Likely iron-rich meteorite or weathered sulfide-bearing rock

Unconfirmed; possible ordinary chondrite (stony meteorite) or iron-oxide/sulfide-bearing terrestrial rock

AI-generated identification · may be incorrect

Dark gray-brown, irregular, granular specimen with rusty orange weathering and scattered metallic-looking grains. Hardness is likely about 5–6, with submetallic to dull luster; magnetic response and a fresh cut or streak test would be important, but no crystal structure is diagnostic from the image.

Physical properties

Hardness is likely about 5–6, with submetallic to dull luster; magnetic response and a fresh cut or streak test would be important, but no crystal structure is diagnostic from the image.

Formation & geological history

If meteoritic, it formed in an asteroid and may be billions of years old, later acquiring a fusion crust and terrestrial oxidation. If terrestrial, likely a weathered basalt, ironstone, or sulfide-bearing metamorphic rock.

Uses & applications

Meteorites are mainly collector specimens and research materials; terrestrial equivalents may be used as aggregate or collected for appearance.

Geological facts

The apparent rusty matrix and dark exterior are compatible with oxidation, but appearance alone cannot confirm a meteorite. A strong magnet, unusually high density, lack of vesicles, and a thin fusion crust would support meteoritic origin.

Field identification & locations

Check for magnetism, density, a continuous fusion crust, and nickel by laboratory analysis; avoid destructive acid tests. Common terrestrial look-alikes are found worldwide, while confirmed meteorites require microscopy and chemical testing.
