Recent developments of methods and applications of computer simulation for crystal fractionation and cooling histories of minerals are given after reviewing computer simulation of crystal structures of mantle minerals. Simulations of the structures have been applied to diffusion phenoma of ions in minerals and to possible derivation of partition coefficients of trace elements during crystal fractionation. Cooling rates subsequent to crystallization of meteoritic minerals have been estimated by simulation of diffusion profiles in minerals by a computer.
