Ferberite: The wolframite mineral ferberite information

Ferberite is the iron-rich end member of the Wolframite series.It is not always individually distinguished and is sometimes just classified as Wolframite. The presence of iron in its structure is responsible for its black color and opacity in relation to Huebnerite.Ferberite is named after German mineralogist Dr. Moritz Rudolph Ferber (1805-1875).
