Galena, Pyrite, Quartz, Scheelite, Sphalerite

 

This sample contains some common minerals such as pyrite and quartz, and some valuable ore minerals. Galena, sphalerite, and scheelite are ore minerals for lead, zinc and tungsten respectively. Since galena and sphalerite are more common and appear in many of the other samples in this collection, this description will focus mainly on the mineral scheelite.

Scheelite is an important ore mineral for tungsten. It is very nice to look at under short wave ultraviolet light due to its fluorescence. It can be many different colours, but it is always somewhat translucent if not transparent and when in good crystal form can be used as a gemstone.

Tungsten, the commodity that scheelite is mined for, is a rare metal on earth. It is known for having the highest melting and boiling points of any element discovered. It has many industrial uses that make use of its special properties including filaments in light bulbs and in x-ray tubes. It is a shiny steel grey metal with a high specific gravity like gold.

This specimen is from the Cariboo Hudson Gold Mine in the Cunningham Creek are near the gold mining ghost town of Barkerville, B.C. At this mine work has been done since at least 1938 when an assay reported high levels of gold.
