- Abstract
Vaporization and condensation are the most important processes in the early solar nebula; both condensates and residues of vaporization may be related to the origin of meteoritic materials such as Ca-Al-rich inclusions, chondrules, their rims, and chondrite matrices. Although many thermodynamic calculations have been performed on the condensation of gases with compositions similar to that of the solar system1-5, few condensation experiments have been carried out. We have vaporized olivine crystals and succeeded in condensing coarse-grained olivine, pyroxene, a silica mineral and metallic iron from a gas composed of olivine components and hydrogen at 1,200-500 °C at low pressures. Thus the most abundant phases in meteorites condense in the laboratory under conditions similar to those of the solar nebula.
