通过使用 Grüneisen 理论和三阶有限应变理论，橄榄石-辉石组合中的弹性波速度被精确确定为压力和温度的函数。地幔岩石中 H2O 流体在高压和高温下的平衡分布已被确定，并用于估计橄榄石-辉石-H2O 系统中的 Vp 和 Vs。重要的是，橄榄岩-H2O 系统计算的速度连续再现了实验室测量的脱水蛇纹岩的绝对 Vp 和 Vs 值。橄榄岩-液体系统中已知的 H2O-CO2 流体平衡分布使人们能够根据矿物和液体弹性数据来估计含流体地幔岩石的弹性特性。
By using Grüneisen theory and third‐order finite strain theory, elastic‐wave velocities in olivine‐pyroxene assemblages are accurately determined as a function of pressure and temperature. Equilibrium distributions of H2O fluid in mantle rocks have been determined at high pressure and temperature, and are used to estimate Vp and Vs in the olivine‐pyroxene‐H2O system. Importantly, velocities calculated for the peridotite‐H2O system successively reproduce the absolute Vp and Vs values measured in the laboratory for dehydrated serpentinite. Known equilibrium distributions of H2O‐CO2 fluid in peridotite‐liquid systems allow one to estimate elastic properties of fluid‐bearing mantle rocks from mineral and liquid elasticity data.
