Abstract/Summary:
1. The equation of state of a molten komatiite was determined from 5 to 36 GPa via shock wave compression from 1550;Olivine (Fo;If komatiites are formed by ;2. The analytical method for measuring shear viscosity from the decay of perturbations on a corrugated shock front is examined. The relevance of initial conditions, finite shock amplitude, bulk viscosity, and the sensitivity of the measurements to the shock boundary conditions are discussed. The experimental results for water at 15 GPa are discussed, and it is suggested that the large effective viscosity determined by this method may reflect the existence of ice VII on the Rayleigh path of the Hugoniot.;3. Pure molybdenum was shocked to 96 GPa. Finite strain analysis gives a bulk modulus at 1400...
