Water in the earth's crust has been found to be distributed heterogeneously in rocks by means of infrared microspectroscopy. Water is present as different chemical species in polycrystalline quartz aggregates: OH in crystal defects, fluid inclusions, water molecule layers at the grain boundaries and pore waters. Recent in-situ IR microspectrosopy revealed that the real physicochemical nature of water in silicates at high temperatures is different from that at ambiant conditions. In-situ dehydration kinetics of some hydrous minerals and glasses were investigated in order to provide quantitative bases for dynamic processes such as metamorphism, deformation and volcanism.
