Name:
Named by August Breithaupt in 1840 for the town of Beroun (Beraun) near the type locality at the Hrbek Mine, Svatá Dobrotivá (St Benigna), Beroun (Beraun), Bohemia, Czech Republic. Beraunite 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, they had discovered a new mineral species (ferroberaunite; later defined by Tvrdý et al., 2021) but they re-used an existing name for a different composition (beraunite). 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.
A secondary mineral found in bog iron ores and phosphate deposits, plus as a cement in clays, sands, and bone material; also as an alteration product of triphylite in granitic pegmatites.

The name beraunite is now applied only to the fully oxidised species (see redefinition by Vrtiška et al., 2022) and the name ferroberaunite should be applied to the mixed-valence (both Fe2+ and Fe3+) species.
Note: beraunite is always more or less reddish, while ferrobraunite is greenish.

May be confused with acicular oxidised dufrénite and natrodufrénite.

Optical Data of BerauniteHide

Type:
Biaxial (+)
RI values:
nα = 1.707 - 1.775 nβ = 1.735 - 1.786 nγ = 1.738 - 1.820
2V:
Measured: 30° to 60°, Calculated: 66°
Birefringence:
0.031
Max Birefringence:
δ = 0.031 - 0.045
Image shows birefringence interference colour range (at 30µm thickness)
and does not take into account mineral colouration.
Surface Relief:
High
Dispersion:
relatively weak
Optical Extinction:
Y^c = 1.5-5°, Z = b (unoxidized)
Pleochroism:
Visible
Comments:
Colors depend on state of oxidation; The low RI represents beraunite (redefined as mixed valence iron phosphate). Oxidation results in higher refractive indices and approach the original eleonorite.
