Bonhams expected to fetch US$2,000,000, but the lot remained unsold. In April 2008, Bonhams offered the main mass for auction at their Manhattan auction. Search for other: Main group pallasites, Metal-rich meteorites, and Pallasites. Currently unclassified, it’s called the Golden Pallasite because this meteorite has a unique patina that appears to glitter like gold in the sunshine. Abbreviation: There is no official abbreviation for this meteorite. Marvin Killgore holds an additional section weighing the same amount, as well as the balance of the main mass. You won’t find this meteorite listed in the Meteoritical Bulletin, but it’s an authentic pallasite found in Northwest Africa in 2021. Specimens Ī section weighing 31 kilograms (68 lb 4.9 st) of type specimen is on deposit at the University of Arizona. When cut and polished, pallasites reveal translucent crystals, which are naturally green in color but sometimes acquire yellow, gold, or brown hues as a result of terrestrial weathering. Oxygen isotopes: δ 18O 2.569 ‰, δ 17O 1.179 ‰, ∆1 7O = −0.157 ‰. Perhaps the most beautiful of all meteorites, pallasites contain abundant olivine suspended in a nickel-iron matrix. Vermicular sulfide ( troilite) is present in some olivine. The metal matrix is mostly kamacite with an average nickel content of 6.98 wt%. The main mass contains several regions of massive olivine clusters up to eleven centimetres (4.3 inches) in diameter with thin metal veins. The olivines vary in shape from rounded to angular, many are fractured and they range in size from less than five millimetres to several centimetres. The Fukang pallasite contains large, gem quality olivine, or peridot, in a nickel- iron matrix. Lauretta and a team of research scientists including Dolores Hill, Marvin Killgore, Daniella DellaGiustina, and Dr. They are thought to originate at the core-mantle boundary of differentiated. Pallasites are characterized by a unique matrix of the mineral Olivine. A slice of the Esquel pallasite, clearly showing the large olivine crystals suspended in the metal matrix. Subsequently, the mass was investigated at the Southwest Meteorite Center, Lunar and Planetary Laboratory, University of Arizona in Tucson, Arizona by Dr. Pallasites are considered by many to be the most beautiful type of meteorite. The specimens were identified as pallasites, a rare class of stony-iron meteorites. The pallasites are a class of stonyiron meteorite. Dante Lauretta, a professor of Planetary Science and Cosmochemistry at the University of Arizona.

He removed about 20 kilograms (44 lb) from the main mass, and in February 2005, the meteorite was taken to the Tucson Gem and Mineral Show, where it was seen by Dr. In 2000, near Fukang, China, a Chinese dealer obtained a mass from Xinjiang Province, China, with a weight of 1,003 kilograms (2,211 lb).
