Mercury minerals

chemical element with symbol Hg and atomic number 80

Moschellandsbergite is a rare isometric mineral made up of a silver-white amalgam of mercury and silver with the chemical makeup Ag2Hg3.

Aktashite is a rare arsenic sulfosalt mineral with formula Cu6Hg3As4S12. It is a copper mercury-bearing sulfosalt and is the only sulfosalt mineral with essential Cu and Hg yet known. It is of hydrothermal origin. It was published without approval of the IMA-CNMNC, but recognized as valid species by the IMA-CNMNC Sulfosalts Subcommittee (2008).

Terlinguaite is the naturally occurring mineral with formula . It is formed by the weathering of other mercury-containing minerals. It was discovered in 1900 in the Terlingua District of Brewster County, Texas, for which it is named. Its color is yellow, greenish yellow, brown, or olive green.

Kleinite is a rare mineral that has only been found in the United States and Germany that occurs in hydrothermal mercury deposits. It occurs associated with calcite, gypsum and (rarely) barite or calomel. Its color can range from pale yellow/canary yellow to orange, and it is transparent to translucent. As a photosensitive mineral, its coloration darkens when exposed to light.

Wattersite is a rare mercury chromate mineral with the formula Hg+14Hg+2Cr+6O6. It occurs in association with native mercury and cinnabar in a hydrothermally altered serpentinite. It was first described from Clear Creek claim, San Benito County, California, USA in 1961. It was named to honor Californian mineral collector Lucius "Lu" Watters.

thumb | right Atheneite is a rare palladium, mercury arsenide mineral with the chemical formula associated with palladium–gold deposits. Its composition parallels that of arsenopalladinite (), isomertieite () and meritieite-II () (Cabral, 2002).

Temagamite is a bright white palladium mercury telluride mineral with a hardness of on the Mohs scale. Its chemical formula is Pd3HgTe3. It was discovered at the Temagami Mine on Temagami Island, Lake Temagami in 1973, and it represents a rare mineral in the Temagami Greenstone Belt.

Mosesite is a very rare mineral found in few locations. It is a mercury mineral found as an accessory in deposits of mercury, often in conjunction with limestone. It is known to be found in the U.S. states of Texas and Nevada, and the Mexican states of Guerrero and Querétaro. It was named after Professor Alfred J. Moses (1859–1920) for his contributions to the field of mineralogy in discovering several minerals found alongside mosesite. The mineral itself is various shades of yellow and a high occurrence of spinel twinning. It becomes isotropic when heated to .

Arquerite is a naturally occurring alloy of silver with mercury. It is a very rare mineral, consisting of a silver-rich variety of amalgam, containing about 87% silver and 13% mercury. Arquerite has been reported from only four localities worldwide, two in Chile and two in British Columbia, Canada. Other names for arquerite include argental mercury, mercurian silver, and silver amalgam.

Danielsite is a sulfide and sulfosalt that was first discovered in a pocket of supergene minerals in the north region of Western Australia. The location found was about west of the locality known as Coppin Pool. The mineral danielsite was named after John L. Daniels who collected the sample in which the new mineral was found. The chemical formula of danielsite is . Danielsite is very fine grained and hard to observe in hand samples. It generally has a gray color with very brittle and soft physical characteristics.

Edoylerite is a rare mercury-containing mineral. Edoylerite was first discovered in 1961 by Edward H. Oyler, whom the mineral is named after, in a meter-sized boulder at the Clear Creek claim in San Benito County, California. The Clear Creek claim is located near the abandoned Clear Creek mercury mine. The material from the boulder underwent several analyses including, X-ray powder diffraction (XRD), a single crystal study, and a preliminary electron microprobe analysis (EMA). Using these analyses it was determined that this was a new mineral but the nature of the material at the time prevente

Daliranite is a sulfosalt found in northwestern Iran with a general chemical formula of PbHgAs2S5. The mineral presents a vibrant orange-red color and fibrous habit which makes it resemble the oxide being confused by its similarities in early studies. Named after Dr. Farahnaz Daliran, who has important contributions to research on ore deposits in Iran, this mineral was accepted by the International Mineralogical Association (IMA) in 2007.
