Possible iron meteorite

Iron meteorite, likely an ataxite or coarse octahedrite; composition mainly Fe–Ni alloy

AI-generated identification · may be incorrect

Dark brown-black, strongly metallic to submetallic luster, rounded melted exterior, and numerous shallow pits or regmaglypts. Typical hardness is about 4–5 Mohs; unusually high density (~7–8 g/cm³) and strong magnetism are expected, though the image alone cannot confirm these traits.

Physical properties

Dark brown-black, strongly metallic to submetallic luster, rounded melted exterior, and numerous shallow pits or regmaglypts. Typical hardness is about 4–5 Mohs; unusually high density (~7–8 g/cm³) and strong magnetism are expected, though the image alone cannot confirm these traits.

Formation & geological history

Likely formed in the metallic core of a differentiated asteroid, crystallizing billions of years ago before being liberated by an impact and surviving atmospheric entry. The pitted surface may represent ablation and regmaglypt formation.

Uses & applications

Primarily a collector specimen; polished slices can display Widmanstätten patterns and are used in jewelry, sculptures, and educational displays.

Geological facts

The appearance is consistent with a weathered iron meteorite, but terrestrial iron slag, industrial metal, or iron-rich rock can look similar. A nickel test and laboratory elemental analysis are required for authentication.

Field identification & locations

Check for strong attraction to a magnet, unusually high density, a thin fusion crust, and no obvious vesicular glassy texture; avoid destructive testing. Common finds include Argentina, Namibia, Sweden, Australia, and the United States.
