Seymchan Meteorite Cross-Section
Circa 4.5 billion years B.P.Sold for (Inc. bp): £8,450
A magnificent polished cross-section from the Seymchan pallasite meteorite, revealing the honeycomb-like structure characteristic of pallasites, with translucent olivine crystals embedded within iron-nickel crystals; accompanied by a custom-made display stand. 356 grams, 23.2 cm
Discovered in 1967, recovered from the bed of the river Hekandue in the Magadan District, Russia (62° 54’ N, 152° 26’ E).
The main mass of 272.3 kilograms was found during a survey in June 1967 by geologist F. A. Mednikov. The mass was a triangular-shaped thumb-printed meteorite lying among the stones of the brook bed. A second specimen of 51 kilograms was found with a mine detector at a distance of 20 meters from the first in October 1967 by I. H. Markov. During a new expedition in 2004, Dmitri Kachalin recovered about 50 kilograms of new material. Remarkably, about 20% of the new specimens were found to contain olivine crystals, and so revealed the silicate nature of the meteorite. The pallasitic structure was not previously discovered during studies on small metal-only sections of the original mass. The distortion of the Widmanstatten patterns is interpreted as shearing of the superheated meteorite as it broke up in the Earth's atmosphere. -
