İngilizce dilinde "arizonite" tanımı

noun

1. (mineralogy) A titanate of iron, Fe₂Ti₃O₉.

   • The close ratio of ferric oxide to titanic oxide, viz., 1:3·03, indicates that the mineral is really ferric metatitanate, Fe₂O₃.3TiO₂ or Fe₂Ti₃O₉. Moreover, the crystallographic determinations strengthen the view that this titanate of iron cannot be assigned to any known species, but is entirely new. I propose to name it Arizonite... There appears to be no authentic prior record of the occurrence in nature of a simple ferric metatitanate... Upon readjustment of the analytical data as cited by Rammelsberg, it appears that his mineral consists essentially of 60 per cent ferrous titanate (FeO.TiO₂), ilmenite, and 40 per cent ferric titanate (Fe₂O₃.3TiO₂), arizonite.

2. (historical mineralogy, obsolete) A kind of iron-laden silver ore discovered during Arizona's silver rush in the 1870s.
