Weathered meteorite.

Space weathering is the type of weathering that occurs to any object exposed to the harsh environment of outer space. Bodies without atmospheres (including the Moon, Mercury, the asteroids, comets, and most of the moons of other planets) take on many weathering processes: bombardment by different sizes of meteorites and micrometeorites.Gebel Kamil is an iron meteorite that was found in Egypt back in 2009.

Meteorite weathering is the terrestrial alteration of a meteorite. Most meteorites date from the oldest times in the Solar System and are by far the oldest material available on our planet. Despite their age, they are vulnerable to the terrestrial environment. Water, chlorine and oxygen attack meteorites as soon as they reach the ground. Analysis of Antarctic salt deposits on a heavily weathered meteorite (LEW 85320) by μL 2 MS did not show the presence of terrestrial PAHs within detection limits, which suggests an upper limit for terrestrial contamination of ALH84001 of 1%.
