Heterogeneous growth of meteorites and planets, especially the earth and moonIt is pointed out that enough information remains in meteorites to show that the solar nebula was chemically inhomogeneous, and that it did not develop under physical and chemical equilibrium. It is found that the earth is not in chemical equilibrium, and that it still retains vestiges of its heterogeneous growth in spite of prolonged convection and volcanism. The present investigation has the aim to unify simple ideas into a comprehensive, complex scheme for heterogeneous growth of the planets and parent bodies of meteorites. A scheme is considered for the conversion of dust and gas in the solar nebula into the present population of bodies. Attention is given to possible processes for the growth and development of planetesimals from dust via clouds, the major episodes in the development of the solar system, the relation of meteorites to a solar nebula with monotonic variation of temperature and oxidation state, the significance of meteorite properties, the composition of the inner planets, and the development of the earth.
