ⓘ Beraunite
Formula: Fe3+6(PO4)4O(OH)4 · 6H2O
Description: IMA nomenclature revision re-instated eleonorite as the ferric dominant member of the group. 2015. Eleonorite was later defined by Chukanov et al. (2017) as the oxidized end-member of the beraunite-ferrobraunite series (previously also called "oxyberaunite") but is now discredited. Both beraunite and eleonorite had previously been applied to the fully oxidized mineral. Subsequently, Vrtiška et al. (2022), based on a restudy of the type material, redefined beraunite as the oxidised phase and discredited eleonorite.

ⓘ Diadochite ?
Formula: Fe3+2(PO4)(SO4)(OH) · 6H2O
