This represents a continuation of research previously supported                 by NSF grant EAR83-19109 involving experimental and theoretical                 studies of the geochemistry of igneous vapor phases.  Specific                  objectives include (1) expansion of previously developed models                 of the processes involved in evolution of magmatic vapors to                    include the effects of batch vs. fractional vapor evolution,                    pressure-dependent vapor/liquid partitioning of chlorine, oxygen-               fugacity dependent partitioning equilibria, and the effects of                  crystallization of hydrous mineral phases and (2) further                       experimental studies of partitioning of ore metals (particularly                tungsten, zinc, copper, and molybdenum) among magma, vapor, and                 mineral phases.  The results of these studies will further our                  understanding of the fundamental processes involved in the end-                 stages of crystallization of igneous rocks, the evolution of                    magmatic vapors, and the formation of important ore deposits.                   This work is jointly supported by DOE Geothermal Technology                     Division.
