| Outline of Final Research Achievements |
Nitrogen is a major element in the atmosphere and one of the very important elements for life. However, the budget ant behavior in the deep earth is unclear. In this research project, we synthesized mantle minerals using a multi anvil high-pressure apparatus and investigated concentrations of nitrogen. We found that the lower mantle can be an important nitrogen reservoir.
