Iron meteorite candidate

Fe–Ni metallic meteorite, possibly an ordinary octahedrite

AI-generated identification · may be incorrect

Rounded, weathered brown-gray metallic mass with numerous bright reflective grains; likely very dense, magnetic, and metallic-lustered. Iron meteorites typically have Mohs hardness about 4–5 and specific gravity around 7–8; the image alone cannot confirm composition or Widmanstätten structure.

Physical properties

Rounded, weathered brown-gray metallic mass with numerous bright reflective grains; likely very dense, magnetic, and metallic-lustered. Iron meteorites typically have Mohs hardness about 4–5 and specific gravity around 7–8; the image alone cannot confirm composition or Widmanstätten structure.

Formation & geological history

Formed in the metallic core of a differentiated asteroid, likely more than 4.5 billion years ago, then delivered to Earth as a meteorite. Surface browning may represent terrestrial iron-oxide weathering.

Uses & applications

Primarily a scientific and collector specimen; cut and etched pieces are used for jewelry and displaying Widmanstätten patterns. Verified specimens can be valuable.

Geological facts

Visual identification is uncertain because metallic slag, pyrite-rich rock, and other iron-bearing materials can look similar. A strong magnet, unusually high density, and nickel confirmation support meteoritic origin.

Field identification & locations

Check for fusion crust, regmaglypts, lack of vesicles, strong magnetism, and a streak that is not bright red-brown; avoid destructive tests before professional authentication. Common finds occur in arid regions and Antarctica.
