P.A. Williams, in Encyclopedia of Geology (Second Edition), 2005 Secondary Tungstates. Scheelite is also well known as a secondary mineral, especially associated with the oxidation of ferberite and hu bnerite. In this setting, it also may incorporate molybdate in its lattice. Other secondary tungstates are rare, with perhaps the most frequently encountered species being …

With scheelite's high dispersion and refractive indices (RI), the right gem design can create lively, sparkly gems with high brilliance. They occur in a wide variety of colors, too. However, the combination of low hardness (4.5-5), distinct and good cleavage, and brittle tenacity makes scheelites poor choices for jewelry use. Nevertheless ...

Scheelite is often found to have a grayish white color; yellowish, brownish or translucent (Figure 1). Its streak is white. Scheelite has a greasy luster which helps distinguish it. Moreover, when looking for scheelite, miners use ultraviolet light which causes it to fluoresce with a bright blue color. Many prospectors for scheelite have made ...

The association between gold and scheelite in orogenic gold deposits has long been recognized. Goldfarb et al. review the characteristics of orogenic gold deposits.In many deposits, scheelite predates and/or is contemporaneous with gold deposition, such as in the Val-d'Or district, Canada (Beaudoin and Pitre 2005), at Mt. Charlotte, Australia (Mueller 1991) or …

Scheelite is an important ore mineral, and is well-known among collectors for its distinctly colored crystals associated with brilliant fluorescence.It forms a series with the rarer mineral Powellite, which contains molybdenum in place of the tungsten.Scheelite is named after the Swedish chemist Karl Wilhelm Scheele (1742-1786). Scheele is credited with the discovery of tungsten …

Scheelite is the main ore mineral in skarn-type tungsten deposits, and a common accessory mineral in a variety of rock-types. The Baoshan deposit in South China is one of the most important polymetallic scheelite skarn deposits in China, hosting 40,000 t of WO 3 with economic concentrations of Zn, Cu, and Ag. It is hosted by a calcic skarn that is zoned …

Electrochemical reduction of CO 2 to high-value chemical feedstocks, such as formate, is one of the most promising ways to alleviate the greenhouse effect. Unfortunately, the exploration of electrocatalysts with high activity and selectivity over a wide potential window (especially low potential for high current density) still remains a grand challenge.

Scheelite is an important metallic mineral in W-related hydrothermal deposits and can be utilized as a reliable geochronometer to directly date the timing of mineralization. Up to now, two previous studies have performed in situ U–Pb dating of scheelite using NIST glasses as reference materials due to the lack of scheelite standards. However ...
