Beschreibung:

This complete slice has been etched on one side to show the Widmänstatten crystal pattern in the nickel-iron matrix and polished on the reverse. Found in Montana in 2011, the Choteau meteorite was a single small mass weighing only 8.4 kilograms. The Choteau meteorite is chemically ungrouped, meaning it’s not similar to other known pallasites; it is unique. It is composed of several massive olivine crystal pockets and many smaller crystals set into a nickel-rich matrix. Montana’s only known pallasite, it was cut and prepared with two larger end pieces and a few slices were cut from the center of the meteorite. There is very rarely any material available on the meteorite market. This is a chance to acquire a slice of one of the “unobtainable” pallasites. Christie's would like to thank Dr. Alan E. Rubin at the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles for his assistance in preparing this catalogue. 123 mm x 115 mm x 2 mm (43⁄4 x 4.5 x 1⁄8 in.) 114g.
