Possible iron meteorite

Iron–nickel meteorite, commonly kamacite-taenite (Fe-Ni alloy)

AI-generated identification · may be incorrect

Dark brown-black, metallic to dull luster, dense and rounded with apparent fusion-crust weathering; Mohs hardness about 4–5.5. A magnet should attract it strongly; polished metal may reveal a Widmanstätten pattern after etching.

Physical properties

Dark brown-black, metallic to dull luster, dense and rounded with apparent fusion-crust weathering; Mohs hardness about 4–5.5. A magnet should attract it strongly; polished metal may reveal a Widmanstätten pattern after etching.

Formation & geological history

Formed in the metallic core of a differentiated asteroid and crystallized billions of years ago, typically 4.5–4.6 billion years old. Its dark exterior may be fusion crust or terrestrial oxidation (iron-oxide scale).

Uses & applications

Primarily a collectible and scientific specimen; cut and polished meteorites are used in jewelry and displays. Value depends heavily on verified extraterrestrial origin, classification, mass, and aesthetics.

Geological facts

The shape and dark, dense appearance are compatible with an iron meteorite, but ordinary terrestrial iron-rich rock, slag, or weathered metal can look similar. Visual inspection alone cannot authenticate it.

Field identification & locations

Check for strong magnetism, unusually high density, no vesicles, and a thin dark fusion crust; professional testing should include nickel analysis and petrographic examination. Common finds occur in arid regions and Antarctica.
