“Hemispherical radiated crystaline agregate of Scandian Ixiolite. Its empyrical formula is (Nb1.21Ta0.78Sc0.59Fe2+0.49Fe3+0.37Ti0.25Mn2+0.15W0.12Zr0.04)4O8. Note that this ixiolite variety is Nb-dominant and Sn-free. So it is really distinct specie from usual Ta-dominant ixiolite. FOV is ~15x12 mm. Pavel M. Kartashov collection and photo.
