Noun

arizonite (usually uncountable, plural arizonites)

1. (mineralogy) A titanate of iron, Fe₂Ti₃O₉.
   • 1909, Chase Palmer, "Arizonite, Ferric Metatitanate", The American Journal of Science, 4th Series, Vol. XXVIII, No. 166, p. 355:

     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.
   • 1878, Richard Josiah Hinton, The Handbook to Arizona, pp. 96–97:

     Silver occurs, native, in various lodes... The Sumner lode produces a new combination of ore. The principal vein matter is micaceous iron, iodide of silver, gold, sulphurets of iron, and antimony. The name Arizonite has been given to it by Mr. H. G. Hanks, of San Francisco.
