While Q gases, the planetary noble gases enriched in the heavy noble gases(Ar, Kr, and Xe), from chondritic meteorites have been well studied, the carrier of Q gases, phase Q, is yet to be identified. In this study, we have conducted the quantitative molecular characterization of Q-rich and Q-poor carbonaceous materials, which were physically or chemically separated from meteorite, by X-ray absorption near edge structure(XANES) spectroscopy using the scanning transmission X-ray microscope(STXM). It is suggested that some sp^3 carbon may be related to the release of Q gases and/ or phase Q.
