An understanding of the composition and crystal structure as               a function of depth in the mantle must rely on the comparison of                the in situ properties deduced from seismology with those deduced               from laboratory studies.  The laboratory studies can provide data               that are directly comparable with the properties of the mantle as               well as data that define theoretical models for predicting                      properties which are not measurable.  Single crystal acoustic                   velocities can best serve these needs, and Brillouin scattering                 provides a technique that can best define these data.  The thrust               of this research is to use this technique to directly                           characterize potential mantle minerals under simulated mantle                   conditions and to provide data for the purpose of directing                     theoretical modeling of material properties.
