中文摘要
主要研究人员将在高温下研究矿物行为。 压力和温度,并试图将晶体的变化 在这样的条件下, 热力学性质他们将收集X射线和拉曼 并根据朗道理论对数据进行了分析 理论这项工作应有助于更好地了解 地壳和上地幔中物质的行为。
英文摘要
The principal investigators will study mineral behavior at high pressures and temperatures and attempt to relate changes in crystal structure under such conditions to changes in physical and thermodynamic properties. They will collect X-ray and Raman spectroscopic data in-situ, and analyze the data in light of Landau theory. This work should lead to a better understanding of the behavior of materials in the Earth's crust and upper mantle.
