TitleWolframite with quartz from Cornwall, England
DescriptionHere we see white quartz and dark brown wolframite, (Fe,Mn)WO4. Wolframite is the general name given to a series between two end members: huebnerite (MnWO4) and ferberite (FeWO4). Wolframite is identified by its drab black-gray-brown appearance and its high density. It is an important tungsten ore mineral. This 8 cm long sample is from Cornwall, England.
