Dynamics and Chemistry of Planet Construction Simulations of planetary accretion suggest that the inner planets formed from planetesimals derived from a range of distances from the Sun. Simulations from O’Brien et al. (2006) http://www.psrd.hawaii.edu/Mar10/PlanetConstruction.html Dynamics and Chemistry of Planet Construction The compositions of simulated planets are reasonable matches for Mars, but lower in Mg/Si than Earth. Simulation for 500,000 years after formation of the solar nebula. Nevertheless, this is the first attempt to integrate accretion dynamics with solar nebula chemistry. Future work will build on this study. http://www.psrd.hawaii.edu/Mar10/PlanetConstruction.html
