Description from the seller
Pendentif météorite Seymchan
Seymchan is a pallasite meteorite found in the dry bed of the Hekandue River, a left tributary of the Jasačnaja River in the Magadan District, Russia, near the settlement of Seymchan, in June 1967.
The main mass of 272.3 kilograms (600 lb) was discovered during a survey conducted in June 1967 by geologist FA Mednikov. The mass was a thumbprint-shaped triangular meteorite that lay among the stones in the streambed. A second specimen weighing 51 kilograms was found with a mine detector at a distance of 20 m from the first in October 1967 by IH Markov. The main mass was entrusted to the USSR Academy of Sciences.
During a new expedition in 2004, Dmitri Kachalin recovered about 50 kilograms of new material. Remarkably, about 20% of the new specimens contained olivine crystals, which reveals the siliceous nature of the meteorite. The pallasitic structure had not yet been discovered in studies of small sections of the original mass, composed solely of metal.
Seymchan belongs to the main group of pallasites, but it is considered anomalous due to its high iridium content. Before the discovery of its pallasitic structure, it had been classified as the coarse, anomalous IIE octahedrite. Seymchan is considered a stable and rust-resistant pallasite.
