| Abstract |
The interstellar dusts are micron-sized solid particles whose model consists of silicate minerals, ice, and organic molecules. Through accretion of gas and dusts in interstellar cloud, the Solar System and its primitive materials (asteroids, meteorites, and comets) were formed 4.5 Gyr ago. To date, the studies of organic analyses of meteorites have revealed significant variations in molecular and isotopic compositions according to the meteorite chemical groups and petrologic types. This indicates that the original composition of common precursor of organics has been modified with the progress of parent body aqueous/thermal processes reflected by meteorite mineral compositions. Thus, co-evolution of minerals, water (ice), and organics must have been the important chemical history for the formation of the Solar System. |
