Daubréelite
Daubréelite is a rare sulfide mineral. It crystallizes with 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 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 ALH 84001 meteorite, Hoba meteorite, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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-preside ...

Canyon Diablo Meteorite
The Canyon Diablo meteorite refers to the many fragments of the asteroid that created Meteor Crater (also called Barringer Crater), Arizona, United States. Meteorites have been found around the crater rim, and are named for nearby Canyon Diablo, which lies about three to four miles west of the crater. History The impactor fell about 50,000 years ago. Initially known and used by pre-historic Native Americans, Canyon Diablo meteorites have been collected and studied by the scientific community since the 19th century. Meteor Crater, from the late 19th to the early 20th century, was the center of a long dispute over the origin of craters that showed little evidence of volcanism. That debate was largely settled by the early 1930s, thanks to work by Daniel M. Barringer, F.R. Moulton, Harvey Harlow Nininger, and Eugene Shoemaker. In 1953, Clair Cameron Patterson measured ratios of the lead isotopes in samples of the meteorite. Through U-Pb radiometric dating, a refined estimate ...

Coahuila Meteorite
The Coahuila meteorite is a hexahedrite iron meteorite found in Coahuila, Mexico. The large number of fragments has led to many synonyms and many authors think that more than one meteorite is represented by the fragments. Only fragments found in Coahuila, that are hexahedrites and fall into the IIAB group should be called Coahuila meteorite. The mineral Daubréelite was first described in this meteorite.

Alabandine
Alabandite or alabandine is a rarely occurring manganese sulfide mineral. It crystallizes in the cubic crystal system with the chemical composition Mn2+ S and develops commonly massive to granular aggregates, but rarely also cubic or octahedral crystals to 1 cm. Etymology and History Alabandite was first described in 1784 by Franz-Joseph Müller von Reichenstein. The mineral name is derived from its supposed discovery locality at Alabanda (Aïdin) in Turkey. Occurrence Alabandite forms in epithermal polymetallic sulfide veins and low-temperature manganese deposits. It occurs with acanthite, calcite, chalcopyrite, galena, pyrite, quartz, rhodochrosite, rhodonite, sphalerite and native tellurium. Sometimes it was found in meteorites.

Rima Hadley
Rima, also known as Rima the Jungle Girl, is the fictional heroine of W. H. Hudson's 1904 novel '' Green Mansions: A Romance of the Tropical Forest''. In it, Rima, a primitive girl of the shrinking rain forest of South America, meets Abel, a political fugitive. A film adaptation of ''Green Mansions'' was made in 1959 starring Audrey Hepburn. In 1974, the character was adapted into the comic book ''Rima the Jungle Girl'', published by DC Comics. Though ''Rima the Jungle Girl'' ceased publication in 1975, the comic book version of Rima appeared in several episodes of Hanna-Barbera's popular Saturday morning cartoon series, ''The All-New Super Friends Hour'', between 1977 and 1980. Novel Like her literary cousins Tarzan and Mowgli, Rima sprang from an Edwardian adventure novel; in her case, '' Green Mansions: A Romance of the Tropical Forest'', by W. H. Hudson, published in 1904. Hudson was an Argentine-British naturalist who wrote many classic books about the ecology of South Am ...

Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains", "Sea of Tears") is a vast lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant crater to form the flat volcanic plain seen today. The basin's age has been estimated using uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it was originally thought, because later events have altered its surface. Origin Mare Imbrium formed when a proto-planet from the asteroid belt collided with the moon during the Late Heavy Bombardment. The impact i ...

ALH 84001
Allan Hills 84001 (ALH84001) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite–nakhlite–chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars. However, it does not fit into any of the previously discovered SNC groups. Its mass upon discovery was . In 1996, a group of scientists found features in the likeness of microscopic fossils of bacteria in the meteorite, suggesting that these organisms also originated on Mars. The claims immediately made headlines worldwide, culminating in then-U.S. president Bill Clinton giving a speech about the potential discovery. These claims were controversial from the beginning, and the wider scientific community ultimately rejected the hypothesis once all the unusual features in the meteorite had been explained without requiring life to be present.
