Likely iron meteorite fragment

Fe–Ni metallic meteorite, possibly an octahedrite (kamacite–taenite alloy)

AI-generated identification · may be incorrect

Dark, irregular, heavily textured metallic specimen; fresh iron meteorites are dense, magnetic, and typically have a metallic luster. Mohs hardness is about 4–5, with specific gravity commonly 7.3–7.8; the blue lighting obscures true color and surface details.

Physical properties

Dark, irregular, heavily textured metallic specimen; fresh iron meteorites are dense, magnetic, and typically have a metallic luster. Mohs hardness is about 4–5, with specific gravity commonly 7.3–7.8; the blue lighting obscures true color and surface details.

Formation & geological history

Formed in the metallic core of a differentiated asteroid roughly 4.5 billion years ago, then released by impact and surviving atmospheric entry. Sculpted or pitted surfaces may reflect ablation, weathering, or handling.

Uses & applications

Primarily a collector specimen; cut and etched pieces may display Widmanstätten patterns. It has little practical industrial use at specimen scale.

Geological facts

Identification cannot be confirmed visually from this image alone; terrestrial iron slag, magnetite, or weathered metal can look similar. A nickel test, strong magnet response, density measurement, and laboratory analysis are useful.

Field identification & locations

Common sources include Northwest Africa, Antarctica, and historically Campo del Cielo and Sikhote-Alin. Look for fusion crust, regmaglypts, unusual density, magnetism, and a non-rusty metallic interior; obtain certified provenance.
