Among the meteorites gathered in the vicinity of the Arizona Meteorite Crater, a few individuals have been found whose etching pattern differs markedly from that of the typical Canyon Diablo irons; and chemical analysis reveals a considerably higher content of nickel: about 8.4%. According to accepted methods of identification, these distinctive individuals are regarded as belonging to a different type of meteorite. The majority of the irons of this new type show striking deformation of the kamacite plates, a feature almost unknown in the usual Canyon Diablo irons. An explanation for this is offered. It is suggested that the new type of nickel‐iron meteorite from the region of Meteorite Crater be called Canyon Diablo, Arizona, No. 2.
