Possible weathered metallic meteorite fragment

Unclassified iron-rich meteorite; exact classification requires laboratory testing

AI-generated identification · may be incorrect

Irregular brown-black, rusted surface with possible metallic interior; likely dense and magnetic, with metallic luster on fresh faces. Iron meteorites are mainly kamacite and taenite, Mohs hardness about 4–5, with no cleavage.

Physical properties

Irregular brown-black, rusted surface with possible metallic interior; likely dense and magnetic, with metallic luster on fresh faces. Iron meteorites are mainly kamacite and taenite, Mohs hardness about 4–5, with no cleavage.

Formation & geological history

Could be an oxidized meteorite formed in a differentiated asteroid’s metallic core, typically billions of years old; terrestrial iron-rich slag or ordinary iron-bearing rock is also possible from the image alone.

Uses & applications

Meteorites are valued primarily by collectors and researchers; iron meteorites are studied for planetary differentiation and may be cut, polished, and etched to reveal Widmanstätten patterns.

Geological facts

A magnet, high density, rounded fusion crust, and lack of vesicles support meteoritic identification, but rust alone is not diagnostic. A nickel test and laboratory elemental analysis are needed.

Field identification & locations

Common possibilities include iron meteorites such as Canyon Diablo, but terrestrial iron slag is far more common. Check for strong magnetism, a thin fusion crust, regmaglypts, and absence of bubbly texture; avoid destructive testing without expert advice.
