The Chinga meteorite is an iron meteorite. It is structurally an ataxite with very rare kamacite lamella. The meteoric iron is a part of the lamella taenite. The total chemical composition is 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus.{{cite journal|last=Антуфьева|first=Надя|date=November 17, 2012|script-title=ru:Загадка тувинского метеорита Чинге: к столетию открытия посланца Космоса|journal=Центр Азии|volume=2012|issue=45|url=http://www.centerasia.ru/issue/2012/45/4435-zagadka-tuvinskogo-meteorita-chinge-k.html|language=ru}}

History

Fragments of the meteorite were found in 1913 by gold diggers in Tuva near the Chinge River after which it is named. Eventually, Nikolay Chernevich, a mining engineer supervising the gold diggers, sent thirty pieces, the heaviest of which was {{convert|20.5|kg|lb}}, to the Russian Academy of Sciences in Saint Petersburg. Later expeditions have retrieved about 250{{citation needed|date=December 2012}} pieces with a total mass of {{convert|209.4|kg}}.{{cite web|title=Meteoritical Bulletin Database|url=http://www.lpi.usra.edu/meteor/metbull.php?code=5353|publisher=Meteoritical Society|access-date=19 December 2012}}

No impact structure was found. Studies from the fluvial deposits in which the meteorites was found estimate that it fell about 10,000 to 20,000 years ago. It burst during passage through the atmosphere, the pieces impacting on a glacier.{{citation needed|date=December 2012}}

Classification

The Chinga meteorite was classified as an IVB meteorite (Subgroup "an") in 2000, but was reclassified as an Iron ungrouped (Iron-ung) in 2006.

In culture

The Iron Man is a statue that was possibly made from a fragment of the Chinga meteorite.{{cite journal|last=BUCHNER|first=Elmar|author2=SCHMIEDER, Martin |author3=KURAT, Gero |author4=BRANDSTÄTTER, Franz |author5=KRAMAR, Utz |author6=NTAFLOS, Theo |author7= KRÖCHERT, Jörg |title=Buddha from space-An ancient object of art made of a Chinga iron meteorite fragment*|journal=Meteoritics & Planetary Science|date=1 September 2012|volume=47|issue=9|pages=1491–1501|doi=10.1111/j.1945-5100.2012.01409.x|bibcode=2012M&PS...47.1491B|doi-access=free}}

Researchers say the 1,000-year-old object with a swastika on its stomach is made from a rare form of iron with a high content of nickel.
