Seymchan Location 62° 54'N, 152° 26'E
Magadanskaya distrikt, Russia
Find: June 1967
Circumstances of the fall or discovery: The larger specimen has been found by the geologist F. A. Mednikov during a geological survey.
The meteorite hardly seen was lying among the stones of the brook-ebd.
The smaller specimen was found at a distance of 20 m from the first one by I. H. Markov with a mine detector in october 1967.
The main mass was turned to the Academy of Sciences of the USSR.
A small section of iron was analyzed by J.Wasson and it was determinated to be a member of chemical group IIE.
During a 2004 expedition additional masses were found. Many of them were found to contain silicates with a pallasitic texture.
So it was reclassificated to main group pallasite. And now Seymchan is an anomalous pallasite due to its high Ir content (van Niekerk et al. 2007)
Classification: Pallasite (Main group).
Seymchan is one of the most beautiful and stable meteorites without any doubt. Widmanstatten pattern of Seymchan meteorite is VERY GOOD.
So it was possible to make some clock faces from it and make wonderful watches.
