System:IsometricColour:Pale to bright yellow, ...
Name:In allusion to the composition, containing FERRIc iron (Fe3+), and TUNGSTen.


A cubic mineral closely related to the Pyrochlore Group. See also Alumotungstite. A "hexagonal" tabular variety may represent a separate species (Walenta, 1999).
Compare also phyllotungstite, pittongite and elsmoreite.

A rare secondary mineral occurring as an alteration coating on, or replacing, primary tungsten minerals.
