Лот 53 | GIBEON METEORITE — CRYSTALLINE LATTICE FEATURED IN END PIECE
Оценочная стоимость
$ 6 000 – 9 000
As the crystalline intergrowth now seen does not appear in terrestrial iron ores, its presence is diagnostic for iron meteorites, and pattern variations are frequently indicative of an origin from a different asteroid. If lots 25 and 62 were cut — which should never occur — they would evidence a pattern similar to what is seen in the lot now offered. This latticework, referred to as a Widmanstätten pattern, is a product of the intergrowth of two different iron-nickel minerals: kamacite (a low-nickel variety) and taenite (a high-nickel variety). The reverse reveals the smoothly undulating natural external surface of the meteorite covered in a light chestnut-hued patina. Gibeon meteorites are known for their robust fine octahedral crystalline structure and this is a choice example.
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.
