Meteorites on Ice

Meteorites have great scientific value because most of them are fragments of asteroids which are themselves remnants of larger bodies that formed in the solar system at the time the planets accreted from planetesimals in the protoplanetary disk that formed around the Sun at the time of its formation about 4.6 x 10 years ago. Therefore, meteorites are our principal source of information about the origin of Earth and of the other planets of the solar system. [Pg.635]

Meteorites that fall in temperate and tropical climatic zones of the continents are rapidly altered by their exposure to water and to the terrestrial atmosphere. Therefore, only those meteorites that are observed to fall and which are immediately collected and preserved in specialized laboratories are suitable for study. The meteorites that have been entombed in the East Antarctic ice sheet are not falls strictly speaking, but they have been protected [Pg.635]
