Hydrogen and Oxygen Isotope Fractionation Mechanism in the Hydrothermal System and Its Geologic Significance

Hydrogen and Oxygen Isotope Fractionation Mechanism in the Hydrothermal System and Its Geologic... Abstract The geochemical behaviors of hydrogen and oxygen isotopes in the hydrothermal system and their inherent relationship with the water / rock exchange are discussed in this paper. In addition to the temperature conditions, the effective W / R ratio is another factor controlling the changes in H and O isotope compositions of the altered rock and hydrothermal water. Besides, the application and geological significance of the water‐rock exchange theory are also discussed in the light of the H and O isotope compositions and their variation characteristics of the mineralizing hydrothermal water and altered rocks from several mineral deposits. Finally, a brief evolutional model of H and O istotope compositions of meteoric and magmatic hydrothermal waters in a hydrothermal system is given. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Geologica Sinica (English Edition) Wiley
