Vulcanite
Vulcanite is a rare copper telluride mineral. The mineral has a metallic luster, and has a green or bronze-yellow tint. It has a hardness between 1 and 2 on the Mohs scale (between talc and gypsum). Its crystal structure is orthorhombic. Vulcanite is named for the place where it was discovered in 1961, the Mammoth Good Hope Mine in Vulcan (ghost town and district), Gunnison County, Colorado. Small deposits have also been discovered in Japan, Russia, Saudi Arabia, and Norway. It occurs with native tellurium, rickardite, petzite, and sylvanite.

Petzite
The mineral petzite, Ag3 Au Te2, is a soft, steel-gray telluride mineral generally deposited by hydrothermal activity. It forms isometric crystals, and is usually associated with rare tellurium and gold minerals, often with silver, mercury, and copper. The name comes from chemist W. Petz, who first analyzed the mineral from the type locality in Săcărâmb, Transylvania, Romania in 1845. It was described by Wilhelm Karl Ritter von Haidinger in 1845 and dedicated to W. Petz who had carried out the first analyses. It occurs with other tellurides in vein gold deposits. It is commonly associated with native gold, hessite, sylvanite, krennerite, calaverite, altaite, montbrayite, melonite, frohbergite, tetradymite, rickardite, vulcanite and pyrite. Petzite forms together with uytenbogaardtite (Ag3AuS2) and fischesserite (Ag3AuSe2) the uytenbogaardtite group.

Rickardite
Rickardite is a telluride mineral, a copper telluride (Cu7Te5) or Cu3-x (x = 0 to 0.36)Te2. It was first described for an occurrence in the Good Hope Mine, Vulcan district, Gunnison County, Colorado, US, and named for mining engineer Thomas Arthur Rickard (1864–1953). It is a low temperature hydrothermal mineral that occurs associated with vulcanite, native tellurium, cameronite, petzite, sylvanite, berthierite, pyrite, arsenopyrite and bornite.

Orthorhombic Minerals
In crystallography, the orthorhombic crystal system is one of the 7 crystal systems. Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular prism with a rectangular base (''a'' by ''b'') and height (''c''), such that ''a'', ''b'', and ''c'' are distinct. All three bases intersect at 90° angles, so the three lattice vectors remain mutually orthogonal. Bravais lattices There are four orthorhombic Bravais lattices: primitive orthorhombic, base-centered orthorhombic, body-centered orthorhombic, and face-centered orthorhombic. For the base-centered orthorhombic lattice, the primitive cell has the shape of a right rhombic prism;See , row oC, column Primitive, where the cell parameters are given as a1 = a2, α = β = 90° it can be constructed because the two-dimensional centered rectangular base layer can also be described with primitive rhombic axes.

Sylvanite
Sylvanite or silver gold telluride, chemical formula , is the most common telluride of gold. Properties The gold:silver ratio varies from 3:1 to 1:1. It is a metallic mineral with a color that ranges from a steely gray to almost white. It is closely related to calaverite, which is more purely gold telluride with 3% silver. Sylvanite crystallizes in the monoclinic 2/m system. Crystals are rare and it is usually bladed or granular. It is very soft with a hardness of 1.5–2. It has a high relative density of 8–8.2. Sylvanite is photosensitive and can accumulate a dark tarnish if it is exposed to bright light for too long. Occurrence Sylvanite is found in Transylvania, from which its name is partially derived. It is also found and mined in Australia in the East Kalgoorlie district. In Canada it is found in the Kirkland Lake Gold District, Ontario and the Rouyn District, Quebec. In the United States it occurs in California and in Colorado where it was mined as part of the Crippl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunnison County, Colorado
Gunnison County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 16,918. The county seat is Gunnison. The county was named for John W. Gunnison, a United States Army officer and captain in the Army Topographical Engineers, who surveyed for the transcontinental railroad in 1853. History Archeological studies have dated the Ute people's appearance in the Uncompahgre region of Colorado as early as 1150 A.D. Possibilities exist that they are descendants of an earlier people living in the area as far back as 1500 B.C. They were a nomadic people moving about the Western Slope of Colorado in the various parts of the year. In the early to mid-1600s the Spaniards of New Mexico introduced the horse which changed their patterns of hunting taking them across the divide to the eastern slopes and into conflict with the Plains Indians which soon became their bitter enemies. The first recorded expedition of Western Colorado wilderness was led by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
