| Research Abstract |
In order to examine the chemical composition of organic materials derived by meteoirte- and comet-impacts on the early Earth, shock experiments of artificial meteorite (organic materials + serpentinite powder), artificial comet (organic materials + water + olivine powder), and the Murchison meteorite were performed. Results of shock experiments for amino acids are oligomerization of amino acids up to trimers occurred in the pressure range of 15 GPa to 20 GPa. Results of shock exp eriments for amino acids are carboxylic acids were produced from other organic materials in the Murchison meteorite by impact shock.
