Applied study of noble gas and light stable isotope gas geochemistry

The integrated study of noble gases and gases such as CO2, CH4 and N2 and their isotopes is an effective method developed rapidly in recent years. This paper reviews the study and application of the isotope indicators of two systems and the indicators of ratios such as CO2/3He, CH4/3He and N2/Ar in the geological field and gives a brief account of the application of gases such as CO2, CH4 and N2 and noble gases in probing the model of evolution of the Earth's atmosphere.
