英文摘要 | Shock compression experiments on natural compositions are imperative to accurately model planetary accretion and the interior dynamics of planets. Combining shock compression experiments from the Sandia Z Machine and the OMEGA EP laser facility with Density Functional Theory based Molecular Dynamics calculations, we report the first pressure‐density‐temperature (P‐ρ‐T) relationship of natural iron‐bearing olivine ((Mg0.91Fe0.09)2SiO4) on the principal Hugoniot between 166 and 1465 GPa. Additionally, we report the first reflectivities of natural olivine liquid in this pressure range. Compared to the Mg‐endmember forsterite (Mg2SiO4), the presence of iron in typical mantle abundance ( ∼9 weight % FeO) alters the US‐uP relation of olivine. On the other hand, the shock temperature and reflectivity of olivine are indistinguishable from forsterite where experimental conditions overlap. Both forsterite and olivine increase in reflectivity (and hence optical conductivity) with increasing temperature, with a maximum reflectivity of ∼31% at shock velocities greater than 22 km/s ( ∼800 GPa). |
