Pallasite/Mesosiderite
Magadan District, Eastern Russia
Found in 1967 in Seymchan, in Far Eastern Russia, Seymchan was originally believed to be an iron-nickel meteorite but recently olivine crystals were found in parts of some of the Seymchan meteorites, making it a far rarer pallasite. Pallasites are literally gemstones from outer space containing olivine crystals within the iron-nickel matrix. The present large slice exhibits over 50% olivine crystals and silicate inclusions in its iron-nickel matrix and has been polished to reveal this interesting interior, which includes numerous translucent olivine crystals. Silicate inclusions are found in a type of stony-iron meteorite known as a mesosiderite. This unique Seymchan specimen is a mix between a pallasite and a mesosiderite. The olivine crystals in Seymchan are smaller in diameter than in most pallasites. Seymchan slices are remarkably stable.
