[After Autun, a city of east-central France.]

autunite

(ˈɔːtəˌnaɪt) n (Minerals) a yellowish fluorescent radioactive mineral consisting of a hydrated calcium uranium phosphate in tetragonal crystalline form. It is found in uranium ores. Formula: Ca(UO2)2(PO4)2.10–12H2O[C19: named after Autun in France, one of the places where it was found, + -ite¹]

au•tun•ite

(ˈɔt nˌaɪt, oʊˈtʌn aɪt)

n. a yellow mineral, a hydrous calcium uranium phosphate, CaU₂P₂O₁₂∙8H₂O, a minor ore of uranium. [1850–55; after Autun, city in E France near source of supply; see -ite¹]

autunite

[ō′tə‚nīt] (mineralogy) Ca(UO₂)₂(PO₄)₂·10H₂O A common fluorescent mineral that occurs as yellow tetragonal plates in uranium deposits; minor ore of uranium.

Autunite

(named after the city of Autun, in Saône-et-Loire Department France), a mineral of the uranite group. Autunite has a chemical formula of Ca(UO₂)₂[PO₄]₂·8H₂O; it contains 62.7 percent UO₃. The mineral crystallizes in the tetragonal system, primarily forming thin tabular, micaceous, or tetragonal crystals. Scaly aggregates also occur. Autunite varies in color from lemon yellow to sulfur yellow; sometimes it is green. The mineral has a pearly luster and is highly radioactive. Its hardness on Mohs’ scale is 2–2.5, and its density is 3,050–3,190 kg/m³. Autunite is formed as a result of surface changes in various uranium minerals (particularly uraninite), in hydrothermal veins, and in pegmatites. It is an ore of uranium.
