	Calaverite - Wikipedia, the free encyclopedia
		Calaverite, or gold telluride, is an uncommon telluride of gold; it is a metallic mineral.
		Calaverite occurs as monoclinic crystals, which do not possess cleavage planes.
		Calaverite occurrences include Cripple Creek, Colorado; Calaveras County, California, USA (from where it gets its name); Nagyag, Romania; Kirkland Lake Gold District, Ontario; Rouyn District, Quebec; and Kalgoorlie, Australia.

		Calaverite is a crystalized gold ore, containing a bit of silver and tellurium.
		Elemental gold is typically either found as gold, as an alloy with other metals such as silver and copper, and as trace amounts in a few minerals.
		Warning, calaverite should not be used in making elixirs due to the presence of tellurium.

	Identification of Tellurides
		Sylvanite, calaverite and krennerite are so nearly identical in composition that on many specimens the usual etch and microchemical tests described in Bulletin 825 will not differentiate between them.
		Calaverite gives a good microchemical test for silver with potassium mercuric thiocyanate, but the reaction with potassium bichromate may be negative.
		Sylvanite-(Au, Ag)Te Color, silvery-white to creamy-white, lighter than calaverite; hardness C. Strongly anisotropic, with multiple twinning; polarization colors light gray, brownish-gray, dark gray.

		Due to its relative chemical inertness gold is usually found as the native metal sometimes as large nuggets, but usually as minute grains in minerals, typically quartz (usually as veins), or sulfide minerals most commonly, pyrite, chalcopyrite, galena, sphalerite, arsenopyrite, stibnite and pyrrhotite or associated with these minerals.
		Gold more rarely occurs with tellurium in the minerals petzite, calaverite, sylvanite, muthmannite, nagyagite and krennerite.
		Gold is widely distributed in the earth's crust at a background level of 0.03 g/1000 kg (0.03 ppm).
