Solid State Chemistry and Physics of Minerals

这个项目的目标是了解矿物晶格过程，这些过程导致矿物的弹性、热力学和运输性质。对镁橄榄岩的比热进行了计算，计算结果与量热法测得的值吻合较好。对镁橄榄岩的计算现在将扩展到包括热膨胀、可压缩性以及弹性常数与压力和温度的关系。类似的研究也将在铁钛矿粉和钙钛矿粉上进行。这些矿物是地幔中的主要相态，了解它们的性质将有助于解释地震数据。

The goal of this project is to understand mineral lattice processes that give rise to the elastic, thermodynamic and transport properties of minerals. Calculations have been completed for specific heat of forsterite which agree well with values obtained by calorimetry. The calculations for forsterite will now be extended to include thermal expansion, compressibility , and the pressure and temperature dependence of the elastic constants. A similar study will be carried out on fayalite and perovskite. These mineral are major phases in the earth's mantle and knowledge of their properties will facilitate interpretation of seismic data.
