Pirate Gold Coins Treasures from Space Meteorite Slice from Russia Sticker $6,000 Seymchan is a pallasite meteorite found in the dry bed of the river Hekandue, a left tributary of river Jasa?naja in the Magadan district, Russia, near the settlement of Seymchan, in June 1967. History 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, 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 Seymchan, Pallasite, PMG. Seymchan belongs to Main Group pallasites, but it is considered anomalous due to its high Iridium content. 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.
