Investigates igneous processes through experimental geochemistry in laboratory. Goal is to understand the structure, thermodynamics, and transport properties (diffusion and viscosity) of silicate melts and to apply this knowledge in the investigation of igneous petrogenesis. Together with his students, Dr. Baker is studying the thermodynamics of silicate melts at pressures to 2.0 GPa, the partitioning of trace elements between amphibole and melt, the structure of halogen-bearing silicate melts, the effects of melt composition on zirconosilicate crystallization, the effects of volatiles on granitic melt viscosities, the controls and effects of magnetite crystallization in basaltic compositions, and gold solubility in melts and its partitioning between silicate melts and sulfides. Future projects include studies of diffusion in silicate melts at high pressure, in situ spectroscopic studies of melts at high temperatures and pressures, and determination of partitioning water between silicate melts and nominally anhydrous crystals.
