For example, some achondrites have a few percent carbon. Some chondrites have veins of water soluble salts as if deposited by movement of water as in hydrothermal processes that occured on Earth. Some readers from the mining industry are probably asking what mineral distributions exist in meteorites. Below are the properties of four different asteroids based on four meteorites. There is also a major caveat when extrapolating from meteorites to asteroids.
Many meteors break apart, disperse or burn up in Earth's atmosphere.
Volatile rich meteors usually explode due to heating during the fiery atmospheric entry. Soft and crumbly chondrites would be expected to break apart often, even if they were volatile poor. Irons and stony irons punch thru the most. Meteorites found on top of the snow in Antarctica are also classified as finds. Some finds come from rooftops and the like.
