandite is now that of ferrihollandite.

Possibly the Mn analogue of UM2003-09-O:BaFePbTi (assuming similar structure).

Crystallography of FerrihollanditeHide

Crystal System:

Monoclinic

Class (H-M):

2/m - Prismatic

Cell Parameters:

a = 10.0001(7) Å, b = 5.7465(4) Å, c = 9.8076(8) Å

Ratio:

a:b:c = 1.74 : 1 : 1.707

Unit Cell V:

563.56 Å³

Morphology:

Prismatic and usually striated along [010], probably as a consequence of twinning on {101} or {101}, owing to the pseudo-tetragonal symmetry.

Twinning:

Twinning on {101} or {101}.

Comment:

Space group P2/n. Pseudo-tetragonal. Data from Biagioni et al. (2014).
