wolframite is frequently found in veins

Wolframite QuotedData

(Fe,Mn)WO4: Iron manganese tungstate mineral commonly found in veins associated with granitic intrusionsMost 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 mWolframite an overview | ScienceDirect Topics

Wolframite Wikipedia

Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich) Along with scheelite, the wolframite series are the most important tungsten ore minerals Wolframite is found in quartz veins and pegmatites associated with granitic intrusivesAssociated minerals include cassiterite, scheelite, bismuth, quartzGood specimens of wolframite are hard to find, and collectors count it as a highly desirable mineral Tungsten ore is mined mostly in quartz veins and areas with granite intrusions, and is used for many everyday objects, thanks to its heaviness and ability to conduct heat Wolframite is made up of iron, manganese, and tungsten oxideWolframite | Material Sourcing

Wolframite, another name for the hübneriteferberite series of manganese/iron tungstates, is perhaps the most important ore of tungstenThese minerals have a structure, unlike that of the other tungstates, based on WO 6 octahedra— ie, each tungsten atom is surrounded by six oxygen atoms arranged at theIn most mineralized quartz veins, wolframite has a homogeneous major element composition over large distances, which can be attributed to a relatively uniform composition of the fluids 8 Different generations of wolframite were found in the Carris and Vale das Gatas minesGeochemistry of cassiterite and wolframite from tin and
