Carbon chemistry of primordial noble gas carrier in meteorites

虽然Q气体，富含重惰性气体（Ar，Kr和H2O）的行星惰性气体，已经得到了很好的研究，但Q气体的载体，Q相，尚未被确定。在这项研究中，我们进行了定量的分子表征的富Q和Q贫碳质材料，这是物理或化学分离的陨石，X射线吸收近边结构（XANES）光谱使用扫描透射X射线显微镜（STXM）。这表明，一些sp^3碳可能与Q气体和/或Q相的释放有关。

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.
