Iron meteorite (probable)

Fe–Ni metallic meteorite, commonly kamacite–taenite

AI-generated identification · may be incorrect

Dark gray to black, strongly metallic luster, irregular fusion-crust-like surface, and high density; Mohs hardness about 4–5. The image is insufficient to confirm crystal structure, nickel content, or magnetic response.

Physical properties

Dark gray to black, strongly metallic luster, irregular fusion-crust-like surface, and high density; Mohs hardness about 4–5. The image is insufficient to confirm crystal structure, nickel content, or magnetic response.

Formation & geological history

Formed in the metallic cores of differentiated asteroids and released by impacts; most meteorites formed roughly 4.5 billion years ago. The dark exterior may be atmospheric fusion crust, but terrestrial slag or iron-rich rock remains possible.

Uses & applications

Primarily collected and studied; cut and etched specimens display Widmanstätten patterns and may be used in jewelry or educational displays.

Geological facts

Reliable identification requires a strong magnet, density measurement, nickel testing, and laboratory analysis; meteorites commonly show a thin black/brown fusion crust and regmaglypts.

Field identification & locations

Look for unusually high density, magnetism, rounded edges, and a thin melted crust; avoid relying on appearance alone because industrial slag can look similar. Common finds occur in dry deserts and Antarctica.
