Canyon Diablo A Bona Fide Rock From Space with Internal and External Structure Revealed
Meteor Crater, Coconino County, Arizona
This free-standing sculptural end piece exhibits the internal structure and external features of a quintessential Canyon Diablo iron meteorite. The cut surface clearly reveals its crystalline structure; a circular graphite nodule (see previous lot) and iron sulfide inclusions are also in evidence.
As the different alloys which comprise iron meteorites require extended cooling curves to crystallize, and as the opportunity for such extended cooling occurs only in the vacuum of outer space, the crystalline latticework seen here is diagnostic in the identification of iron meteorites, and different meteorites exhibit different patterns (see lots 13, 20 and 52).
Contrasting dramatically with the petroglyph-like internal structure are the arches of its exterior surface. The internal and external features of this meteorite are fully revealed in this select example of Canyon Diablo, the quintessential American meteorite. Significantly, an image of this specimen appears on page 123 in what is the bible for the contemporary meteorite enthusiast, O. Richard Nortons Rocks From Space. A pristine, first edition copy of Rocks From Space autographed by the author accompanies this choice specimen.(2)
