ⓘ 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).

Localities: Reported from at least 14 localities in this region.

Habit: The agates are characterized by diverse textures and frequently exhibited concentric zoning patterns. The vein agates most often have a poor-fancy texture pattern.

Colour: red-brownish

Description: The Salmi agates are characterized by specific red-brownish coloration. The colour likely results from chromogenic Fe-oxides compounds disseminated within the agate matrix. The agate nodules often exhibit concentrically zoning patterns. Some of them are characterized by distinct coarse (1−2 cm) and fine (from few micrometres) banding, poor-fancy agate varieties are also widespread. Frequently agates contain large calcite and/or quartz crystals. Aggregations of chlorite inclusions were commonly observed in the contact area to the host rock.[[1]]
