About Wolframite GroupHide

Note: "Wolframite" usually has a chemical composition covering the range between Hübnerite and Ferberite. Rarely, "wolframite" could also correspond to other, visually very similar members of the wolframite group.


Unique IdentifiersHide

Mindat ID:
39780
Long-form identifier:
mindat:1:1:39780:5

Classification of Wolframite GroupHide

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
B : With medium-sized cations; chains of edge-sharing octahedra
