Hydrogen isotope exchange between tourmaline and water has been studied experimentally over the temperature range of 800-350°C. The hydrogen isotope equilibrium fractionation factor between tourmaline and water may be expressed as a function of temperature by the following linear equation: A study of the kinetics of hydrogen isotope exchange between tourmaline and water indicates that exchange is dominated by hydrogen diffusion. Over the temperature range of 800-450°C, the relation between the hydrogen diffusion coefficient and temperature for the tourmaline-water system is as follows: The activation energies for hydrogen diffusion are 128.0 kJ/mol (cylinder model) and 123.1 kJ/mol (plate model), respectively. For the temperature range 800-450°C, the relation of the hydrogen isotope equilibrium fractionation factor to the temperature (10 6 / T 2 ), chemical composition ( M ), and hydroxyl-stretching frequency ( f ) for systems of nonhydrogen-bonded hydroxyl minerals and water can be expressed as where M represents the mole fraction of designated cation in the mineral.
