| 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.
