TheChinga meteorite is aniron meteorite. It is structurally anataxite with very rarekamacitelamella. Themeteoric iron is a part of the lamellataenite.[2] The total chemical composition is 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus.[3]
Fragments of the meteorite were found in 1913 by gold diggers inTuva near theChinge River after which it is named. Eventually, Nikolay Chernevich, a mining engineer supervising the gold diggers, sent thirty pieces, the heaviest of which was 20.5 kilograms (45 lb), to theRussian Academy of Sciences inSaint Petersburg.[3] Later expeditions have retrieved about 250[citation needed] pieces with a total mass of 209.4 kilograms (462 lb).[1]
No impact structure was found.[3] 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 aglacier.[citation needed]
As of December 2012[update] pieces of the Chinga meteorite were on sale forUS$1 to 2/g.[4]
The Chinga meteorite was classified as anIVB meteorite (Subgroup "an") in 2000, but was reclassified as an Iron ungrouped (Iron-ung) in 2006.[1]
TheIron Man is a statue that was possibly made from a fragment of the Chinga meteorite.[5]
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.[5]
