Outline of Final Research Achievements

We determined, through laboratory experiments, evaporation and vapor-growth rates of forsterite (Mg2SiO4) in the low-pressure H2-H2O system, crystallization rates of amorphous silicates with forsterite and enstatite stoichiometry, oxygen isotopic exchange rates between the amorphous silicates and low-pressure water vapor. The results indicates that chemistry and mineralogy of Mg-silicates should depend on the radial distance from the proto Sun in the early Solar System.

Academic Significance and Societal Importance of the Research Achievements

太陽系の惑星には化学的多様性がある．小惑星イトカワと小惑星リュウグウも化学組成が異なると考えられている．これらの化学的多様性は太陽系初期に固体，気体間の化学反応でつくられた可能性が高い．岩石天体の主成分マグネシウム，ケイ素の分別をつくる反応について実験をおこない，初期太陽系で固体の元素・同位体組成や構造の分布に違いができることがわかった．本成果は太陽系初期の惑星材料の姿の理解に貢献できると考える．
