Asset Details

  • Description:
  • P‐ρ plots of Hugoniot data and theoretical Hugoniot calculations for three starting materials of MgSiO3 composition. Filled symbols use shock travel times by streak camera (this study); open symbols use radiance duration in shock temperature experiments [Luo et al., 2004]; small open circles from Marsh [1980]. (a) Ultraporous MgO+SiO2. Calculated Hugoniot segments are shown for this starting material converting to candidate phases perovskite (pv) and low‐pressure phase (L.P.P.) melt. Segments interpreted to contain multiple phases are labeled mixed‐phase regime (M.P.R.). Note negative density change on melting at 32 GPa. (b) MgSiO3 glass. Calculated Hugoniot segments are for glass converting to pv and to H.P.P. melt as well as M.P.R. between en and H.P.P. assemblages. Change in density on melting at 110 GPa is negligible. (c) Enstatite crystal. Calculated Hugoniot segments are for enstatite (en) and for conversion to akimotoite (ak), pv, and H.P.P. melt as well as suitable M.P.R. segments. The dotted curve is a calculation of the Hugoniot for en converting to the newly reported postperovskite phase [Murakami et al., 2004; Shim et al., 2004; Tsuchiya et al., submitted manuscript, 2004]. Static data on the EOS of pv [Fiquet et al., 2000] are shown for reference. Note positive density change on melting at 170 GPa.
