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.
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]
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.
A unique 4-pound pallasite meteorite featuring crystals of olivine and peridot recently sold for $60,480. ... Meteorites are incredibly rare, with just over 64,000 known meteorites existing in ...
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 .

Seymchan, Pallasite, PMG. Seymchan belongs to Main Group pallasites, but it is considered anomalous due to its high iridium content. [4] Before the discovery of its pallasitic structure it had been classified as IIE anomalous coarse octahedrite. Seymchan is considered a stable and rust-resistant pallasite.
