Editing Scheelite (section)

== Occurrence ==
Scheelite occurs in [[Contact metamorphism|contact metamorphic]] [[skarn]]s; in high-temperature [[hydrothermal]] [[Vein (geology)|veins]] and [[greisen]]; less commonly in [[granite]] [[pegmatite]]s.<ref name=Handbook/> Temperature and pressure of formation is between {{convert|200 and 500|°C|sigfig=1}} and from {{Convert|200 to 1,500|bar|psi}}.<ref>Lindgren, W. (1933) ''Ore Deposits of the Western States,'' pp. 518, 535</ref> Typical mineral association includes [[cassiterite]], [[wolframite]], [[topaz]], [[fluorite]], [[apatite]], [[tourmaline]], [[quartz]], [[grossular]]–[[andradite]], [[diopside]], [[vesuvianite]] and [[tremolite]].<ref name=Handbook/>

Scheelite usually occurs in tin-bearing veins; and is sometimes found in association with gold. Fine crystals have been obtained from Caldbeck Fells in [[Cumbria]], Zinnwald/Cínovec and [[Loket (Sokolov District)|Elbogen]] in [[Bohemia]], [[Guttannen]] in [[Switzerland]], the [[Giant Mountains]] in [[Silesia]], [[Dragoon Mountains]] in [[Arizona]] and elsewhere. At [[Trumbull, Connecticut|Trumbull in Connecticut]] and [[Mount Kimpu|Kimpu-san]] in Japan large crystals of scheelite completely altered to wolframite have been found: those from Japan have been called “reinite.”<ref>{{Cite EB1911|wstitle=Scheelite}}</ref> It was mined until 1990 at [[King Island (Tasmania)|King Island]], Australia, [[Glenorchy, New Zealand|Glenorchy]] in [[Central Otago]] and [[Macraes Flat]] in [[North Otago]] and also at The Golden Bar mine at Dead Horse Creek during World War I in [[Nelson, New Zealand]]. There is a high concentration of Scheelite in Northeast of Brazil, mainly in the [[Currais Novos mine]] in Rio Grande do Norte State.<ref>Amstutz, Gerhard Christian et al. (Ed.).
