Likely iron-rich rock or metallic mineral fragment

Uncertain; possibly limonite/goethite-rich material or weathered iron meteorite fragment

AI-generated identification · may be incorrect

Dark brown to black, dull-to-submetallic luster, irregular fracture, and apparently dense/granular texture. Hardness cannot be determined visually; a magnet test and streak test would help distinguish meteorite metal from terrestrial iron oxides.

Physical properties

Dark brown to black, dull-to-submetallic luster, irregular fracture, and apparently dense/granular texture. Hardness cannot be determined visually; a magnet test and streak test would help distinguish meteorite metal from terrestrial iron oxides.

Formation & geological history

May form through terrestrial oxidation of iron-bearing minerals, or less likely represent a weathered meteorite; the photograph alone cannot establish geological age or origin.

Uses & applications

Common iron-oxide material has little commercial value as an isolated fragment, though iron ores are industrially important. A confirmed meteorite could have collector interest.

Geological facts

The rough, earthy appearance lacks obvious visible metallic fusion crust or regmaglypts, so a meteorite identification is not supported from the image alone.

Field identification & locations

Test with a strong magnet, inspect the streak on unglazed ceramic, and check density; hematite gives a red-brown streak, magnetite a black streak and strong magnetism, while metallic meteorites usually show a gray streak and unusually high density. Common fragments are typically worth $1–$10; a verified meteorite may range from $50 to thousands depending on classification.
