Flashcards: Native element minerals

Meteoric iron, sometimes meteoritic iron, is a native metal found in meteorites and made from the elements iron and nickel mainly in the form of the mineral phases kamacite and taenite.

Lonsdaleite (named in honour of Kathleen Lonsdale), also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon with a hexagonal lattice.

Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.

Moissanite (/ˈmɔɪsənaɪt/), is the name given to naturally occurring silicon carbide and to its various crystalline polymorphs.

Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals.

Awaruite is a naturally occurring alloy of nickel and iron with a composition from Ni2Fe to Ni3Fe.

Native copper is an uncombined form of copper which occurs as a natural mineral.

Telluric iron, also called native iron, is iron that originated on Earth, and is found in a metallic form rather than as an ore.

Kamacite is an alloy of iron and nickel, which is found on Earth only in meteorites.

Native tungsten is the mineral form of the metal tungsten, with the accepted name simply tungsten.

Brownleeite is a silicide mineral with chemical formula MnSi.

Octasulfur is an inorganic chemical with the chemical formula S8.

Chaoite, or white carbon, is a mineral described as an allotrope of carbon whose existence is disputed.

Taenite (Fe,Ni) is a mineral found naturally on Earth mostly in iron meteorites.

Icosahedrite is the first known naturally occurring quasicrystal phase.

Cohenite is a naturally occurring iron carbide mineral with the chemical structure (Fe, Ni, Co)3C.

Haxonite is an iron nickel carbide mineral found in iron meteorites and carbonaceous chondrites.

Schreibersite is generally a rare iron nickel phosphide mineral, (Fe,Ni)3P, though common in iron-nickel meteorites.

Auricupride is a natural alloy that combines copper and gold.

Cupalite is a rare mineral which is mostly composed of copper and aluminium, but might contain up to several percent of zinc or iron; its chemical structure is therefore described by an approximate formula (Cu,Zn)Al or (Cu,Fe)Al.

Khatyrkite (pronunciation: /ˈkæti.ərkaɪt/ KAT-ee-ər-kyt) is a rare mineral which is mostly composed of copper and aluminium, but might contain up to about 15% of zinc or iron; its chemical structure is described by an approximate formula (Cu,Zn)Al2 or (Cu,Fe)Al2.

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

Zhanghengite is a mineral consisting of 80% copper and zinc, 10% iron with the balance made up of chromium and aluminium.

Hexamolybdenum, is a molybdenum dominant alloy discovered during a nanomineralogy investigation of the Allende meteorite.

Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic.

Cabriite (Pd2SnCu) is a mineral first found in the eastern Siberian region of Russia and named for the Canadian mineralogist Louis J.

Rosickyite is a rare native element mineral that is a polymorph of sulfur.

Native aluminium (IMA1980-085a) is a natural occurrence of aluminium.

Suessite is a rare iron silicide mineral with chemical formula: Fe3Si.

Native titanium (IMA2010-044) is a natural occurrence of titanium.

Hapkeite is a mineral discovered in the Dhofar 280 meteorite found in 2000 in Oman on the Arabian peninsula.

Qingsongite /ˈtʃɪŋsɒŋaɪt/ is a rare boron nitride mineral with cubic crystalline form.

Roaldite is a rare meteorite mineral containing iron, nickel and nitrogen ((Fe,Ni)4N).

Sinoite is rare mineral with the chemical formula Si2N2O.

Cliftonite is a natural form of graphite that occurs as small octahedral inclusions in iron-containing meteorites, such as Campo del Cielo.

Stibarsen or allemontite is a natural form of arsenic antimonide (AsSb) or antimony arsenide (SbAs).
