What is "iron meteorite"

n. (context geology English) Any of a class of meteorite that is composed mostly of iron and nickel alloys

Iron meteorites are meteorites that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Iron meteorites originate from planetary cores of planetesimals.

The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, before the development of smelting that signaled the beginning of the iron age.
