| Outline of Final Research Achievements |
Focusing on xenon as lost elements during planet formation and evolution, studies were conducted based on high-pressure high-temperature experiments about the possibility that the lost xenon is fixed in the deep part of the earth. In this study, it has been investigated whether xenon could be fixed to minerals and metals in the deep Earth and natural clathrates. No reactivities with xenon has been found in mantle mineral, metals and silica clathrate even under lower mantle conditions. The lost xenon is an issue to be solved other than the reaction with the mineral.

| Academic Significance and Societal Importance of the Research Achievements |
現在の大気に含まれるキセノンが想定より優位に少ない問題は1980年代に提起されたが、いまだ解決を見ていない。この問題に対しこれまで多くの可能性が提案されており、本研究の成果は、この問題は鉱物・金属との反応以外で解決されることを示唆している。また、キセノンは稀少な資源物質であり、失われたキセノンが地球深部などに存在する可能性を検証することは、その稀少資源の埋蔵量を検証することにつながる。今回の研究によってキセノンの新たな資源は地球深部の鉱物や天然のクラスレートには期待できないことが明らかとなった。
