Seymchan is a pallasite meteorite found in 1967 in Russia.
The main mass of 272.3 kg was found in June 1967 by the geologist F. A. Mednikov during a survey. The mass was a triangual shaped thumbprinted meteorite lying among the stones of the brook bed. A second specimen of 51 kg was found in October 1967 at a distance of 20 m from the first one by I. H. Markov with a mine detector 1967. The main mass was turned in to the Academy of Sciences of the USSR.
During a new expedition in 2004, Dmitri Kachalin recovered about 50 kg of new material. Remarkably, many of the new specimens (about 20%) were found to contain olivine crystals and so revealed the silicated nature of the meteorite. The pallasitic structure was not discovered previously during studies on small metal-only sections of the original mass.
