High Temperature and High Pressure Equations of State

Abstract

A program of investigation of theoretical equations of state, and ultrasonic measurements to 10 kbar and 800K is described. The theoretical work summarized includes: reduction and analysis of shock wave data for rocks and minerals, formulation of complete p-V-T equations of state for calculating high pressure and high temperature Hugoniots, release adiabats, and isotherms, and the examination of the empirical relations between bulk modulus and compressional velocity and density. The application of Kroner's theory of random aggregates to the prediction of rock elastic properties using single- crystal elastic constant data is discussed. Ultrasonic elasticity measurements on single crystal spinel (MgAl2O4) at ambient conditions, and on rock salt (NaCl) to pressures of 10 kbar and 800K are also summarized.
