Metallic iron meteorite (probable)

Iron meteorite, typically kamacite–taenite (Fe–Ni alloy)

AI-generated identification · may be incorrect

Dark gray metallic surface with silvery reflections, dense appearance, and irregular pits or fusion-crust remnants; likely magnetic. Iron meteorites have Mohs hardness about 4–5, metallic luster, high specific gravity (~7–8), and no ordinary mineral cleavage.

Physical properties

Dark gray metallic surface with silvery reflections, dense appearance, and irregular pits or fusion-crust remnants; likely magnetic. Iron meteorites have Mohs hardness about 4–5, metallic luster, high specific gravity (~7–8), and no ordinary mineral cleavage.

Formation & geological history

Formed in the metallic cores of differentiated asteroids billions of years ago, then excavated by impacts and melted during atmospheric entry. The visible surface may show oxidation and weathering after landing.

Uses & applications

Primarily collected and studied; larger, stable pieces may be cut and polished for display or jewelry. Scientific value depends on confirmed extraterrestrial composition and classification.

Geological facts

The specimen’s rounded, dark, metallic-looking appearance is consistent with a meteorite, but slag, industrial metal, or magnetite can look similar. Nickel testing and laboratory analysis are required for confirmation.

Field identification & locations

Check for strong attraction to a magnet, unusually high density, a thin fusion crust, and a streak that is not reddish-brown; avoid scratching or acid testing. Common finds occur in dry deserts and Antarctica, while verified ordinary iron meteorites often sell for about $1–$20 per gram; unverified finds may be worth little.
