Norrbotten County, Sweden (original) (raw)

Description: Chemical analysis by A. Bygden of "hollandite" (sensu lato) published in Ödman (1950) gave SiO2: 0.09; TiO2: 0.03; Al2O3: 1.69; Fe2O3: 6.44; MnO:62.18; BaO: 9.14; PbO: 3.25; Na2O: 0.43; K2O: 1.96; H2O<105 degree: 0.06; H2O>105 degree: 1.00; O: 13.14; S:0.01; Insol in 20 % HCL: 0.18; Total 99.60 Material labelled "hollandite" supplied by Ulf Nyberg from this locality was investigated by Cristian Biagione and found to be ferrihollandite (Ulf Nyberg communication 17.3.2013, see the caption of https://www.mindat.org/photo-521824.html)

ⓘ Ferroberaunite

Formula: Fe2+Fe3+5(PO4)4(OH)5 · 6H2O

Description: Beraunite was originally defined as a fully oxidised mineral, but was redefined by Fanfani and Zanazzi (1967), on the basis of a crystal structural analysis, as a mixed-valence iron phosphate and they left the original fully oxidized end-member unnamed. In essence, Fanfani and Zanazzi (1967) had discovered a new mineral species (ferroberaunite) but re-used a previous name. In the 19th century, both beraunite and eleonorite had been applied to the fully oxidized mineral. Eleonorite had been re-applied by the IMA to the oxidized end-member of the beraunite-eleonorite series. In the IMA 21-D redefinition the name beraunite was reapplied to the oxidised phase and the name ferroberaunite was created for the mixed-valence phase (Tvrdy et al., 2021).
