Locality type:Mine
Species:'Wolframite' (not an IMA approved species)
Formula:(Fe2+)WO4 to (Mn2+)WO4
Comments:Cooper & Stanley (1990): "Crystals remaining in open voids after the quartz deposition are usually altered to scheelite by subsequent mineralization. It varies in composition from 35 to 55 mole % hübnerite (Beddoe-Stephens & Fortey, 1981; Ball et al., 1985)."
Habit:individual blades up to 20cm, usually embedded in quartz
Validity:Believed Valid
