Seymchan meteorite. Magnificently polished mirror-like surface, translucent olivines. Schreibersite inclusion.

Seymchan is a pallasite meteorite found in the dried-up bed of the Hekandue River, a left tributary of the Jasachnaya River in the Magadan district of Russia, near the settlement of Seymchan, in June 1967.

The main mass, weighing 272.3 kilograms (600 lb), was discovered during a survey conducted in June 1967 by geologist F.A. Mednikov. The mass was a triangular, thumbprint-shaped meteorite lying among the stones in the streambed. A second specimen, weighing 51 kilograms (112 lb), was found with a mine detector 20 meters from the first in October 1967 by I.H. Markov. The main mass was entrusted to the USSR Academy of Sciences.

During a subsequent expedition in 2004, Dmitri Kachalin recovered approximately 50 kilograms of new material. Remarkably, about 20% of the new specimens contained olivine crystals, revealing the siliceous nature of the meteorite. The pallasitic structure had not yet been discovered in studies of small sections of the original mass, which consisted 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 an anomalous coarse octahedrite IIE. Seymchan is considered a stable and rust-resistant pallasite.
