This award is for support of research in the following areas:  1)               Partitioning and distribution characteristics of the platinum-                  group elements in synthetic melts and crystals as a function of                 fO2 and fS2; 2) further development of Re-Os dating using high                  efficiency ionization sources and the application of these                      procedures to mantle and crustal rocks and minerals; 3) The study               of trace element distributions in crystal-melt equilibrium, in                  zoned crystals, in conjunction with crystal-chemical models; 4)                 The chemical-petrographic and isotopic study of submicroscopic                  inclusions in diamonds to determine the nature and age of trapped               mantle fluids and the correlation of potassic inclusions with                   carbonate and water contents; 5) The study of the concentration                 and distribution of large ion, lithophile elements in ultramafics               and the isotopic composition of Sr, Nd and Pb; 6) The study of U-               series disequilibrium and Th232/U238 ratios in fresh basic and                  ultrabasic rocks using mass-spectrometric methods; 7)                           determination of the CO2 solubility in synthetic silicate melts                 and in recent glasses; and 8) The investigation of theoretical                  models to explain both Nd and Sr isotopic patterns and trace                    element abundances in rocks which represent mixed magma sources.                Much of the funding will go for graduate student support,                       including the travel and supplies they will need.
