Related to scheelite: tungsten


 (shā′līt′, shē′-)
A variously colored mineral, CaWO4, found in igneous rocks and used as an ore of tungsten.

[After Carl Wilhelm Scheele.]


(Minerals) a white, brownish, or greenish mineral, usually fluorescent, consisting of calcium tungstate in tetragonal crystalline form with some tungsten often replaced by molybdenum: occurs principally in contact metamorphic rocks and quartz veins, and is an important source of tungsten and purified calcium tungstate. Formula: CaWO4
[C19: from German Scheelit, named after Karl Wilhelm Scheele (1742–86), Swedish chemist]


(ˈʃeɪ laɪt, ˈʃi-)

a mineral, calcium tungstate-molybdate, Ca(WO4MoO4), occurring in crystals and aggregates: an ore of tungsten.
[1830–40; < German Scheelit= Karl Wilhelm Scheele (1742–86), Swedish chemist, who first isolated tungstic acid + -it -ite1]
