The objective of this work is to identify interrelations                   among mineral structure, bonding, physical properties and                       stability through the study of high-pressure minerals in the                    system CaO-MgO-FeO-Al2O3-SiO2-H2O.  Several research disciplines,               including crystal chemistry and crystallography, vibrational                    spectroscopy, single-crystal synthesis and solid-state theory,                  will be applied to well-characterized samples from this  group of               minerals.  A unique feature of this research will be the                        application of newly-developed techniques for studying single-                  crystals to hydrostatic pressures of 500 kbar (50 GPa) in a                     diamond-anvil cell with hydrogen or rare gases (helium, neon or                 argon) as pressure-transmitting medium.  Structural variations                  with pressure will be studied by x-ray crystallographic                         techniques; high-pressure structures up to the 500 kbar pressure                range will be performed for the first time.  Computational methods              based on density functional theory will be used to calculate                    structure, lattice dynamics, equations of state, and thermodynamic              functions for the important end member oxide and silicate minerals              in the system.
