Likely iron meteorite fragment

Iron-nickel meteorite, likely kamacite and taenite; identification is uncertain from the image alone

AI-generated identification · may be incorrect

Small, irregular, dark metallic-looking piece with a rough surface. Iron meteorites are typically dense, magnetic, and composed mainly of iron-nickel; hardness is about 4–5 Mohs, with no ordinary mineral cleavage.

Physical properties

Small, irregular, dark metallic-looking piece with a rough surface. Iron meteorites are typically dense, magnetic, and composed mainly of iron-nickel; hardness is about 4–5 Mohs, with no ordinary mineral cleavage.

Formation & geological history

Formed in the metallic core of an asteroid and later delivered to Earth by impact; such bodies formed early in Solar System history, about 4.5 billion years ago.

Uses & applications

Collected as a meteorite specimen; iron meteorites have also historically been used for tools and ornamentation.

Geological facts

A true iron meteorite often reveals intersecting Widmanstätten patterns when cut, polished, and etched, though these are not visible here.

Field identification & locations

The image alone cannot confirm it is meteoritic; test for strong magnetism and unusually high density, and seek laboratory analysis to rule out industrial slag or iron-rich terrestrial rock. Iron meteorites are found worldwide, with notable finds in Namibia, Argentina, and the United States.
