Possible iron-rich meteorite fragment

Undetermined; possibly an iron meteorite or stony-iron meteorite

AI-generated identification · may be incorrect

Small, irregular black-brown, metallic-looking fragment with a rough surface. Apparent hardness is likely above 5 Mohs; magnetic response, streak, density, and fusion crust cannot be determined from the image.

Physical properties

Small, irregular black-brown, metallic-looking fragment with a rough surface. Apparent hardness is likely above 5 Mohs; magnetic response, streak, density, and fusion crust cannot be determined from the image.

Formation & geological history

If extraterrestrial, it formed in a differentiated asteroid and may be billions of years old, later acquiring a dark fusion crust during atmospheric entry. Earth rocks, industrial slag, and iron-rich basalt can look similar.

Uses & applications

Meteorites are valued as scientific and collector specimens; confirmed examples may sell for substantially more than ordinary terrestrial rock.

Geological facts

The image alone cannot confirm a meteorite: dark slag and weathered terrestrial iron minerals are common look-alikes. A real meteorite typically has high density, strong magnetism if iron-bearing, and a thin fusion crust, but usually lacks obvious vesicles.

Field identification & locations

Check whether it attracts a strong magnet, leaves no black streak on unglazed ceramic, feels unusually dense, and shows metal flecks; professional testing should include nickel analysis and petrographic examination. Do not cut or clean it aggressively.
