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 …

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 …

More than 95% of all meteorites contain iron-nickel (FeNi) metal. As a consequence, meteorites have concentrations of nickel that are much greater than that of nearly any terrestrial rock. …

There are three main groups of meteorite: iron meteorites, stony-iron meteorites and stony meteorites. They differ in their amount of iron-nickel metal they contain and what they reveal …

Almost all meteorites contain extraterrestrial nickel and iron, and those that contain no iron at all are so rare that when we are asked for help and advice on identifying possible space rocks, …

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 - …

When asteroidal cores were exposed to the cold and vacuum of space as the result of cosmic collisions, the molten metal they comprised cooled over millions of years, resulting in the …

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 …

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 …

Most "iron" meteorites are iron-nickel alloy with a few scattered inclusions of sulfide minerals. The alloys are 5 to 12 percent nickel, with traces of cobalt, chromium, gold, platinum, iridium, …
