Metallic meteorite fragment (probable stony-iron or iron meteorite)

Undetermined meteoritic Fe–Ni alloy with silicate minerals

AI-generated identification · may be incorrect

Irregular dark gray-brown fragment with a metallic-looking surface and possible fusion-crust remnant; exact hardness, density, magnetism, and crystal structure cannot be established from the photograph. The cavity may reflect weathering or a broken interior.

Physical properties

Irregular dark gray-brown fragment with a metallic-looking surface and possible fusion-crust remnant; exact hardness, density, magnetism, and crystal structure cannot be established from the photograph. The cavity may reflect weathering or a broken interior.

Formation & geological history

Likely formed in an asteroid’s differentiated interior and crystallized billions of years ago, then reached Earth after atmospheric entry. Terrestrial slag or industrial metal remains a possible visual look-alike requiring testing.

Uses & applications

Meteorites are primarily valued for scientific study and collecting; iron-rich specimens may be cut, polished, and displayed. No ordinary construction use is applicable.

Geological facts

A true iron meteorite commonly contains kamacite and taenite and may reveal a Widmanstätten pattern after etching; stony-iron types contain visible silicate crystals.

Field identification & locations

Test with a strong magnet, measure density, inspect for a thin fusion crust, and seek nickel testing or professional classification; ordinary rocks rarely combine strong magnetism with unusually high density. Common finds occur in deserts and Antarctica.
