Лот 40 | GIBEON METEORITE — END PIECE
Оценочная стоимость
$ 1 000 – 1 500
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 different irons. This latticework, referred to as a Widmanstätten pattern, is a product of the solid-state intergrowth of two different iron-nickel minerals: kamacite (the low-nickel variety) and taenite (the high-nickel variety). Gibeon meteorites are known for their robust fine octahedral crystalline structure and the current offering is a choice example. The reverse of this vaguely acorn-shaped specimen evidences a good deal of character with its furrows and crests blanketed in an oxidized patina.
Christie's would like to thank Dr. Alan E. Rubin at the Institute of Geophysics and Planetary Physics, University of California, Los Angeles for his assistance in preparing this catalogue.
