Iron meteorite fragment (probable)

Fe–Ni metallic meteorite, likely an octahedrite

AI-generated identification · may be incorrect

Dark brown-black, metallic to earthy luster, irregular fractured surface, and high density; commonly contains kamacite and taenite. Mohs hardness is approximately 4–5, with no obvious terrestrial crystal cleavage; identification requires testing for nickel and a fusion crust.

Physical properties

Formation & geological history

Formed in the metallic core of a differentiated asteroid and crystallized billions of years ago, typically 4.5 billion years old; reached Earth after atmospheric entry. The image alone cannot distinguish it confidently from terrestrial slag or iron-rich rock.

Uses & applications

Authentic meteorites are collector specimens and may be used for scientific study; they have no major industrial use. Small verified fragments are commonly sold to collectors.

Geological facts

Likely indicators include unusually high density, attraction to a magnet, rounded atmospheric-flow surfaces, and a thin dark fusion crust; a fresh broken face may reveal metal. Rusting alone does not prove meteorite origin.

Field identification & locations

Common iron meteorites include Canyon Diablo and Sikhote-Alin, but provenance and laboratory confirmation are essential; nickel testing and examination for Widmanstätten patterns are useful. Slag often has bubbles, glassy areas, or irregular oxidation.
