Wolframite is predominately found in pegmatites and also in quartz veins mostly in combination with granitic intrusives, other minerals like scheelite, bismuth, cassiterite, pyrite, sphalerite, quartz, arsenopyrite and galena constituent a range of Wolframite minerals.
Wolframite is not scientifically classified as an individual mineral species by the IMA.However, it is universally recognized as a mineral series, with the minerals Huebnerite and Ferberite being its end members. Huebnerite is the manganese-rich end .

Tungsten is never found free in nature, but occurs in combination with other metals, notably as tungstate minerals of the scheelite series (solid solution mixture of scheelite CaWO 4 and powellite CaMoO 4 and wolframite series (solid solution mixture of ferberite FeWO 4 and huebnerite MnWO 4), which are the important tungsten ores. These minerals form primary ores with a variety of coproducts ...

Although wolframite b commonly occurs with topaz, locally it may be observed surrounded by quartz, similarly to wolframite a. ... However, the only important occurrences of wolframite c are found in the Mazet veins, while in the Beauvoir greisen and in the La Bosse stockwork, wolframite c is rare. Some evidence does exist showing that during the greisen episode wolframite c may replace earlier ...
(Fe,Mn)WO4: Iron manganese tungstate mineral commonly found in veins associated with granitic intrusions
A primary mineral commonly found as a component of contact-metamorphic tactite; in high-temperature hydrothermal veins and greisen; in granitic pegmatites and medium-temperature hydrothermal veins; in alluvial deposits. Visit gemdat for gemological information about Scheelite.
Wolframite is commonly found in granite and pegmatite dikes, and is often associated with cassiterite; it also occurs in sulfide veins and placer deposits. Because heat causes tungsten to expand at about the same rate as glass, the metal is widely used to make glass-to-metal seals.
Wolframite | Virtual Microscope. Wolframite contains iron, manganese and tungsten and is the main ore mineral of the metal tungsten. It is found at many localities within Cornwall, in veins alongside cassiterite and closely associated with granites. Until the mid-19th century, wolframite was treated just as another impurity mineral or waste ...

Most wolfram and much of the nonalluvial tin in the Slate belt are found in quartz veins, which are commonly less than a meter and rarely more than 2 m wide. These usually occur in sets of spaced parallel veins, commonly steeply dipping with individual veins separated by up to 40 m of host rock. Vein lengths rarely exceed 500 m.
