Although pallasites are a rare meteorite type, enough pallasite material is found in museums and meteorite collections and is available for research. This is due to several large finds, some of which yielded more than a metric ton. The following are the largest finds: Brenham, Kansas, United States.
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).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. Dante Lauretta, a professor of Planetary Science and Cosmochemistry at the University of Arizona.
The stony-irons are divided into mesosiderites and pallasites. Pallasites have a matrix of meteoric iron with embedded silicates (most of it olivine). [2] Mesosiderites are breccias which show signs of metamorphism. The meteoric iron occurs in clasts instead of a matrix. [3] [4]
Telluric iron is an extremely rare metal, found only in a few places in the world. Like meteorites, the very coarse Widmanstätten structures most likely develop through very slow cooling, except that the cooling occurred in the Earth's mantle and crust rather than in the vacuum and microgravity of space .

It is a pallasite, a type of stony–iron meteorite that when cut and polished shows yellowish olivine (peridot) crystals. In 1951 a farmer uncovered a meteorite in an unknown location near Esquel while digging a hole for a water tank. The meteorite was purchased from the finders and taken to the United States in 1992 by meteorite expert Robert ...
Caballero's photo shows a Bryde's whale about to devour a baitball in Baja California Sur, Mexico. "The image captures perhaps the most special — and craziest — moment of my life," Caballero said.
Almost all pallasite meteorites are part of the pallasite main group. [1] References This page was last edited on 27 July 2023, at 14:47 (UTC). Text is ...
