Hingganite-(Yb)

Hingganite-(Yb) is an IMA-recognized mineral species in the silicate class, with the chemical formula BeYb(SiO₄)(OH).

It crystallizes in the monoclinic crystal system (space group P2_1/c). It is a member of the Gadolinite structural group.

Key properties: Mohs hardness 6–7; specific gravity 4.83; Vitreous luster; optically biaxial.

IMA symbol Hin-Yb, IMA status: approved, named in 1982.

Formed by very late-stage replacement reactions in \amazonite"-rich pegmatites.

It is found associated with Plumbian microlite [plumbomicrolite], fluorite, keiviite-(Yb), bastnÄasite.

The name refers to the predominance of ytterbium and its relation to hingganite-(Y).
