Experiments will be conducted to determine oxygen and hydrogen                  isotope fractionation between alunite and water over the                        temperature range of 250 to 450oC.  Exchange experiments will be                conducted in cold seal hydrothermal vessels with runs of 1 to 3                 months duration, and will involve coupling of isotope exchange                  with Na-K exchange to facilitate attainment of equilibrium.                     Knowledge of alunite fractionation factors will allow calibration               of alunite-quartz and alunite-pyrite isotope geothermometers, and               will permit interpretaion of alunite-bearing deposits in terms of               temperatures of formation and the chemical compositions of the                  various fluids that produced them.
