The principal investigator will study the partitioning of important radiogenic and trace elements between mineral and melt under mantle conditions. Using the laser heated diamond cell, experiments will be conducted at pressures up to 100 GPa and temperatures up to 5000 K. The proposed experiments will be the first done under the appropriate high pressure and temperature conditions to provide constraints on lower mantle geochemistry.

首席研究员将研究地幔条件下重要的放射性成因元素和微量元素在矿物和熔体之间的分配。使用激光加热的钻石池，将在高达100 Gpa和高达5000 K的温度下进行实验。拟议的实验将首次在适当的高压和温度条件下进行，以限制下地幔的地球化学。
