Name:
Named in 1821 by Karl Caesar von Leonhard in honor of Carl Wilhelm Scheele [December 9, 1742, Stralsund, Pomerania, Sweden - May 21, 1786, Köping, Sweden], Swedish experimental chemist and commercial apothecary. His experimental work was monumental for the time period and he discovered chlorine and experimented with oxygen before Joseph Priestley recognized it as an element. He investigated many fundamentally important organic compounds. He proved the existence of tungstic oxide in the mineral now bearing his name in 1781.
Isostructural with:
Powellite-Scheelite Series.

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.

Fluorescence of ScheeliteHide

Inherently brightly fluorescent (SW UV & X-rays). Pure end-member material ubiquitously fluoresces bright blue-white (SW UV), but even a small amount of Mo substituting for W produces a creamy yellow fluorescence (SW UV), becoming more yellow with increasing % of Mo. A moderate Fe content can quench the fluorescence. It usually has no response to LW UV but some specimens will fluoresce pink to this band.

Other InformationHide

Thermal Behaviour:
Thermoluminescent.
Notes:
Decomposed by HCl or HNO3, leaving a yellow powder of hydrous tungstic oxide, which is soluble in ammonia.

Alters to Tungstite, Hydrotungstite, or Cuprotungstite.

Replaced by Wolframite as perfect pseudomorphs. Often replaces Wolframite.
Pseudomorphs of Quartz, Kaolinite, and Bismutite after Scheelite have been noted.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
Industrial Uses:
Ore of tungsten
