Metallic iron meteorite fragments (probable)

Iron meteorite, chiefly kamacite (α-(Fe,Ni)) with possible taenite

AI-generated identification · may be incorrect

Irregular dark gray, strongly metallic pieces with silvery reflective surfaces; likely very dense and magnetic. Mohs hardness about 4–5; metallic luster, cubic body-centered iron-nickel structure, and no obvious cleavage. The image alone cannot confirm meteorite identity; industrial slag is a serious alternative.

Physical properties

Formation & geological history

Iron meteorites formed from molten metallic cores of differentiated asteroids and crystallized billions of years ago, commonly about 4.5 billion years old. They reached Earth as meteoroids and fragmented on impact or during handling.

Uses & applications

Authentic specimens are used for scientific study, education, and collecting; cut and etched pieces may display Widmanstätten patterns. Estimated value is $1–$10/g for common verified iron meteorites, higher for rare named falls.

Geological facts

A polished, acid-etched surface may reveal crosshatched Widmanstätten figures, while nickel is typically present. Metallic slag often has vesicles, flow textures, glassy surfaces, or rounded melt shapes and is frequently mistaken for meteorite.

Field identification & locations

Test with a strong magnet, inspect for bubbles and glassy areas, and check density; confirm with nickel testing, microscopy, and laboratory elemental analysis. Common sources include finds in deserts and Antarctica; unverified material has little market value.
