The study will involve diamond-anvil experiments coupled with                   laser heating, spectrographic, and synchrotron x-ray diffraction                techniques to determine phase equilibrium in the mantle and core                of the earth.  Combination of high-pressure and synchrotron                     techniques provides the opportunity to improve current earth                    models significantly by providing experimental data on                          mineralogical and geochemical relations of the entire mantle-core               system.  It is proposed to build on current experimental results                obtained at conditions equivalent to those of the transition zone               to study in situ reversible phase relations.  The second part of                the study is to examine concepts of major element partitioning                  over the extensive pressure-temperature range of the lower mantle.              The third part of the study will be an experimental examination of              the core mantle boundary by determining the equilibrium (or the                 lack of equilibrium) between silicate-oxide-metal assemblages.                  The fourth part of the study will be a determination of the phase               equilibria of core compositions.
