Abellaite is a hydrous carbonate mineral discovered in the abandoned Eureka uranium mine in Catalonia, Spain, with the formula NaPb(CO)(OH).
 It is named in honor of Joan Abella i Creus, a Catalan gemmologist who has long studied minerals from the Eureka mine and first found abellaite in the mine.
 A team composed of Joan Viñals and Xavier Llovet from the University of Barcelona, Jordi Ibáñez-Insa and Josep Elvira from the Institute of Earth Sciences Jaume Almera, and Núria Oriols, from the National Museum of Art of Catalonia identified the mineral’s structure.
Kainite (KMg(SO)Cl·3HO) is an evaporite mineral in the class of "Sulfates (selenates, etc.) with additional anions, with HO" according to the Nickel-Strunz classification.
 It is a hydrated potassium-magnesium sulfate-chloride, naturally occurring in irregular granular masses or as crystalline coatings in cavities or fissures.
 This mineral is dull and soft, and is colored white, yellowish, grey, reddish, or blue to violet.
 Its name is derived from Greek καινος [kainos] ("(hitherto) unknown"), as it was the first mineral discovered that contained both sulfate and chloride as anions. Kainite forms monoclinic crystals.
Bonaccordite is a rare mineral discovered in 1974.
 Its chemical formula is NiFeBO and it is a mineral of the ludwigite group.
 It usually crystallizes in long, cylindrical prisms that form within another source.
 It is named after the area of Bon Accord, where it was first found.
 There have also been findings of bonaccordite within nuclear plants at multiple companies.
 It builds up a deposit within the machines and is a very hard mineral to clean out because it is resistant to ordinary techniques.
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.
Leo Szilard ( ; Hungarian: "Szilárd Leó" ; ] ; German: "Leo Spitz" until age 2; February 11, 1898 – May 30, 1964) was a Hungarian-born physicist and inventor.
 He conceived the nuclear chain reaction in 1933, patented the idea of a nuclear reactor with Enrico Fermi in 1934, and in late 1939 wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb.
Scandiobabingtonite was first discovered in the Montecatini granite quarry near Baveno, Italy in a pegmatite cavity.
 Though found in pegmatites, the crystals of scandiobabingtonite are sub-millimeter sized, and are tabular shaped.
 Scandiobabingtonite was the sixth naturally occurring mineral discovered with the rare earth element scandium, and grows around babingtonite, with which it is isostructural, hence the namesake.
 It is also referred to as scandian babingtonite.
 The ideal chemical formula for scandiobabingtonite is Ca(Fe,Mn)ScSiO(OH).
Colimaite, the naturally occurring analog of synthetic KVS, is a sulfide mineral discovered in southwestern Mexico.
 The potassium-vanadium sulfide was collected from the crater of the Colima volcano.
 The mineral colimaite is named after the locality of this volcano and has been approved in 2007, along with its mineral name, by the Commission on New Minerals, Nomenclature and Classification (CNMNC).
 It has been given the International Mineralogical Association number of IMA 2007-045.
Sincosite is a green mineral discovered in 1922.
 It is named for Sincos, Daniel Alcides Carrión Province, Peru, where it was first discovered.
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.
Markeyite, a uranyl carbonate mineral discovered in the Markey Mine in Utah, USA.
 A group led by Anthony R. Kampf, a mineralogist at the Natural History Museum of Los Angeles County, USA discovered its structure.
