Meteoric iron - Wikipedia
Meteoric iron, sometimes meteoritic iron, [1] is a native metal and early-universe protoplanetary-disk remnant found in meteorites and made from the elements iron and nickel, mainly in the form of the mineral phases kamacite and taenite.
Iron meteorite - Wikipedia
Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite.
Iron Meteorites: Composition, Age, and Origin | Oxford Research ...
Iron meteorites are thought to be samples of metallic cores and pools that formed in diverse small planetary bodies. Their great diversity offers remarkable insights into the formation of asteroids and the early history of the solar system.
Iron Meteorites: Origin, Classification, Pictures - Geology.com
Iron meteorites are very dense - much heavier than almost all terrestrial rocks - and will easily adhere to a strong magnet. Iron meteorites also contain a relatively high percentage of nickel - a metal very rarely found on Earth - and they display a unique feature that is never seen in terrestrial material.

Iron Meteorite: A superb 1,363-gram complete iron meteorite from the Sikhote-Alin meteorite shower which occurred in a remote part of eastern Siberia in the winter of 1947. This fine specimen is described as a complete individual, as it flew through the atmosphere in one piece, without fragmenting.
Iron meteorite | Meteorite Classification, Composition, Structure ...
Iron meteorite, any meteorite consisting mainly of iron, usually combined with small amounts of nickel. When such meteorites, often called irons, fall through the atmosphere, they may develop a thin, black crust of iron oxide that quickly weathers to rust.

2024年10月21日 · Iron meteorites are pieces of denser metal that segregated from the less-dense silicates when their parent bodies were at least partially melted.
Iron meteorites – Buseck Center for Meteorite Studies
Iron meteorites. Most iron meteorites likely originated in the cores of large asteroids, and are composed almost entirely of nickel-iron alloy, which is also a primary component of the Earth's core. Even though iron meteorites account for less than 5% of observed falls, they are more easily recognized than other types of meteorites.
Heavy iron isotope composition of iron meteorites explained by …
2020年8月3日 · Recent iron isotope analyses of iron meteorites found their 57 Fe/ 54 Fe ratios to be heavier than chondritic by approximately 0.1 to 0.2 per mil for most meteorites, indicating that a common...
