Possible iron-rich meteorite fragment

Unclassified stony-iron or iron meteorite; exact identification requires testing

AI-generated identification · may be incorrect

Irregular dark metallic-looking specimen with rusty brown/yellow weathering; likely high specific gravity and magnetic response. Apparent texture is obscured by the low-resolution image, so hardness, crystal structure, and cleavage cannot be reliably determined.

Physical properties

Irregular dark metallic-looking specimen with rusty brown/yellow weathering; likely high specific gravity and magnetic response. Apparent texture is obscured by the low-resolution image, so hardness, crystal structure, and cleavage cannot be reliably determined.

Formation & geological history

If meteoritic, it formed in a differentiated asteroid and later survived atmospheric entry; terrestrial weathering produces iron oxides. A terrestrial iron-rich rock or slag is also possible without a density, magnetism, and nickel test.

Uses & applications

Primarily a collector specimen; verified meteorites may have scientific and commercial value, while terrestrial ironstone has limited decorative or industrial use.

Geological facts

A fusion crust, regmaglypts, metallic interior, and nickel presence support meteorite identification; rusty coloration alone is not diagnostic.

Field identification & locations

Check for strong magnetism, unusually high density, a thin dark fusion crust, and nickel using laboratory analysis; avoid cutting until tested. Common meteorite finds occur in deserts and Antarctica.
