The project will determine activity-composition relations and                   cation site distributions in MgAl2O4-FeCr2O4-Fe3O4 spinels using a              combination of solid electrolyte, phase equilibrium and electrical              measurements.  The enthalpy of almandine garnet obtained                        calorimetrically conflicts with values derived from precise phase               equilibrium measurements.  There are also discrepancies between                 the measured stability fields of almandine and hercynite spinel.                The free energies of almandine and hercynite will be determined as              a function of temperature using the ZrO2 electrolyte technique.                 Integration of thermodynamic data into an internally-consistent                 data base provides the means to calculate phase diagrams at very                high pressures and to make petrologic input into problems of                    earth structure.  This method will be used to investigate the                   reasons for observed reflections and conversions of seismic waves               at the interfaces between subducting slabs and overlying mantle.
