Hi there, I am selling this Amazing Seymchan Pallasite Iron Meteorite Specimen. This meteorite was discovered in Russia in 1967. This piece has been cut, polished, and etched to reveal its natural crystalline structure called the Widmanstatten pattern. The Widmanstatten pattern is a crystal structure that occurs only in iron-nickel meteorites. For this to form the parent body has to be large enough that most of it's metal content melted and sank to the core, then slowly cooled over millions of years. Then at some point, this large body was destroyed and shattered, eventually raining pieces of itself down on Earth. When you hold this piece in your hand, you are holding the core of a small planet that no longer exists! This piece would make a great display specimen for a collection but its unique shape would also be perfect for making into a piece of extraterrestrial jewelry!  If you have any questions do not hesitate to ask me. Thanks so much for visiting my store and have a great day!

History[edit]
The main mass of 272.3 kilograms (600 lb) was found during a survey in June 1967 by geologist F. A. Mednikov. The mass was a triangular-shaped thumbprinted meteorite lying among the stones of the brook bed. A second specimen of 51 kilograms (112 lb) was found with a mine detector at a distance of 20 m from the first in October 1967 by I. H. Markov. The main mass was turned over to the Academy of Sciences of the USSR.
During a new expedition in 2004, Dmitri Kachalin recovered about 50 kilograms (110 lb) of new material. Remarkably, about 20% of the new specimens were found to contain olivine crystals,[2] and so revealed the silicated nature of the meteorite. The pallasitic structure was not previously discovered during studies on small metal-only sections of the original mass.
Composition and classification[edit]
Seymchan, Pallasite, PMG.
Seymchan belongs to Main Group pallasites, but it is considered anomalous due to its high Iridium content.[3] 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.
Specimens[edit]
Due to the heterogeneous structure of Seymchan, there are two types of specimens: with or without olivine crystals. It is worthy to note that the specimen pictured to the left shows an interesting, seldom seen feature of iron meteorites. The Widmanstätten pattern on the left hand side of the specimen is visibly bent. This is caused by the shearing of the meteorite as it broke up during atmospheric entry and serves as testimony of the violent experience a meteor is subject to as it falls through the atmosphere.
