The reactivity of xenon with terrestrial oxides was investigated by in situ synchrotron x-ray diffraction. At high temperature (T > 500 kelvin), some silicon was reduced, and the pressure stability of quartz was expanded, attesting to the substitution of some xenon for silicon. When the quartz was quenched, xenon diffused out and only a few weight percent remained trapped in samples. These results show that xenon can be covalently bonded to oxygen in quartz in the lower continental crust, providing an answer to the missing xenon problem; synthesis paths of rare gas compounds are also opened.
通过原位同步加速器X射线衍射研究了氙与地球氧化物的反应活性。在高温（T>500开尔文）下，一些硅被还原，石英的压力稳定性得到扩展，这证明了部分氙取代了硅。当石英被淬火时，氙扩散出来，只有少数重量百分比的氙被困在样品中。这些结果表明，氙可以在下部大陆地壳中与石英中的氧共价键合，这为氙缺失问题提供了答案；同时也开辟了稀有气体化合物的合成途径。
