Meteorite weathering
Terrestrial alteration of a meteorite / From Wikipedia, the free encyclopedia
Not to be confused with Space weathering.
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.
