Possible iron meteorite fragment

Likely iron–nickel metal (kamacite and taenite); identification is uncertain from the photo alone

AI-generated identification · may be incorrect

Dark brown-gray, rounded, with a metallic reflective patch and irregular surface. Hardness and crystal structure cannot be determined visually; iron meteorites are dense and typically show metallic luster when freshly exposed.

Physical properties

Dark brown-gray, rounded, with a metallic reflective patch and irregular surface. Hardness and crystal structure cannot be determined visually; iron meteorites are dense and typically show metallic luster when freshly exposed.

Formation & geological history

If meteoritic, it formed in the core of an ancient differentiated asteroid and reached Earth as a meteorite; its age would be billions of years. Similar-looking terrestrial iron-rich rocks or industrial slag are common alternatives.

Uses & applications

Meteorite specimens are collected and studied; iron meteorites may be cut and polished for display or jewelry.

Geological facts

A magnet test can support an iron-rich composition but does not prove a meteorite. A nickel test and laboratory examination are more reliable.

Field identification & locations

Look for unusually high density, magnetism, and a fusion crust; confirm with a qualified meteorite specialist, since the photo is insufficient for a firm identification. Iron meteorites are found worldwide, often in arid regions.
