schee·lite

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

[After Carl Wilhelm Scheele.]

scheelite

(ˈʃiːlaɪt)
n
(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]

scheel•ite

(ˈʃeɪ laɪt, ˈʃi-)

n.
a mineral, calcium tungstate-molybdate, Ca(WO4MoO4), occurring in crystals and aggregates: an ore of tungsten.
