Abstract:

岩石相变关系对限定地球内部物质成分和动力学关系有着重要意义.利用光探针在14~39GPa压力区间对热压烧结的辉长岩样品进行了冲击波加载实验.从16GPa开始,D-u线斜率发生明显变化,说明样品内发生了相变.利用原始的Hugoniot曲线结合地震波状态方程(SeismicEquationofState)得到了Birch-Murnaghan型的等熵压缩线和相变能.结合前人的实验结果,得到了辉长岩的Grüneisen参数γ0,约为2.3.计算得到相变后的矿物集合体在零压下的密度为3.41g·cm-3.根据以上参数分析得出,在此压力段辉长岩相变主要由长石的分解反应和石英的高压相变控制.
