Stibiconite was for a long time an acknowledged species, but is now questionable, in line with the revised nomenclature of the minerals of thepyrochlore supergroup (Atencio et al. 2010).
Stibiconite is not, as yet, a discredited mineral and is classified as 'Grandfathered' by the IMA. Full characterization of 'stibiconite' specimens is difficult, requiring full quantification of the oxidation states of Sb for complete characterization to determine whether it is aSb3+ dominant romeite species or a new phase related to known synthetic phasesSb2O5 · 1-3H2O which have been reported to have a pyrochlore structure and contain noSb3+ (Christy & Atencio, 2013).
