The Ta analogue ofnioboixiolite-(Mn2+).


Unique Identifiers
IMA status notes:
Redefined by the IMA
IMA Formula:
(Ta2/3Mn2+1/3)O2
Approval history:
The old “ixiolite” has been redefined and results now in two distinct mineral species: ixiolite-(Mn2+), with end-member formula (TaMn)O2, and ixiolite-(Fe2+), with end-member formula (TaFe)O2. The type locality for both is Skogsböle, Kimito Island, Finland.

Classification of Ixiolite-(Mn2+)

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
B : With medium-sized cations; chains of edge-sharing octahedra
