Wolframite is a series between two minerals; Huebnerite and Ferberite. Huebnerite is the Manganese rich end member while Ferberite is the iron rich end member. Wolframite is the name of the series and the name applied to indistinguishable specimens and specimens intermediate between the two end members. Most specimens found in nature fall within 20 – 80% range of the series and these are termed Wolframites. Only if they are more pure than 80% manganese are they called Huebnerite and conversely if they are 80% iron they are called Ferberite.
