Manganflurlite
Manganflurlite is an IMA-recognized mineral species in the phosphate class, with the chemical formula ZnMn²⁺₃Fe³⁺(PO₄)₃(OH)₂(H₂O)₇·2H₂O.
It crystallizes in the monoclinic crystal system (space group P2_1/m). It is a member of the Flurlite structural group.
Key properties: Mohs hardness 2.5; specific gravity 2.73; Buff streak; Vitreous iridescent luster; optically biaxial.
IMA symbol Mflu, IMA status: approved, named in 2017.
A late-stage, relatively low-temperature, secondary hydrothermal mineral in a zoned granitic pegmatite.
It is found associated with Phosphophyllite, hydroxylapatite, jahnsite-(CaMnFe), apatite, mitridatite Zn-bearing rockbridgeite.
The prefix, mangan, indicates the Mn-analog of flurlite.
