Liguowuite
Liguowuite is an IMA-recognized mineral species in the tungstate class, with the chemical formula WO₃.
It crystallizes in the monoclinic crystal system (space group P2_1/n). It is a member of the Perovskite structural group.
Key properties: Mohs hardness 3–4; specific gravity 7.22; White streak; Greasy luster.
IMA status: approved, named in 2021.
Rare in heavy mineral concentrates from hydrothermally (high temperature) altered biotite-quartz monzonite.
It is found associated with Hornblende, pargasite, ferro-hornblende, annite, hydrobiotite, phlogopite, orthoclase, microcline, albite, quartz, kaolinite, ilmenite, goethite, hematite.
The mineral was named to honor Li Guowu (b. 1964) for his contributions to mineralogical research in this region, including the descriptions of tewite and wumuite.
