earthstory:Meteorite magnetism reveals secrets of early solar systemPallasites are the most attractive meteorites, with their green to brown crystals of olivine embedded in a shiny matrix of metallic iron and nickel. Long thought to be the core mantle boundaries of ancient planetismals (the building blocks of our solar system), they may be due instead to collisions between them but the issue is still in doubt. They are thought to be the remnants of the first bodies in the solar system, many of which amalgamated together to form the planets.
