Constraints on the composition of the earth's core can be                  obtained by comparing shock wave equation of state and                          compressional velocity at high pressure data to seismic data over               the pressure and temperature range present in the earth's outer                 core.  Knowledge of the composition of the core is inextricably                 interwoven with theories of the differentiation and thermal                     evolution of the earth.  Recent results from this project                       constrain the temperature of a core in terms of the melting point               of Fe and FeS.  This award provides support for continuation of a               program of exploration and measurements of the equation of state,               pressure-volume-temperature relations of candidate core                         materials- Fe, FeS, and FeO.  In addition to the equation of                    state longitudinal and bulk sound speed at high pressure and                    high temperatures using velocity interferometry and a new                       preheating technology will be measured.  The regime of shock                    measurements of preheated samples is 1000 - 2500 K both in core                 materials and some minerals of mantle.
