  • DISLOCATION CREEP OF MAGNESIOWUSTITE (MG0.8FE0.2O) 
    Stretton I.; Heidelbach F.; Mackwell S.; Langenhorst F. (2001)
    Magnesiowustite is likely the second most abundant and probably weakest lower-mantle phase. Its deformation properties will therefore influence the rheological and dynamic behaviour of this region. In this study magnesiowustite ...
  • RATE OF HYDROGEN-IRON REDOX EXCHANGE IN SILICATE MELTS AND GLASSES 
    Gaillard F.; Schmidt B.; Mackwell S.; McCammon C. (2003)
    A kinetic model for the rate of iron-hydrogen redox exchange in silicate glasses and melts has been derived from time-series experiments performed on natural rhyolitic obsidians. Cylinders of the starting glasses were ...
  • SHEAR DEFORMATION EXPERIMENTS OF FORSTERITE AT 11 GPA - 1400°C IN THE MULTIANVIL APPARATUS 
    Couvy H.; Frost D.J.; Heidelbach F.; Mackwell S.; Cordier P.; Nyilas K.; Ungár T. (2004)
    Synthetic forsterite samples were shear-deformed at 11 GPa, 1400°C in the multianvil apparatus. The deformation microstructures have been characterised by SEM, EBSD, X-ray diffraction peak broadening and strain anisotropy ...
  • WATER DIFFUSION IN SYNTHETIC IRON-FREE FORSTERITE 
    Demouchy S.; Mackwell S. (2003)
    The kinetics of hydrogenation of dry synthetic forsterite single crystals was determined by performing experiments under hydrothermal conditions. The experiments were performed at 1.5 GPa, 1000 °C for 3 h in a piston-cylinder ...
