Topaz is a silicate mineral of aluminium and fluorine with the chemical formula Al2SiO4(F,OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden brown to yellow orange. Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.
The Canyon Diablo meteorite refers to the many fragments of the asteroid that created Meteor 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.
Abernathyite is a mineral with formula K(UO2)(AsO4)·3H2O. The mineral is named after Jesse Evrett Abernathy (1913–1963) who first noted it in 1953 in the U.S. State of Utah. It was described as a new mineral species in 1956. Abernathyite is yellow and occurs as small crystals.
Veatchite is an unusual strontium borate, with the chemical formula Sr2B11O16(OH)5·H2O. There are two known polytypes, veatchite-A and veatchite-p.
Mineral collecting is the hobby of systematically collecting, identifying and displaying mineral specimens. Mineral collecting can also be a part of the profession of mineralogy and allied geologic specialties. Individual collectors often specialize in certain areas, for example collecting samples of several varieties of the mineral calcite from locations spread throughout a region or the world, or of minerals found in pegmatites.
Diaboleite is a blue-colored mineral with formula Pb2CuCl2(OH)4. It was discovered in England in 1923 and named diaboleite, from the Greek word διά and boleite, meaning "distinct from boleite". The mineral has since been found in a number of countries.
Magnesiopascoite is a bright orange mineral with formula Ca2Mg(V10O28)·16H2O. It was discovered in the U.S. state of Utah and formally described in 2008. The mineral's name derives from its status as the magnesium analogue of pascoite.
Kyawthuite is a rare mineral with a simple formula: Bi3+Sb5+O4. It is a natural bismuth antimonate. Kyawthuite is monoclinic, with space group I2/c, and is isostructural with clinocervantite, its trivalent-antimony-analogue. Kyawthuite is also an antimony-analogue of clinobisvanite. Kyawthuite was discovered in the vicinity of Mogok in Myanmar, an area famous for its variety of gemstone minerals. Only one sample of the naturally occurring form of this mineral has been found and is stored at the Natural History Museum of Los Angeles County.
Fermiite is a rare uranium mineral with the formula Na4(UO2)(SO4)3·3H2O. Chemically related minerals include oppenheimerite, meisserite (which is also structurally-related to fermiite), belakovskiite, natrozippeite and plášilite. Fermiite comes from the Blue Lizard mine, San Juan County, Utah, USA, which is known for many rare uranium minerals. The name honors Enrico Fermi (1901–1954).
Belakovskiite is a very rare uranium mineral with the formula Na7(UO2)(SO4)4(SO3OH)(H2O)3. It is interesting in being a natural uranyl salt with hydrosulfate anion, a feature shared with meisserite. Other chemically related minerals include fermiite, oppenheimerite, natrozippeite and plášilite. Most of these uranyl sulfate minerals was originally found in the Blue Lizard mine, San Juan County, Utah, US. The mineral is named after Russian mineralogist Dmitry Ilych Belakovskiy.
Meisserite is a very rare uranium mineral with the formula Na5(UO2)(SO4)3(SO3OH)(H2O). It is interesting in being a natural uranyl salt with hydrosulfate (hydroxysulfate) anion, a feature shared with belakovskiite. Other chemically related minerals include fermiite, oppenheimerite, natrozippeite and plášilite. Most of these uranyl sulfate minerals was originally found in the Blue Lizard mine, San Juan County, Utah, USA. The mineral is named after Swiss mineralogist Nicolas Meisser.
Oppenheimerite is a very rare uranium mineral with the formula Na2(UO2)(SO4)2•3H2O. Chemically related minerals include fermiite, natrozippeite, plášilite, belakovskiite and meisserite. Most of these uranyl sulfate minerals were originally found in the Blue Lizard mine, San Juan County, Utah, US. The mineral is named after American Theoretical physicist J. Robert Oppenheimer.
Plášilite is a very rare uranium mineral with the formula Na2(UO2)(SO4)2•3H2O. Chemically related minerals include natrozippeite, belakovskiite, meisserite, fermiite and oppenheimerite. Most of these uranyl sulfate minerals were originally found in the Blue Lizard mine, San Juan County, Utah, US. The mineral is named after Czech crystallographer Jakub Plášil.
Manganoblödite is a rare manganese mineral with the formula Na2Mn(SO4)2·4H2O. Somewhat chemically similar mineral is D'Ansite-(Mn). Manganoblödite was found in the Blue Lizard mine, San Juan County, Utah, US, which is known for several relatively new secondary uranium minerals In the mine, manganoblödite occurs intimately intergrown with manganese-, cobalt- and nickel-enriched blödite and a yet another new mineral - cobaltoblödite. Manganoblödite, as suggested by its name is a manganese-analogue of blödite. It is also analogous to changoite, cobaltoblödite and nickelblödite - all three are members of the blödite group.
Cobaltoblödite is a rare cobalt mineral with the formula Na2Co(SO4)2·4H2O. Cobaltoblödite was found in the Blue Lizard mine, San Juan County, Utah, USA, which is known for secondary uranium minerals. Cobaltoblödite occurs intimately intergrown with manganese-, cobalt- and nickel-enriched blödite and a yet another new mineral - manganoblödite. Cobaltoblödite, as suggested by its name is a cobalt-analogue of blödite. It is also analogous to changoite, manganoblödite and nickelblödite - other members of the blödite group.
Shumwayite is a rare but relatively simple uranyl sulfate mineral with the formula (UO2)2(SO4)2•5H2O. It was discovered in the Green Lizard and Giveaway-Simplot mines of the White Canyon mining district, San Juan County, Utah, US.
Braunerite is a hydrous uranyl carbonate mineral discovered by Jakub Plášil of the Institute of Physics at the Academy of Sciences of the Czech Republic and colleagues in the Svornost mine in the Jáchymov ore district, Western Bohemia, Czech Republic.
Ewingite is a mineral discovered by Jakub Plášil of the Institute of Physics at the Academy of Sciences of the Czech Republic in the Plavno mine, Czech Republic. Travis Olds of the University of Notre Dame and colleagues described ewingite, which is the most structurally complex known mineral on Earth. Ewingite is named in honor of Rodney C. Ewing, Professor of Geological Sciences at Stanford University, USA.
Leószilárdite is a mineral discovered by Travis Olds of the University of Notre Dame and colleagues in the Markey Mine in Utah, USA. They named the mineral in honor of Leó Szilárd, Hungarian-born physicist and inventor. Leószilárdite is the first naturally occurring sodium- and magnesium-containing uranyl carbonate. It is rare and water-soluble, and was discovered on a seam of carbon-rich material deposited by an ancient stream. Groundwater reacted with the uraninite ore to create leószilárdite and other minerals.
Meyrowitzite, Ca(UO2)(CO3)2·5H2O, is a carbonate mineral verified in May of 2018 by the Commission of New Minerals, Nomenclature and Classification of the International Mineralogical Association. It is an extremely rare mineral, discovered in the Markey mine Utah, U.S.A. The mineral is a transparent yellow and has blades up to approximately 0.2 mm in length. It is soluble in water or aqueous solutions. Meyrowitzite is named in honor of Robert Meyrowitz (1916–2013), an American analytical chemist. After serving in WW II, he joined the United States Geological Survey (USGS). He was known for developing innovative new methods for analyzing small and difficult to study mineralogical samples along with his formulation of the high-index immersion liquids.
