The bulk of meteoric iron consists of taenite and kamacite.Taenite is a face-centered cubic and kamacite a body-centered cubic iron-nickel alloy.. Meteoric iron can be distinguished from telluric iron by its microstructure and perhaps by its chemical composition also, since meteoritic iron contains more nickel and less carbon.
The Inuit used the Cape York meteorite for a much longer time. Iron meteorites themselves were sometimes used unaltered as collectibles or even religious symbols (e.g. Clackamas worshiping the Willamette meteorite). [15] Today iron meteorites are prized collectibles for academic institutions and individuals.

This would be explained by a recovery bias; laypeople are more likely to notice and recover solid masses of metal than most other meteorite types. The abundance of iron meteorites relative to total Antarctic finds is 0.4%. [23] [24] Stony-iron meteorites constitute the remaining 1%. They are a mixture of iron-nickel metal and silicate minerals.
Meteoric iron – a native metal found in meteorites and a mixture of different mineral phases. Compare telluric iron. Meteorite Observation and Recovery Program – a scientific program that was centered in Canada. Meteoriticist – a scientist working on meteorites, meteors, and meteoroids.
Early Iron Age ornaments unearthed in Poland have been found to contain iron from meteorites, suggesting the ancient inhabitants of the region were adept at working the metal much earlier than ...
Stony–iron meteorites have always been divided into pallasites (which are now known to comprise several distinct groups) and mesosiderites (a textural term that is also synonymous with the name of a modern group). Below is a representation of how the meteorite groups fit into the more traditional classification hierarchy: [1]
The term Gibeon encompasses the total extent of meteoritic material fallen from the sky during this fall. This material is classified as iron meteorite belonging to the chemical group IVA. [1] Gibeon meteorites are composed of an iron-nickel alloy containing significant amounts of cobalt and phosphorus.
