Daubréeite
Daubréeite is a rare bismuth oxohalide mineral with formula . It is a creamy-white to yellow-brown, soft, earthy clay–like mineral which crystallizes in the tetragonal crystal system. It is a member of the matlockite group. It was first described for an occurrence in the Constanicia mine, Tazna, Bolivia, in 1876. It was named for French mineralogist Gabriel Auguste Daubrée (1814–1896). At the Tanza location it occurs as a secondary mineral formed by the oxidation of native bismuth or bismuthinite. It occurs with clay minerals. In addition to its discovery location it has also been reported from the Tintic District in the East Tintic Mountains of Juab County, Utah; in the Josephine Creek District of Josephine County, Oregon; in the Manhattan District of Nye County, Nevada; and the Rio Marina Mine on Elba, Italy Italy, officially the Italian Republic, is a country in Southern Europe, Southern and Western Europe, Western Europe.

Gabriel Auguste Daubrée
Gabriel Auguste Daubrée MIF FRS FRSE (25 June 181429 May 1896) was a French geologist, best known for applying experimental methods to structural geology. He served as the director of the École des Mines as well as the president of the French Academy of Sciences. Life Daubrée was born at Metz, and educated at the École Polytechnique in Paris. At the age of twenty he had qualified as a mining engineer, and in 1838 he was appointed to take charge of the mines in the Bas-Rhin (Alsace), and subsequently to be professor of mineralogy and geology at the Faculty of Sciences, Strasbourg. In 1859 he became engineer in chief of mines, and in 1861, upon the death of Louis Cordier, he was appointed professor of geology at the Museum d'Histoire Naturelle in Paris and was also elected member of the French Academy of Sciences. In the following year he became professor of mineralogy at the École des Mines, and in 1872 director of that school. In 1878 Daubrée was elected vice-president ...

Daubréelite
Daubréelite is a rare sulfide mineral. It crystallizes with Cubic crystal system, cubic symmetry and has chemical composition of Fe2+Cr3+2S4. It usually occurs as black platy aggregates. Naming and history Daubréelite was named after the French mineralogist, petrologist and meteoriticist Gabriel Auguste Daubrée. The mineral was first described in 1876 in the ''American Journal of Science''. Its type locality is the Coahuila meteorite, Bolsom de Mapimí, Coahuila, Mexico. Classification In the Nickel-Strunz classification daubréelite is part of the "Sulfides and Sulfosalts" and further a "metal sulfide with a metal-sulfide ratio of 3:4 and 2:3". Occurrences Daubréelite is found in iron meteorites as an inclusion in meteoric iron (kamacite and taenite). Further paragenesis, paragenetic minerals are alabandine, enstatite, graphite, plagioclase and schreibersite. According to one source daubréelite has been described from 34 localities. Some notable examples being the Hoba me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Tintic Mountains
The East Tintic Mountains are a mountain range in central Juab, Utah, and Tooele counties in Utah, United States on the east margin of the Great Basin just west of the Wasatch Front about south-southeast of Salt Lake City. The community of Eureka is an old mining town near the center of the range. U.S. Route 6 Passes through the central part of the range and through Eureka. The Tintic Mining District is located in the central part of the range. The district was an important producer of silver, gold and base metals during the late 19th and early 20th centuries. The mountain range, Tintic Valley, and the mining district are named after Chief Tintic of the Goshute. The Tintic Smelter Site, the Sunbeam Mine, and the Silver City Cemetery, listed on the National Register of Historic Places, preserve some remnants of the district. The Tintic quartzite is named after the Tintic Mountains, where exposures of the formation occur. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bismuth Minerals
Bismuth is a chemical element; it has symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-white color when freshly produced. Surface oxidation generally gives samples of the metal a somewhat rosy cast. Further oxidation under heat can give bismuth a vividly iridescent appearance due to thin-film interference. Bismuth is both the most diamagnetic element and one of the least thermally conductive metals known. Bismuth was formerly understood to be the element with the highest atomic mass whose nuclei do not spontaneously decay. However, in 2003 it was found to be very slightly radioactive. The metal's only primordial isotope, bismuth-209, undergoes alpha decay with a half-life roug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxide Minerals
The oxide mineral class includes those minerals in which the oxide anion (O2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class.
