Equation of State Measurements on Molten Silicates

PI提出了一个实验和理论方案来确定高压下硅酸盐液体的状态方程，以定量地了解深部地幔源岩浆的形成。提出了液体激波实验，得到了硅酸盐熔体中重要组分SiO2、MgO、CaO、Al2O3和FeO的偏摩尔体积的状态方程。补充的分子动力学研究将进行估计冲击温度，并近似的热力学性质的高压冲击熔体。＊＊＊

96-14179 Miller The PI proposes an experimental and theoretical program to determine the equations of state of silicate liquids at high pressure to quantitatively understand the formation of deep mantle-derived magmas. Shock wave experiments are proposed for liquids that will lead to equations of state for the partial molar volumes of the important silicate melt constituents SiO2, MgO, CaO, Al2O3 and FeO. Complimentary molecular dynamics studies will be conducted to estimate the shock temperatures, and to approximate thermodynamic properties of the high pressure shocked melts. ***
