Likely iron meteorite fragment

Iron–nickel meteorite, primarily kamacite and taenite (Fe–Ni alloy)

AI-generated identification · may be incorrect

Dark brown-black, metallic to weathered luster, dense and irregularly pointed; typical hardness is about 4–5 Mohs, with no visible cleavage. The image is insufficient to confirm internal structure or magnetic response.

Physical properties

Dark brown-black, metallic to weathered luster, dense and irregularly pointed; typical hardness is about 4–5 Mohs, with no visible cleavage. The image is insufficient to confirm internal structure or magnetic response.

Formation & geological history

Formed in the metallic cores of differentiated asteroids, likely billions of years ago, then delivered to Earth by impact fragmentation; the rusty surface reflects terrestrial weathering.

Uses & applications

Primarily a collector specimen, educational object, or display piece; confirmed iron meteorites can be cut, polished, and etched to reveal Widmanstätten patterns.

Geological facts

A strong magnet, unusually high density, and a nickel test support identification, but industrial iron slag or metal debris can look similar. A fresh cut and acid etch may reveal crystalline kamacite–taenite bands.

Field identification & locations

Commonly found as isolated dark, heavy fragments in deserts, Antarctica, and some cultivated areas; look for regmaglypts, a fusion crust, and lack of vesicles. Professional testing is needed for authentication.
