Seymchan Pallasite meteorite pendant, engraving of Jesus, unique piece.
Seymchan is a pallasite meteorite found in the dry bed of the river Hekandue, a left tributary of river Jasačnaja in the Magadan district, Russia, near the settlement of Seymchan, in June 1967.
The main mass of 272.3 kg (600 lb) was found during a study made in June 1967 by the geologist FA Mednikov. The mass was a triangular thumb print meteorite lying among the stones of the river bed. A second specimen of 51 kg (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 given to the Academy of sciences of the USSR.
During a new expedition in 2004, Dmitri Kachalin recovered approx. 50 kg of new material. Remarkably, approximately 20% of the new specimens contained olivine crystals, revealing the silicate nature of the meteorite. The pallasitic structure had not yet been discovered in studies of small sections of the initial mass, composed only of metal.
Seymchan belongs to the main pallasite group, but it is considered unusual because of its high iridium content. Before the discovery of its pallasitic structure, it had been classified as IIE anomalous coarse octahedrite. Seymchan is considered to be a stable and rust-resistant pallasite.
