Abstract: This paper introduced the principles of isotopic geochemistry of the fluid and the advance in this field, and discussed the characteristics of isotopic geochemistry related to earthquakes and the methods for distinguishing the earthquake precursors. Isotopic geochemistry may play an important role in earthquake monitoring and prediction, with which the origins and circulating process of fluid and cause of the isotopic - geochemical anomaly can be determined, and the ages of past earthquakes can be identified. In such a situation, some correct forecasts for further earthquakes might be proposed. It is worthy to emphasize the application and study of isotopic geochemistry in earthquake prediction.
