About IxioliteHide

Ixion

Formula:

(Ta,Nb,Sn,Fe,Mn)₄O₈

Colour:

Steel-grey, black

Lustre:

Sub-Metallic

Hardness:

6 - 6½

Specific Gravity:

7.03 - 7.23

Crystal System:

Orthorhombic

Name:

After Ixion in Greek mythology, a character related to Tantalus, in allusion to the tantalum content of the material.

Type Locality:

ⓘ Skogsböle (Skogböle), Kimitoön Island, Kimitoön (Kemiönsaari), Southwest Finland, Finland

Complex oxide with disordered cation distribution (only one cation site in the asymmetric unit) and a unit cell equivalent to a subcell of columbite.

Some "ixiolites" are Nb-dominant and probably a new species (see ixiolite varieties).
Orthorhombic, although some varieties seem to be monoclinic-pseudoorthorhombic (Wise et al., 1998).
